Sterile Foam or Flocked Tipped Applicator

The outbreak of the novel coronavirus pneumonia in 2020 on a global scale has brought significant losses to human society. Viral nucleic acid detection plays a key role in epidemic prevention and control.

As the first step in viral nucleic acid detection, specimen collection is an indispensable link.

The amount of virus collected and released by sampling swabs is directly related to the positive rate of nucleic acid detection. As the gold standard, nucleic acid detection plays an important role in virus detection, and the role of swabs as a sample collection tool should not be underestimated. Among them, throat swabs and nasal swabs are most commonly used, and anal swabs are also used as auxiliary tests.

During the epidemic, researchers from various countries analysed and found that the efficiency of flocking nasal swab sampling and the acquisition of virus samples were the best.

At the same time, in order to solve the problem of the shortage of nasal swabs.

Nasal swabs

The researchers proposed a combined sampling method of oropharyngeal and nasal swabs to achieve the same effect as nasal swabs.

As the main tool for sampling, swabs have important applications in the fields of forensics, clinical medicine, and environmental testing.

Swabs of different materials, such as rayon, foam, polyurethane, polyester, flocked nylon, etc., will have different structures and performance differences and have different collection effects for different specimens such as protein and nucleic acid, which will affect the detection.

The selection of appropriate swabs according to different sampling samples and testing indicators is very important for testing, and the proper use of swabs is also very important for sample collection and the safety of medical staff.

Flocked Swabs and Custom Swab Manufacturing

ISO13485 quality management system for producing disposable sampling swabs, quality standards, and sterile swabs.

Nylon flocking swabs–small nylon fibres to a moulded plastic rod.

This production process significantly increases the surface area of the nylon swab, which is conducive to the adsorption of bacteria and easy release.

Oral Foam Swabs 104mm (with 22mm breakpoint)

The sponge swab is soft in texture and has numerous tiny pores. It has strong adsorption to liquid, can collect more target analytes, increase the number of samples collected, and can release a large number of samples without defibrillation.

How to elute, etc., which will affect the test results. Many factors can affect the swab sampling results.

The cotton swab used to poke the throat or nose during the nucleic acid test of the new crown should be called an aseptic sampling swab, also called a pharyngeal swab. According to different sampling sites, including nasopharyngeal swabs and oropharyngeal swabs.

The swab is in direct contact with the nasopharynx or oropharynx to absorb the secretion sample, then put the head with the secretion into the culture solution, break the handle through the breakpoint, seal the lid and send it for testing.

Nasopharyngeal Sampling Procedure

In this process, the swab involves two links: sampling and elution (release the collected sample into the culture medium). The choice of different materials will affect the efficiency of sampling and release, and also affect the correctness of PCR detection. There are certain requirements for the material of the sampling swab.

PCR TEST

According to different materials, common swabs can be divided into medical cotton swabs, foam swabs and flocking swabs.

Several reports have shown that the sensitivity of medical cotton swabs in collecting respiratory samples is low, and natural fibres such as cotton have strong adsorption to proteins, which is not conducive to the subsequent release in the culture medium.

Generally, cotton swabs also have wooden handles, which may adsorb proteins during storage and interfere with virus detection. In addition, the wooden handle is too hard to break, and can also cause safety problems when sampling.

The US CDC recommends that the swab head material— synthetic fibres. The use of calcium alginate swabs or swabs with wooden shafts may inactivate certain viruses and reduce Accurate substances.

Flu Test Throat Swab China Factory And Manufacturers

Posted on 2022年5月26日2022年5月26日 by Dr. Lee

Influenza requires a throat swab test. Tests can be used to determine whether a patient is infected with the flu virus, and then targeted treatment can be given.

Influenza patients will have symptoms of dry cough, and they will also have dry cough symptoms after being infected with the new coronavirus, so throat swab tests should be performed for patients who have been in contact with people infected with the new coronavirus or who have been to the epidemic area. Patients infected with the new coronavirus generally do not need a throat swab test to determine whether they are infected with the new coronavirus.

Covid Test Flu Throat Swab

The throat swab detection process is as follows: the tested person needs to sit facing the sampler, raise his chin, and open his mouth wide. in special equipment.

These tests include reverse transcription-polymerase chain reaction (RT-PCR), viral culture, and immunofluorescence assays. All we require is that a health care provider swipe the inside of your nose or the back of your throat with a swab and then send the swab for testing. Results may take one to several hours.

