What is Swab Test

Posted on 2022年3月8日2022年3月22日 by Dr. Lee

If you are considering whether you should get a COVID-19 swab test, symptomatic or asymptomatic.

Under normal circumstances, the virus is spread through the air to our nose or mouth.

We have to wear masks to prevent the infection of the virus from the source.

Assuming we are unfortunate enough to carry the new crown, the virus will enter the throat through the nose and mouth, and then enter the alveoli through the trachea and bronchi.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs. The sample is collected from your nasal cavity or mouth when the nurse’s sister gives you a nucleic acid test.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs, which are the samples taken by the nurse sister from your nasal cavity or oral cavity when you are doing nucleic acid testing.

Due to the convenient operation and high accuracy, these two methods have been widely used. Now I will tell you about nasopharyngeal swabs and oropharyngeal swabs in detail.

What is a nasal swab test?

Specimen Collection Swab

Our respiratory tract is divided into the upper respiratory tract and lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. In medicine, the cricoid cartilage is used as the boundary to distinguish.

The nasopharyngeal swab test is a medical test method. A medical cotton swab is used to wipe a little secretion from the nasopharynx of the human body, placing it in a special incubator, and placing it in a temperature-controlled device for cultivation. Can understand the patient’s condition, oral mucosa and pharyngeal infection.

Compared with oropharyngeal swabs, nasopharyngeal swab sampling has the following advantages:

1. When collecting oropharyngeal swab samples, the sampler can see the location of the pharynx to be sampled, and the irritation to the oropharyngeal mucosa may cause the sampled to cough, nausea, and even vomit.

2. When collecting nasopharyngeal flocked swab samples, the irritation to the nasopharyngeal mucosa is relatively small if the operation is standardized.

3. But the sampler cannot see the location of the pharynx for sampling, and mainly relies on the resistance felt by the hand to complete the sampling, so the technical requirements are higher, and the tools used are also more complicated.

4. It can stay in the pharynx for a longer time to obtain a sufficient amount of specimens, which is why the positive rate of the swabs reported in the literature is higher than that of oropharyngeal swabs.

5. The patient’s tolerance is good. After the skilled operation, sampling can be performed without anesthesia, but surface anesthesia and contraction of the nasal mucosa can be performed first for beginners.

How to Use Specimen Collection Kit

What is a Specimen Collection Kit?

Sample collection kits provide all the components needed to secure samples and send them to laboratories for diagnostic. Environmental sampling and research purposes. Timely collection and processing of samples are critical to ensure accurate results and prevent analytical errors.

Specimen Collection Kit Contains:

Individually packaged sterile specimen collection flocked swab;
10ml virus sampling tube, containing 3ml Viral Transport Media;
Sterilization packaging, Individual in Paper peeled pouch;

The novel coronavirus (2019-nCoV) is an RNA virus. Improper storage or transportation of samples after collection may result in the degradation of part of the nucleic acid and affect the test results;

In addition, samples that have not been inactivated virus can easily lead to indirect infection of operators.

The covid-19 sampling kit independently developed by Cell medical can not only prevent the degradation of viral RNA but also inactivate the virus.

While ensuring the test results, it can reduce the risk of biological infection during the inspection process.

Product description

Viral Transport Medium Chin, VTM kits For COVID-19. Cell medical not only produces sampling swabs but also virus sampling tubes.

Analyzing material effectively starts with collecting samples with the right tools, whether it’s collecting samples from the body to aid in medical diagnosis, identifying potentially harmful pathogens from the environment.

Or collecting samples from crime scenes to aid in investigations.

However, it is also important to ensure that contaminants do not come into contact with the sample as it travels to the laboratory. Given the plethora of options available for each of these missions, choosing the right collection and transport vehicle can be overwhelming. This is where a specimen collection kit can prove invaluable.

