What to do before the swab test？

Why implement full coverage of DNA swab testing?

What should be paid attention to in DNA testing?

The latest statistics on the COVID-19  released by Johns Hopkins University in the United States on the 9th show that the cumulative number of confirmed cases in the United States has exceeded 60 million.

Nucleic acid detection is an effective method for precise prevention and control.

After the COVID infects the human body, it will multiply in the respiratory system.

Using a nasopharyngeal swab to detect sputum can determine whether the human body is infected with the virus, and can quickly and accurately “find out” the virus.

The recent spread of the epidemic has brought new pressure to epidemic prevention and control around the world. There are even reports of a country’s leader being positive for the new crown. Mexican president tests positive for coronavirus. The President of Paraguay has tested positive for the new crown. Poland: President tests positive for coronavirus. Brazil’s president tests positive for coronavirus. etc.

On the basis of continuing to perform nucleic acid testing on key groups of people, close contacts, etc., to identify the infection chain as soon as possible, block the transmission route, control the spread of the epidemic, and implement large-scale full nucleic acid testing, we must achieve early detection, early reporting, Early isolation, early treatment, active search for potential new coronavirus infections, and targeted prevention and control measures are also adopted to protect the health of the masses, ensure the rational flow of the population, and maintain the stable development of social and economic life order. It is very important. significance.

What methods are available for COVID swab testing?

Nucleic acid detection generally adopts the nasopharyngeal swab detection method, including nasopharyngeal swab detection and oropharyngeal swab detection.

At present, most hospitals and institutions in our city use oropharyngeal swabs.

This method is the least painful and more convenient to collect samples.

Is it painful to take a throat swab?

A throat swab is a method of collecting a specimen from the throat area, it is painless, mild nausea or sore throat method, which can be relieved or disappear quickly after collection.

Are DNA tests dangerous to humans?

There is no harm to the human body, only when the throat swab is collected, a slight foreign body sensation will be felt when the cotton swab enters the throat.

What should I pay attention to before and after the inspection?

Before detection

Before the nucleic acid test, it is best not to eat for 2 hours, otherwise, it will cause vomiting.
Do not drink water, smoke, drink, or chew gum 30 minutes before sampling.

Before the examination, reduce the number of swallowing movements, and do not do throat-clearing movements, such as expectoration and spitting.

For example: before the nasopharyngeal swab collection, the subject should provide the collector with the relevant past medical history or related matters.

Such as history of nasal surgery, nasal septum, blood disease, throat disease, or taking anticoagulant drugs.

Be sure to wear a mask before going to the test, take out the mask before the test, and put it on immediately after the test. You can prepare a spare mask, which can be replaced at any time after pollution.

Checking

When collecting oropharyngeal swabs, the subject should tilt his head back, relax as much as possible, take a deep breath, and open his mouth to make an “ah” sound, which will help reveal the throat, but symptoms such as irritating dry cough, nausea and vomiting may occur during this process.

Nasopharyngeal swab During the process of nasopharyngeal swab, symptoms such as swelling, itching, and sneezing may occur, which can be covered with a tissue or elbow.

After detection

Leave the collection site immediately after collection to avoid spitting and vomiting near the collection site.

You must pay attention to hand hygiene before and after the nucleic acid test.

You can wipe your hands with your hands, or you can use hand sanitiser, disposable alcohol, and disinfectant cotton pads.

 

Important reminder:

●Be careful to wear a mask, do not expose your nose and nose, do not take it off at will, or pull the mask to your chin.
●There should be an orderly queue, keep a distance of 1 meter, do not get together, do not gather.
●When waiting in line for a long time, pay attention to sun protection, sun protection, scientific hydration, and a reasonable diet.
● Try to avoid taking public transportation to the nucleic acid test sampling site.

The current situation of epidemic prevention and control is very complicated.
Every day, take care to protect your body.
Wear a mask and follow the epidemic prevention regulations.
Protect yourself and protect others at the same time.
New coronavirus pneumonia cases.
Please accept the general guidelines for prevention and control.
Daily Travel Prevention Control Guidelines.
Take the bus, take the subway.
To minimise contact, payment can be made using a transport card or a mobile app.
Avoid touching public facilities such as seats, armrests, car doors, and armrests with your hands as little as possible. If you do, do not touch your mouth, eyes, and nose directly with your hands, and disinfect your hands in time to avoid contact infection.