Accuracy of throat swabs for influenza.

A throat flocked swab for influenza is more accurate, but there are no authoritative experimental statistics for its specific accuracy.

Throat swab testing for influenza is very fast, economical, and simple, but if the throat swab is negative.

It does not mean that there is no Influenza that may be caused by contamination of specimens, improper sampling of specimens, etc.

And comprehensive judgment should be made in combination with clinical symptoms, epidemiological history, and antigen testing.

When taking a throat swab for influenza, insert the swab completely into the throat from the oral cavity, and moderately wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall with the throat wall and the reddened part of the palatine tonsil as the centre. But avoid touching the tongue. Then remove the test strip. Insert the sampled swab into the solution in the sample extraction tube

So that the specimen is dissolved in the solution as much as possible, and the results can be observed within 15 to 20 minutes.

After more than 30 minutes, the displayed results are usually not clinically meaningful.

If there are two red lines or three red lines in the patient, it means that the throat swab test for influenza is positive.

And there are two red lines, which usually means that there is influenza A or B. If it is three red lines, it means that it is a mixed infection of influenza A and B.

If only one red line appears, the throat swab is negative.

If the reaction line does not appear, the test is invalid, and it is recommended to use a new test card to test again.

Is it a cold or the flu? How to distinguish?

1. Influenza: fast and furious,

If you feel like you’ve been hit by a truck, you might have the flu. Symptoms such as sore throat, fever, headache, muscle aches, congestion and cough can come on suddenly. Colds are usually less intense and include a runny or stuffy nose. The flu gets better in 2 to 5 days, but you may feel the discomfort for a week or more. Colds come on slowly and last up to 10 days.

2. Fever: Usually means the flu

While some people have a mild fever when they catch a cold, most do not. If you have the flu, your body temperature may reach 38-40°C. The flu tends to be higher in children, and children may also be more likely to develop a fever.

3. Flu: Fatigue can last for weeks

You may start to feel very tired and sore. Fatigue and weakness can last up to 3 weeks, and even longer in older people and people with long-term (chronic) illnesses or weakened immune systems. Colds are self-limiting and you usually get better within a few days, usually 1 week to 10 days.

4. Cold and flu: Both can cause headaches

Like other symptoms caused by a cold, headaches that accompany a cold are still milder than those caused by the flu.

5. Cough: Both colds and flu can cause

Colds and flu are respiratory illnesses that both affect your airways, so both can cause a cough.

Pneumonia is a lung infection that can be a complication of the flu. If you have a persistent cough, fever higher than 38°C, chills, difficulty breathing, shortness of breath or chest pain, please seek medical attention in time.

6. Earache: Maybe from a cold or the flu

Congestion from either disease can raise the pressure in your ears. This affects the Eustachian tube, where the larynx and middle ear communicate. It may cause dull ear pain, hearing loss, and a “popping” feeling in the ears. These symptoms will disappear as the disease improves.

If other symptoms get better and the earache persists or you experience sudden, intense pain, see your doctor. You may have an ear infection that needs treatment.

7. Colds: Usually starts with a sore throat

These early symptoms tend to last 1 to 2 days, and a runny nose and nasal congestion are also common. A sore throat also accompanies the flu, but if it’s the flu, you may feel tired and have other symptoms right away.

8. Stuffy nose: Could mean a cold

Simple nasal congestion without fever and general tiredness tends to lead to a cold, although many flu sufferers also say they have nasal congestion and sneezing.

Both colds and flu can cause sinus infections. In addition to a thick yellow or green snot, a sinus infection can also cause headaches and pain in the forehead, cheeks, and bridge of the nose. Sudden head movements or strains can make the pain worse.

9. Flu throat swabs can quickly identify the flu

Flu Test Throat Swab China Factory And Manufacturers

ABOUT US

The quickest way to find out about your illness is to go to the hospital for a checkup.

A nasal or throat swab can usually tell you if you have the flu virus in 30 minutes or less. If a test shows you have the flu and your symptoms started within the past 48 hours, your doctor may recommend antiviral medication to help you recover faster.

10. Influenza: start antiviral drugs as soon as possible

These medications can give you relief and shorten your condition within 1 to 2 days, especially if you start taking them within 2 days of getting sick. Over-the-counter medications can also relieve symptoms such as coughing and congestion. Read labels and directions carefully so you know what the medicines do and how to use them.