Features:

1. Safety: Sampling and virus inactivation are carried out simultaneously, which greatly reduces the operator’s infection risk;

2. Stability: keep the sample stable, avoid nucleic acid degradation, and ensure the accuracy of the test results;

3. High efficiency: Inactivated virus samples can be detected in conventional PCR laboratories, and the collection tube can be adapted to the Tianlong automated nucleic acid extraction system, which improves the detection efficiency of samples.

Instructions:

What is the Specimen Collection Kit?

As pointed out over, example collection packages have shown very usefully in securing examples for analysis in a large range of clinical, environmental and research study applications.

Nasopharyngeal samples collected by swabbing the upper retronasal vocal cords can supply analysis confirmation for a series of viral as well as bacterial infections, consisting of influenza, COVID-19, enterovirus D68, as well as other respiratory system conditions.
Fecal samples can be gathered by anal or fecal swabs as well as can aid clinicians detect a series of intestinal microbial infections.
A vaginal swab example can help determine the visibility of Group B Streptococcus or Streptococcus agalactiae, a type of microorganisms found in the digestive system and also birth canals of a quarter of pregnant ladies, to name a few conditions.
Food sampling is not just important for recognizing the potential presence of foodborne pathogens but is a crucial step in maintaining conformity with FDA food security requirements.

How to choose the right specimen collection kit?

It is necessary to discover a sampling collection set created for your particular end-use. This consists of using the flocked swab that best matches your sampling collection needs. As an example, foam swabs might use elution characteristics best matched for environmental and also food sampling, while polyester or crowded swabs may supply a combination of collection attributes and also person comfort far better fit for medical usage.

Nonetheless, it is not constantly necessary to utilize a sample collection package created for usage with the example cpu’s very own brand name of the fluid transfer system. Validation examinations can aid clinicians, food mill and also other samplers, and also labs recognize precise and also affordable sample collection kits. Verifying shipping systems from several suppliers has come to be a common practice in research laboratories around the globe, not just to ensure sustainable supply, but likewise to compare item top quality and expense.

Does the Nasal Swab Hurt?

Does nasal swab test hurt?

A nurse is doing a swab test on a patient

The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

Why Choose Anal Swab Covid Tests

Posted on 2022年1月22日2022年1月22日 by Dr. Lee

Why Choose Anal Swab Covid Tests

A friendly netizen said,

“The anal test first asks you to take off your pants and lie on the bed,

The paramedic then stabs (anus) twice with an anal swab,

shallow once deep

In addition to the endless shyness in the whole process,

Nothing else feels like it! ”

A shy handsome man

Xiaolee will tell you why you need to do anal swabs.

Currently screening for COVID-19,

Mainly use an oropharyngeal swab and nasopharyngeal swab nucleic acid detection,

Because of its convenience and speed, it is suitable for large-scale screening;

Nasopharyngeal Swab Sample

However, some asymptomatic or mildly infected people,

The disease recovered quickly after infection,

Nucleic acids in the respiratory tract and pharynx are undetectable within 3-5 days.

longer duration of nucleic acid-positive stool or anal swab,

Therefore, adding anal swabs can improve the detection rate,

Effectively reduce the probability of false negatives,

Reduce missed diagnoses!

One of the anal swab samplings poses

Friends who have done nucleic acid swab tests have experience,

In previous tests,

The most uncomfortable part should be the part of the nasopharyngeal swab,

To poke the nose is to poke deep into the soul.

According to the description of the anal swab recipient,

“The whole process was lying in bed and the medical staff helped.

Insert the tip of the sampling cotton swab into the anus and turn it a few times.

Twice in total, each for about 10 seconds.

Although a little surprised and a little embarrassed,

But understandable and bearable,

After all, this rule is for everyone’s sake. ”

Many Chinese friends who have returned to China for quarantine

I have also experienced the subtle taste of it.

What is Pooled Sample Test?

Posted on 2022年1月20日2022年1月20日 by Dr. Lee

Pooled Sample Test?

With the 2019 coronavirus disease (COVID-19) pandemic, doing a good job in viral nucleic acid detection is the top priority. However, detection of the virus is still limited due to resource constraints. Pooled sample testing offers a way to significantly improve testing power.