Hospitals and other places, after returning home, you should disinfect your outerwear.

During the outbreak of the new coronavirus pneumonia, while everyone is doing personal protection, they are also very concerned about the epidemic situation.

Originally, the social season in winter and spring was a period of the high incidence of common colds and flu, and the most important means to control the epidemic was to screen out the real patients with new coronary pneumonia from many respiratory patients.

The following small series will introduce some common virus sampling detection methods for you.

Nasopharyngeal swab

Collect nasopharyngeal swab specimens within 3 days of the onset of the patient as much as possible.

Measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be at least half the length from the earlobe to the tip of the nose so that the swab stays in the nose for 15 ~30 s.

Gently rotate 3 to 5 times, quickly put the swab into a sample collection tube containing 2 ml of lysis buffer (the same as the lysis buffer in the nucleic acid extraction kit) or a cell preservation solution containing RNase inhibitors, and insert the swab.

Then break the sterile swab rod near the top, screw the cap tightly and seal it with parafilm.

Oropharyngeal swab

Collect throat swab specimens from patients within 3 days of onset as much as possible. It is advisable to use a sterile flocked swab for sampling, wiping the posterior pharyngeal wall with moderate force, avoiding touching the tongue; quickly put the sterile swab into the collection tube used for collecting nasopharyngeal swabs, and break it near the top Sterile swab rod, screw cap tightly and seal with parafilm.

Anal swab (feces)

For patients with gastrointestinal symptoms such as diarrhea in the early stage of the disease, an anal swab should collect a stool sample (soybean size) of 3-5g.

The specimens were collected in a screw-cap specimen collection tube containing 2 ml of normal saline (RNase inhibitor can be added if available) and sealed with parafilm.

How to collect nasopharyngeal swabs

There is absolutely no need for the sampler to stand directly opposite the patient. Regardless of whether the patient is sitting or lying, right-handed patients can stand on the right side of the patient, and left-handed patients can stand on the left side for sampling operations.

The advantage of standing on the side is that if the patient has a cough, sneeze, etc., it can be avoided in time.

After the nasopharyngeal swab is passed through the nostrils.

It is perpendicular to the coronal plane of the head or the face and penetrates deep from the inferior meatus to the posterior wall of the nasopharynx, and it is enough to feel the wall.

The nasopharyngeal swab enters the nasal cavity to a depth of approximately the distance from the tip of the nose to the earlobe (see figure).

The “American Society for Microbiology Clinical Microbiological Specimen Submission Guidelines. ” We ask to twist the nasopharyngeal swab on the nasopharyngeal mucosa, hold it for 10-15 seconds, and then take out. Children’s cooperation is poor.

We generally take out the Flocked swab in three to five seconds after fully twisting it 2-3 times.

Except for paying attention to the depth of the swab. We should also note that there is always the habit of having the patient lift their head completely, bend the swab, and take a sample. This is wrong.

In fact, the above approach is wrong. This operation will cause the swab head to stay in an incorrect position. And the final sample obtained is not a standard nasopharyngeal swab specimen.

What is a Medical Swab

In the COVID-19 sampling, medical flocked swabs are the most commonly used testing method.

Application: oral mucosal cells, oral microorganisms, virus sampling and transportation, DNA/RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling and other fields.

In addition, we can also use medical cotton swabs for the collection and transportation of DNA for paternity testing.

As well as the collection, preservation and transportation of flu specimens.

According to the material, medical swabs can be divided into cotton swabs, foam swabs, non-woven swabs, flocked swabs and other products. Among them, the market share of cotton swabs is higher, reaching 76%.

According to the application field, medical swabs include gynecological, cervical and vagina sampling swabs; oral, nose, and pharynx sampling swabs; laboratory test sampling swabs; virus and bacteria sampling; disposable sampling swabs; sterile cell sampling And other products.

However, due to the influence of new coronary pneumonia and the popularization of nucleic acid testing, the proportion of medical swabs used for specimen sampling is increasing.

With the continuous improvement of medical conditions in developing countries around the world, the application demand for medical swabs is on the rise.