11. Colds: Over-the-counter medications can ease symptoms

12. Hand washing is key

Washing your hands is very important to protect yourself and not spread the flu to others. Wash your hands with soap and warm water, preferably the six-step method. Alcohol-based hand sanitizers are also effective.

Wash your face frequently during cold and flu season, especially after coughing, sneezing, or having a runny nose. What if I can’t find a tissue? Face your elbow when sneezing or coughing instead of covering your mouth with your hand.

13. Get vaccinated

There is now a flu vaccine that protects against the flu, and it’s made from a protein from the previous year’s flu cases. It helps your body prepare to recognize and fight when you’re exposed to the virus again. Note: The flu shot won’t give you the flu!

The flu shot is very important for children over 6 months of age, pregnant women, adults 50 years and older, and people with long-term (chronic) illnesses or weakened immune systems.

What is viral transport medium ?

Posted on 2022年5月6日2022年5月6日 by Dr. Lee

Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.

Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.

We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.

What is a virus?

Viruses are microorganisms whose structure is very simple.

There is no way to complete the process of self-replication.

They need the help of host cells and the nutrition of the host to complete virus replication.

The virus can infect humans as well as many other animals.

Influenza viruses such as common infectious diseases are usually RNA viruses.

There are many common viruses that cause human infection, which can cause respiratory diseases, such as cold virus, influenza virus, HIV and influenza A virus.

Since it has no cellular structure of its own, the virus itself cannot replicate.

But invades the gene into the host cell and replicates the new virus with the help of the latter’s replication system.

In conclusion, viruses are diverse and can cause damage to multiple parts of the body. “

After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab ( flocking swab ) will be put into the preservation solution ( viral transport media ) for preservation and transportation.

What is the viral transport medium used for?

PCR test

The inactivated viral transport medium can perform protein denaturation on fresh clinical virus specimens to inactivate the virus. Prevent secondary infection and ensure the safety of transportation and testing personnel. The inactivated samples can be used with a variety of virus extraction kits.

The nucleic acid extraction instrument can quickly extract nucleic acids.

At the same time, with the respiratory pathogen PCR detection kit (VTM Kits) to achieve rapid detection. The specificity and sensitivity are not affected.

Virus preservation solution has many functions:

1. The operation is simple, and the liquid contains ingredients that can denature proteins, thereby inactivating the virus;

2. Contains inhibitors to protect the stability of viral nucleic acid to a greater extent and greatly improve the nucleic acid extraction rate;

3. Stored at room temperature for 12 months before sampling.

The airtightness is good, which is convenient for storage and transportation and saves transportation costs.

Cell medical (Dongguan) Co., Ltd.

Viral transport media include inactivated and non-inactivated viral transport media.

Contains Hank‘s Liquid, Potassium Chloride, Magnesium Chloride, Calcium Chloride, BSA, etc. The combination of various antibiotics has antibacterial and antifungal effects. Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus. Making it difficult to decompose and ensuring the integrity of the virus; Hank’s buffer The neutral environment constructed by the agent helps to increase the survival time and infection stability of the virus.

What is viral transport medium?

Nasopharyngeal Swab

Inactivated and non-inactivated virus preservation solutions: usually used for the collection and transportation of clinical influenza, avian influenza, hand, foot and mouth virus, measles and other virus specimens, as well as specimens such as mycoplasma, ureaplasma, chlamydia, etc.

1. For monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments.

It is suitable for a sampling influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses.

2. To transport nasopharyngeal flocked swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for PCR extraction and detection.

3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.

What kind of virus sampling tube do you know? Does the following look like what you know? The following is introduced to you by Disposable Virus Sampling Tube Manufacturers — Cell medical (Dongguan) Co., Ltd.

What is Virus Sampling Tube? When should the virus preservation solution be used?

Disposable Virus Sampling Tube Kits

Virus transport medium, virus preservation solution: a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling.

Generally, in the process of nucleic acid detection, we cannot directly conduct nucleic acid PCR experiments at the sample collection site.

If we need to check the samples collected by the flocked swab, we need to add the virus preservation solution.

Why use a virus sampling tube?

First of all, we have to understand what is a virus? Why does it need a virus sampling tube?

virus sampling tube

What is a virus?

Virus: a non-cellular form composed of nucleic acid molecules and proteins.