“mixed nucleic acid test” or “Pooled Sample Test”, referred to as “mixed test”.

Which means that two or more samples are mixed and tested. method for positive samples.

What is the difference between the “mixed collection” of community nucleic acid testing and the “single collection” of the hospital?

Why do community streets adopt the mixed mining model?

Under what circumstances should I test individually?

What is pooled COVID testing?

The so-called “mixed detection” of nucleic acid.

Takes throat swab samples from multiple people and puts them together for viral nucleic acid detection.

Pooled Sample Test VTM Kits

In fact, Medical use of Pooled Samples is common.

In blood collection systems such as apheresis stations.

We use pooled samples to detect the presence of infectious disease antigens and antibodies in pooled samples of multiple people.

There are two modes of “mixed detection”. One is to sample several people, such as 3 or 5 people and put them into the same sampling tube.

The other is to mix samples of the same volume from 3 or 5 people during laboratory testing, also known as “sample mixing”.

From a scientific point of view, the first “mixed sampling” mode will not affect the sensitivity of nucleic acid detection. While the latter mode of mixed detection of samples has a certain impact on the sensitivity of the detection, the degree of impact is controllable.

In order to detect high-risk groups, such as symptomatic patients and close contacts in fever clinics, we still recommend separate sampling.

For screening of low-risk groups, pooled sample test is our first choice.

Is the mixed detection technology reliable?

Is the “five-in-one” and “ten-in-one” mixed mining detection technology reliable?

“The size of the single-collection tube and the mixed-collection tube are different, and the amount of the preservation solution is also different.

Based on the results of a large number of basic experimental research and practical operations in the previous period.

The increase in the volume of the mixed-collection preservation solution has no effect on the detection results of weakly positive specimens.”

In the case of an extremely low positive rate, the 10-in-1 mixed detection technology is very efficient.

The FDA is aware that there is a great interest in performing testing using pooled samples.

This approach increases the number of individuals who can be tested with the same amount of resources.

What are the benefits of mixed nucleic acid detection?

The hybrid detection of nucleic acid has greatly improved the nucleic acid detection capability, reduced the burden of personal testing costs, and did not affect the time for issuing the test report.

The testing time of a single test and mixed test laboratory is the same, but compared with a single test, the mixed test is more suitable for mass and group screening.

In the case of small-scale outbreaks, the use of mixed detection can improve efficiency, play the role of multiple screening, early diagnosis, reduce transmission, and save social costs.

Whether the population is suitable for mixed testing shall be carried out in accordance with the requirements of the provincial and municipal epidemic prevention and control headquarters,

The medical institutions carrying out the testing must follow the technical requirements and standards of the municipal health department.

Which groups recommend the single purchase and single inspection?

It is worth mentioning that single sampling and single inspection are recommended for specific populations.

The above notice specifically mentioned that COVID-19 nucleic acid 10 in 1 and 5 in one mixed detection technology is suitable for large-scale rapid screening of the low-risk populations, and is more suitable when the overall positive rate of population is low (0.1%).

However, for the detection of high-risk groups such as symptomatic patients, close contacts and people in key areas in fever clinics.

Recommended to adopt single sampling and single detection.

What should I pay attention to when doing pooled sample detection?

1. When going to the testing point for nucleic acid testing, wear a mask, and it is best to prepare one or two spare masks.

2. Two hours before the swab test, it is recommended not to eat to avoid vomiting during the test.

3. When waiting for the test, remember to keep a distance of more than one meter between the front and rear personnel to avoid close contact.

4. Whether it is doing swab testing or getting the report, it needs to be certified as one, so be sure to bring ID cards, receipts and other materials, so as to avoid incomplete materials at that time, which will affect the testing and reporting.

What to do before swab test

Posted on 2022年1月19日2022年3月22日 by Dr. Lee

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.

What is a Medical Swab

Posted on 2022年1月5日2022年3月22日 by Dr. Lee

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.

Cell Medical swab

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

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

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

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

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.