In 2020, the global medical swab market will reach 400 million U.S. dollars, with an output of about 38.4 billion pieces.

Moreover, due to the development of the world economy, the price of medical cotton swabs has shown an upward trend.

Choose the right medical swab

Swabs are one of the most commonly used disposable devices in the medical industry. But how do you know which application to choose? We have put together a brief overview on how to choose the right medical swab for your specific needs.

Cotton swab

The tip of American pharmaceutical-grade spun cotton fiber has become the standard for applicators for all applications from basic patient care to crime scene investigation.

With strong water absorption capacity, softness, low cost and safety, the performance of the cotton swab is consistent and reliable.

However, it is generally not recommended to use cotton swabs for specimen collection.

why? The characteristics of this natural material prevent the sample from being effectively released, and the naturally occurring fatty acids in this material interfere with the processes used in microbiology and DNA extraction and have proven harmful to organisms.

Rayon cotton swab

"<yoastmark

Rayon is a synthetic fiber made from wood pulp.

Although classified as synthetic fiber, it is actually a natural material.

Unlike cotton, artificial fiber removes materials that may sample or react to samples for transportation and processing during the production process, so it is usually used to sample for diagnostic tests.

Polyester fiber swab

"<yoastmark

Swab head material adopts polyester filament winding.

Polyester fiber is used for microbial collection, rapid diagnosis and PCR detection.

The polyester scraper has a higher release rate, but its cost is higher than cotton swab and rayon swab.

Foam tip swab:

Foam swab

Foam swab

The swab made of medical polyurethane is a very good diagnostic material, especially suitable for cell sampling.

The number of holes on the surface is generally 100 PPI (holes per inch).

This material has good hydrophilicity and poor absorption of hydrophobic substances.

Used in occasions where resistance to chemical corrosion is required, and it is also used for DNA and microbial sampling.

Synthetic swabs (rayon and polyester) are used to collect bacterial culture specimens, rather than cotton swabs that may contain inhibitory or toxic substances.

Flocked swab:

flocked swabs

flocked swabs

First developed flocking technology for cosmetics and industrial production.

Because of the planting process and the use of multi-head bifurcated polyester fiber materials.

The flocked swab has a very high absorption and release rate, and it is also effective for molecular sampling and absorption.

Some institutions designate to conduct research on nucleic acid sampling and certain genome analyses.

At present, the development of swabs not only reflects the changes in the materials of sampling swabs, but new demands in the fields of nursing, testing, and scientific research have led to the multi-dimensional development of swabs.

COVID-19 Saliva Collection Kit

How accurate are saliva swab DNA tests?

Posted on by

Is the DNA test of the saliva swab accurate?

Many people doubt the accuracy of the saliva swab test.

However, you can rest assured, because the accuracy of oral saliva swab testing is as accurate as other DNA testing methods.

Moreover, this is not the same as a finger puncture or a blood test, it is not painful at all.

In recent years, DNA testing has become more and more popular.

Whether you want to confirm your parental relationship, understand where your genes come from or want to optimize your exercise.

We are currently working on direct-to-consumer DNA testing of saliva swabs.

You have decided to use DNA testing to better understand your body and optimize your training.

However, before you take the first step and buy a set of home DNA testing kits, you should have some concerns.

Although most of the feedback and research has been confirmed to be positive, we are here to learn more about this and help you make an informed decision.

How much saliva is needed for a DNA test?

Saliva Sample Collection Kit :Disposable saliva DNA RNA sampling tube

Saliva Sample Collection Kit: Disposable saliva DNA RNA sampling tube

2ml-4ml.

The saliva collection components are easy to use, and each set has detailed instructions.

You can provide samples for different health conditions, including common medications used during pregnancy, colds or flu (including medications for acid reflux or heartburn).

But if you want to use drugs to reduce the white blood cell count, such as chemotherapy, you’d better wait two weeks or wait until the white blood cell count returns to normal.

After mixing with DNA stabilizing buffer, the temperature range of your saliva sample (-4oF to 122oF) is stable.

Please send the collected samples to the laboratory as soon as possible.

Is the DNA test at home accurate?

Yes, DNA testing at home is very accurate.