It lives on parasitic hosts and is an organic species between living and non-living bodies.

It is one end of DNA or RNA wrapped in a protective shell.

Through the mechanism of infection, these simple organisms can use the host’s cellular system to replicate themselves but are unable to grow and replicate independently.

Viruses can infect almost all living organisms with cellular structures.

Virus detection is different from conventional biochemical detection.

The virus itself is a simple microorganism and must be parasitic in living cells.

After sampling, when the virus leaves the host cell, its protein shell and nucleic acid degrade rapidly in the sampling tube.

So that the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, which is likely to cause false negatives.

A virus delivery medium (virus sampling tube), a general-purpose sampling product: for sampling various virus samples, chlamydia samples, and ureaplasma samples.

Short-term storage and transportation at 2-8°C, and -80°C refrigerator or liquid nitrogen Long-term preservation in the environment.

1. For monitoring and sampling infectious pathogenic microorganisms by disease control departments and clinical departments.

Suitable for influenza virus (common influenza, highly pathogenic avian influenza, influenza A H1N1 virus, etc.), hand, foot and mouth virus and other types of virus sampling. It is also used for sampling Mycoplasma, Chlamydia, Ureaplasma, etc.

2. To transport nasopharyngeal swab specimens or tissue specimens from specific parts from the sampling site to the testing laboratory for extraction and testing.

3. Preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture.

4. For short-term storage and transportation of virus samples at 2-8°C and long-term storage in a -80°C refrigerators or liquid nitrogen environments.

There are two types of virus preservation solutions: inactivated and non-inactivated

The inactivated virus preservation solution is mainly a virus lysis type preservation solution improved by nucleic acid extraction lysis solution, which is added with a high concentration of lysis salt, which can quickly and efficiently deactivate the virus protein in the sample to be tested and can effectively prevent infection.

At the same time, it also contains an RNase enzyme inhibitor, which can protect virus nucleic acid from degradation.

As long as the subsequent NT-PCR experiment can detect the nucleic acid of the virus, we can diagnose it.

Stored at room temperature for a relatively long time.

The non-inactivated preservation solution is mainly a virus maintenance solution that is improved on the basis of the transport medium.

It can retain the protein coat of the virus and the viral nucleic acid DNA or RNA at the same time so that the virus has the integrity of the protein epitope and nucleic acid in vitro.

Of course, there is also a certain risk of infectivity when the operation is wrong.

It is necessary to keep a strictly low temperature for long-term storage after sampling.

No matter what kind of virus preservation solution it is, we must test it as soon as possible after sampling or keep it strictly at a low temperature to ensure that the detection is accurate.

Due to the rapid reproduction and mutation of the virus, the virus preservation solution plays a crucial role in maintaining the stability of the virus sample.

Manufacturers CellMedical Virus Sampling Tube Kits Advantages

1. Add protein-stabilizing components such as BSA to the sampling solution to reduce the speed of virus decomposition and greatly improve the positive rate of virus isolation.
2. It is stable at room temperature and can keep its activity within 1 year.
3. Gentamicin replaces penicillin to avoid allergic reactions;

4. Using flocked swabs, the sample has a higher collection rate and release rate;

6. Thickening and anti-leakage design to ensure that the sample does not leak, in line with WHO regulations and biosafety regulations.

Viral Transport Medium With Swab

Posted on 2022年4月14日2022年4月14日 by Dr. Lee

Viral transport medium with swab

The COVID-19 outbreak is expected to have a significant impact on the tedious market for swabs and virus transport media owing to the increasing patient demand for infection diagnosis.

Flocked Swab and viral transport media are expected to grow due to intensive testing of COVID-19 in research institutions and laboratories.

Rising research and development activities to produce COVID-19 vaccines are expected to drive market growth during the pandemic.

The rising number of COVID-19 cases in the global population is expected to drive market growth.

The need to develop vaccines and early diagnostics to treat infections is expected to boost the market growth.

Manufacturing of Viral Transport Medium

Virus sampling tubes are medical device products. The virus sampling tube consists of a sampling flocking swab, virus transport medium and outer packaging. Since there is no unified national standard or industry standard, the products of various manufacturers vary greatly.

CellMedical manufactures viral transport media (VTM) following WHO and CDC recommendations, with or without swabs.