You will only encounter errors when the genetic sample is damaged (for example, you have eaten before the sample is collected) or the laboratory quality is poor.

Therefore, it is necessary to choose a well-known DNA testing supplier for testing.

An accurate genetic test report can know in advance whether the body is in danger of disease.

By improving the living environment and behaviour habits, avoiding or delaying the occurrence of the disease, or determining whether there is a specific drug in the case of malignant disease.

Target, so as to more accurately select the treatment method.

The results in each report are derived from at least three peer-reviewed research papers.

It just repeats the genes that have an impact on health, health and nutrition.

This means that you can change the way of real-life based on the genetic variants you carry.

Through strict internal and external procedures, we have passed ISO27001 certification to identify risks, evaluate all control systems, improve our reliability and security, and comply with international data security standards, so as to ensure that our customers and business partners can trust us.

What can you do to ensure that your DNA test results are accurate?

In order to ensure that your DNA test results are accurate, you need to follow the instructions at the back of the box.

Before starting, please read the instructions carefully:

Before wiping dry, make sure you have nothing to eat or drink.

-The best time to take the exam is to brush your teeth in the morning and the first thing before drinking the first cup of tea.
Before taking the test, it is best to open the sealed mouth swab to ensure that it will not be affected.

After removing the cotton swab, open your mouth and use a pointed tip (cotton swab, slightly larger) to gently wipe your cheeks.

Try not to scrub vigorously, because the important part of the sample is saliva.

Be sure not to put paper towels in the plastic container provided.

Take care to break the pole where it is needed.

Fill out the attachments, sign and seal the enclosed envelope, and then send it to the laboratory for inspection.

Bear with patience and watch your test. This process will start with the receipt of samples in the laboratory and will take 10-14 days.

Is the accuracy of mouth swab detection relative to other DNA collection methods?

Because the saliva swab is noninvasive, many people question its accuracy.

However, you can rest assured that the accuracy of oral swab detection is as accurate as other DNA detection methods. And, unlike finger punctures or blood tests, it doesn’t hurt at all.

Whether you are building a cabinet in IKEA, pressing a map or doing DNA testing, you can get accurate results as long as you follow the instructions.

Remember, DNA testing is wrong only if your test results are wrong or you don’t follow the instructions.

Cost is an important factor in performing such tests, so it must be studied.

Often, you don’t just pay for the test suite. You also have to pay a test fee to analyze your results. If the test you selected does not belong to the laboratory, please choose a supplier with a good reputation and excellent laboratory.

Every laboratory we use will conduct regular spot checks to ensure that your samples have been tested correctly and your results are 100%.

What’s The Difference Between COVID-19 Rapid and PCR Tests?

What’s The Difference Between COVID-19 Rapid and PCR Tests?

Posted on by

What’s The Difference Between COVID-19 Rapid and PCR Tests?

As New Year’s Day approaches, the number of new crown infections is also rising. Therefore, once you have symptoms of infection. Or you are exposed to the new coronavirus. If you are going to an environment with a high risk of infection.

You must continue to be tested.

Currently two COVID-19 detection methods-polymerase chain reaction (PCR) test (also known as reverse transcription-polymerase chain reaction test) and a rapid antigen test.

So, which detection method should we choose? What is the difference between the two?

On the COVID-19 website, terms such as PCR, rapid test, and antibody test are difficult to understand and which one is correct for you. In this article, our goal is to explain the difference between the two most common tests for diagnosing COVID-19: rapid antigen test and polymerase chain reaction (PCR) test.

Rapid antigen test

Antigen test (often called rapid test). This test detects protein fragments specific to coronavirus. We can do the antigen test in a clinic, doctor’s office or hospital. The turnaround time for results is usually very fast, and in some cases, we can get report results within 15 minutes. There are usually false negatives (the results indicate that the patient does not actually have a coronavirus) or false positives (the results indicate that the patient does not actually have the coronavirus).

If you feel unwell and have undergone a rapid negative test, you may need to undergo a PCR test for further confirmation. However, when someone is at the peak of infection, rapid antigen testing usually provides accurate results because this is when the virus levels in the body are highest.

The rapid antigen test is usually used as a screening tool to detect that you may be infected with the new crown, but PCR monitoring is required to confirm the final result.

Although a negative rapid antigen test result does not necessarily mean that you are not infected, it at least protects your contacts than not testing at all.

PCR TEST

PCR swab tests are similar to rapid tests in several respects because they can be used in symptomatic or asymptomatic patients and can be tested with nasopharyngeal swabs.

The swab test is considered the “gold standard” for SARS-CoV-2 detection. This test actually detects RNA (or genetic material) unique to the virus, and it can detect the virus within a few days of infection, even for those who have no symptoms. This test can be performed in a clinic, hospital or even in your car. The turnaround time is longer, generally in the range of 2-3 days, but the result may be within 24 hours. When the demand is high, the result may take a week or more.

What if the rapid test is negative but there are still symptoms?

The current recommendation is that if you still have symptoms and the rapid test is negative, you should have a confirmation test (PCR test). This is especially true if you have high-risk exposures. High-risk exposure is considered to be contacted with a COVID-19 positive individual for more than 15 minutes within 24 hours, and the distance between you and the individual is no more than 6 feet.

What kind of test should be done? When will it be done?

RT-PCR (reverse transcriptase-polymerase chain reaction) detection if the following situations occur:

1. Symptoms of new crown infection appear.
2. Having contact with people infected with the new crown.
3. The rapid antigen test result is positive, and PCR identification is required.
4. The Ministry of Health requires testing before lifting the quarantine.
5. The Ministry of Health requires that an inspection must be carried out before obtaining permission to travel to a certain area.

If you want a quick antigen test:

1. Have a plan to go to a place with a high risk of infection.

2. Contact with high-risk groups (such as the elderly) and hope to protect them.
3. You have symptoms of COVID-19, but you cannot go to the PCR test site.
4. Activities with a large number of participants in the field, if indoor activities are carried out, the risk of infection is greater.
5. Check whether you have the SARS-CoV-2 virus as soon as possible.
6. Participate in regular COVID monitoring projects.

    COVID-19 Swab Test : Positive Covid Test

    COVID-19 Swab Test : Positive Covid Test

    Posted on by

    Despite the recent surge in coronavirus cases, most Premier League clubs hope to continue playing during the holiday season. Due to the Covid-19 outbreak, only half of the game last weekend was left, and each round of new swab tests will continue to yield results of increasing cases.
    This led several top coaches to question the safety of continuing.
    Currently, all fans can still enter the stadium. However, there are reports that the UK may adopt secondary measures after Christmas. According to these regulations, only 2,000 spectators are allowed to watch the game.

    Here is how to test for COVID-19 and what to do if the test result is positive.
     Stock up on healthy foods and anti-fever medicines, and avoid contact with others. Try to watch football matches at home.

    COVID-19 testing methods.

    COVID-19 infections have surged again, so you may find that you test positive.
    With the highly contagious variant of Omicron circulating in many countries, reinfection is common, and people who are vaccinated may be susceptible to mild infections.
    It is important to take precautions and be prepared to act if you are infected.

    Here is how to do it:

    How to confirm if you have COVID-19

    As we all know, the symptoms of Covid-19 include “fever, fatigue, and dry cough”. Some patients will have symptoms such as nasal congestion and runny nose. Viruses are also a very large family. In the face of a turbulent epidemic, how doctors can quickly distinguish whether it is a “2019-nCoV” virus infection in the first place is obviously the key to fighting the epidemic.

    What are the symptoms of COVID-19?

    Some people infected with the virus have no symptoms. When the virus does cause symptoms, common symptoms include fever, body aches, dry cough, fatigue, chills, headache, sore throat, loss of appetite and loss of smell. In some people, COVID-19 can cause more serious symptoms, such as high fever, severe cough, and shortness of breath, which usually indicates pneumonia.
    People with COVID-19 can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may or may not have respiratory symptoms.
    For example, COVID-19 affects the brain function of some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, tastelessness, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.
    In addition, some people have gastrointestinal (GI) symptoms such as loss of appetite, nausea, vomiting, diarrhea, abdominal pain, or discomfort related to COVID-19.
    If you have been (or you suspect you may have been) exposed to COVID-19, You should also test whether you are experiencing symptoms.

    How to test for COVID-19?

    Special diagnostic tests must be performed to confirm that someone has an active coronavirus infection.

    In most cases, the clinician will take a nasopharyngeal swab (or nose and throat swab).

    Certain tests can be performed with saliva samples. Then check the genetic material of the virus in the sample (PCR test) or specific viral protein (antigen test).

    Antibody testing can tell if someone has COVID-19. But an infected person does not immediately start to produce antibodies. It can take up to three weeks for a blood antibody test to become positive. This is why it is not useful as a diagnostic test for people with new symptoms.

    How reliable is the test against COVID-19?

    COVID-19 Swab Test: flocked swab test kits

    COVID-19 Swab Test: flocked swab test kits

    Currently, there are two types of diagnostic tests in the United States. The PCR test can detect viral RNA. Antigen tests (also called rapid diagnostic tests) detect specific proteins on the surface of the coronavirus. Antigen test results may recover within 15 to 45 minutes; you may need to wait a few days or longer to get PCR test results.

    The accuracy of any diagnostic test depends on many factors, including whether the sample is collected correctly. For PCR tests that are usually analyzed in the laboratory, the test results may be affected by the conditions under which the test is shipped to the laboratory.

    The test time will also affect the results. For example, if the test is performed on the day of infection, it is almost certain that the test result will be negative because there are not enough virus particles to detect in the nose or saliva. If the test is performed a few days after infection or a few days after the onset of symptoms, the chance of getting a false negative test result will decrease.

    Generally speaking, if the test result is positive, it is almost certain that the person has been infected.

    The negative test result is uncertain. The false negative rate of antigen testing is higher. If your antigen test result is negative, your doctor may order a PCR test to confirm the result.

    Self-quarantine for 10 days

    If you test positive for the virus, you should self-quarantine for 10 days.

    CDC says this means don’t leave your home unless there is an emergency.
    How soon after contracting the new coronavirus will I start the infection?
    Emerging research shows that people are actually most likely to spread the virus to others within 48 hours of the onset of symptoms.

    If you live with your family or roommates, keeping your distance is a challenge.
    The ultimate goal is that you do not share the air with anyone else.

    This means sleeping in a separate room with a separate bathroom, rather than in the same space, such as a kitchen or living room.

    Ideally, have friends or family members leave food and drinks outside the door for you to collect.

    What does self-quarantine or quarantine mean? What should I or shouldn’t I do?

    It is important not to spread the infection to other people during the recovery process.

    Although home isolation or home isolation sounds like a stay, you should be prepared for a long time during which you may feel disconnected from others and feel anxious about your own health and the health of your loved ones.

    Staying in touch with others over the phone or online can help maintain social relationships, ask for help, and update others based on your situation.

    Separate yourself from other people and animals in the house.

    Stay in a specific room as much as possible and stay away from other people in your home. Use a separate bathroom (if available).
    Wear a mask when you are sick.

    Wear a mask when you are with others or pets, and before entering a doctor’s office or hospital.

    Cover up coughing and sneezing.

    When coughing or sneezing, cover your mouth and nose with a tissue, and then throw the used tissue into the lined trash can.

    After sneezing, immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% for cleaning.

    Clean your hands often.

    Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing or sneezing; going to the bathroom; before eating or preparing food.

    If soap and water are not readily available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% to cover all surfaces of your hands and rub them together until it feels dry.

    Avoid touching your eyes, nose and mouth with unwashed hands.

    Don’t share personal household items

    Do not share dishes, drinking glasses, cups, eating utensils, towels or bedding with others or pets at home.

    Monitor symptoms

    Check your temperature twice a day to monitor if you have a fever and stay alert for coughing or breathing difficulties.

    If you are asymptomatic and start to have a fever or fever, cough or difficulty breathing, immediately limit contact with others (if you have not already done so).

    Call your doctor or local health department to determine if you need a medical evaluation.

    *Just collect, capture and transport:

    Peel off the pouch, collect cell samples,

    and clip the applicator shaft into the provided delivery medium or cuvette tube.

    *Quantitative volume transfer:

    Measurable and consistent absorption and transfer from the patient to the test tube,

    without an internal mattress core,

    disperses and holds precious samples like traditional fiber swabs.

    In contrast, the entire sample remains close to the surface for rapid and complete elution.

    *Vertical nylon fiber:

    Such as a soft brush, can improve the collection of cell samples.

    The capillary interaction between nylon fiber bundles not only facilitates the strong water absorption of cell samples

    but also keeps the cells close to the surface, which is more convenient for elution.

    *Certified without inhibitors and interferences:

    Swabs collected are certified DNase, RNase free, and human DNA free.

    They also do not contain any PCR inhibitors.

    Certificate of analysis for each batch.

    *Ideal for automation:

    Compared with the traditional fiber wound swab, the 4n6 DNA swab only released a small amount of fibre during the extraction process.

    This avoids the risk of clogging the pipettes and probes used by the liquid handling robot.

    advantages of flocking as a sampling swab

    When it comes to sexual sampling swabs, I believe you don’t feel strange at this time.

    Because most of the detection tools used for nucleic acid detection are disposable sampling swabs.

    Sampling swabs directly contact our human organs, such as nasal swabs and pharyngeal swabs for nucleic acid detection.

    So the material selection of sampling head is very important, and the material of sampling head is closely related to subsequent detection. The sampling swab shall ensure the sampling amount and release amount, and the selected material shall not have substances that affect the subsequent detection.

    ·Compared with the traditional winding swab, the amount of samples collected and released by flocked swab is three times higher, and it will not cause harm to human body.

    ·The sampling time of flocking swab is 3-5 seconds, which is fast and convenient to improve work efficiency.

    Only by extracting samples faster can we complete the collection and analysis more efficiently.

    ·Moreover, through the directional friction effect of the brush fiber layer,effective collection of samples.

    Therefore, the flocking swab is particularly conducive to the collection of trace DNA.

    ·A large number of clinical experiments show that compared with ordinary sterile cotton swabs, flocking swabs have a better effect on the collection and transportation of clinical microbial samples. This is especially true for those specimens that cannot be submitted for examination in time and placed for too long.

    Sterile Flocked Nylon Swab with 80mm Breakpoint.

    Flocked swabs consist of nylon fibres to provide not only excellent sample collection but also release of that sample into Transport media.

    The term “flocked” refers to a process of attaching fibers of variable length flocking to a surface coated in the adhesive in order to enhance sample collection.

    Flocked swabs provide advantages for a variety of specimen collection procedures employed by medical and laboratory professionals. The swab is designed to be ergonomic for the user as well as for patient comfort and to optimize sample collection.

    The flocked nylon fibers act similar to a fine bristled brush, which creates thousands of contact points whereby, cells, microscopic organisms or particles may be collected. Sterile flocked swabs are the preferred choice when collecting samples from the nasal cavity.

    Name: nylon flocked swab for nasopharynx, plastic rod, aseptic independent packaging.

    This product is produced by new technology in Australia. A large number of clinical trials abroad show that compared with ordinary sterile swabs, nylon flocking swabs have better collection and transportation effects on clinical biological samples, especially for those samples that cannot be submitted for inspection in time and placed for too long.

    Flocked Nylon Swab Advantage:

    1. Connection strength: when the moving speed of the fixture of the tensile testing machine is 200 mm / min; The pull-out force between the sampling head and one end of the connecting rod shall not be less than 2n,

    2. Breaking strength: when the test span is 6cm, the swab shall be able to withstand 4N axial static pressure for 15s without permanent deformation or fracture phenomenon.

    3. Rotational friction degree: spray nylon fluff on the ABS rod after viscose. The rubbing fastness refers to that the test is not greater than 2n, the rotational friction is not less than 3 times at 360 degrees, and the amount of nylon fluff on the surface is not greater than 2.

    The sterile disposable sampling flocked swab has passed the whole project testing by the national quality supervision instrument testing centre, and the qualified test report zc1011965 / 96 / 97 has been issued.

    The sampling swabs are divided into pharyngeal swabs, oral swabs, DNA swabs and cervical swabs, which can be used by various laboratory testing centres.

    The sampling flocking swab is three times higher than the traditional winding swab in the number of samples collected and released and does not cause damage to the cell sample, so as to ensure the survival rate of the cell sample, no residual fatty acids, no impact on the test and detection effect, and no harm to the human body.