Flocked swab+tube with Viral transport medium

1. Sampling swab:

Virus sample collection flocked swab

The specimen collection swab directly contacts the sampling site, and the material of the sampling head is closely related to the subsequent detection.

　　Synthetic fibres such as PE synthetic fibers, polyester fibres, polypropylene fibers, and rayon fibres should be used for the manufacture of sampling swab tips.

　　(1) Natural fibers such as cotton are not recommended

　　Because the fiber of cotton has strong adsorption of protein, it is not easy to be eluted into the subsequent preservation solution;

　　(2) Nylon fibers are also not recommended

　　Because nylon fibers (similar to toothbrush heads) have poor water absorption, the sampling volume is insufficient and the detection rate is affected.

　(3) Do not use calcium alginate sponges or wooden stick swabs (including bamboo sticks) for the head of the sampling swab.

　　Because the broken wooden sticks or bamboo sticks containing calcium alginate and wooden components will also adsorb proteins after being soaked in the preservation solution, and even have an inhibitory effect on the subsequent PCR reaction.

Features of CellMedical Flocked Swabs:

1. Has extraordinary adsorption energy.

2. It has a release rate of more than 95% for the collected specimens, thus ensuring a high degree of reliability of the results;

3. There is a unique breakable design on the plastic rod, which is convenient for specimen transportation;

4. Sterilized by ethylene oxide or irradiation, individually packaged;

Nasopharyngeal and oropharyngeal swabs. learn more

2. Virus preservation solution (virus transport medium): There are mainly two kinds of virus preservation solutions widely used in the market, one is a virus maintenance solution improved based on the transport medium, and the other is an improved nucleic acid extraction lysate. Preservation solution.

3. Virus sampling tube: The material of the storage tube should be selected carefully. Some data suggest that polypropylene (Polypropylene) is related to the adsorption of nucleic acids, especially at high tension ion concentration, polyethylene plastic (Polyethylene) than polypropylene (Polypropylene) Easier to grab DNA/RNA. In addition, when using breakable swabs, the storage tube should try to choose a container with a height of more than 8 cm to prevent the contents from splashing and contaminating when the swab is broken.

Virus Sampling Tube

4. Water for production of preservation solution: Ultrapure water used for the production of preservation solution should be filtered by an ultrafiltration membrane with a molecular weight of 13,000 to ensure the removal of biologically derived polymer impurities, such as RNase, DNase and endotoxin, and ordinary purification is not recommended. water or distilled water.

About the use of virus sampling tubes

Sampling using virus sampling tubes is mainly divided into oropharyngeal sampling and nasopharyngeal sampling:

1. Oropharyngeal swab sampling:

first press the tongue with a tongue depressor, then insert the head of the sampling swab into the throat to wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall, and wipe the posterior pharyngeal wall with mild force, avoiding touching the tongue department.

2. Nasopharyngeal swab sampling:

measure the distance from the tip of the nose to the earlobe with a swab and mark it with your fingers, insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be inserted at least half the length from the earlobe to the tip of the nose. Leave the swab in the nose for 15-30 seconds, swirl gently 3-5 times, and withdraw the swab.

It is not difficult to see from the method of use, whether it is an oropharyngeal swab or a nasopharyngeal swab, sampling is a technical task, which is difficult and easy to contaminate. The quality of the collected samples is directly related to the subsequent testing. If the viral load of the collected samples Low, easy to cause false negatives, difficult to diagnose.

Most of the samples recommended by the kits currently on the market are oropharyngeal swabs or nasopharyngeal swabs and bronchoalveolar lavage fluid. This can greatly reduce the difficulty of the samplers’ work. After all, it is not difficult to collect venous blood samples, and like the detection of hepatitis C RNA, about 5 ml of EDTA anticoagulated blood samples are separated into plasma, and the extracted and purified RNA can fully meet the needs of PCR detection.

Preservation solution features:

Our independent research and development and production, unique cell preservation technology, can be stored at room temperature for more than 3 years after sampling! No need to refrigerate, store and transport at room temperature.

What is A Covid-19 NP Swab?

Posted on 2022年4月12日2022年4月12日 by Dr. Lee

The COVID-19 Swab test is an important part of the anti-epidemic work, and it is extremely important to standardize the operation of sampling techniques.

All sampling operations must be standardized. In order to provide a strong guarantee for the accurate reporting of subsequent nucleic acid testing.

Nasopharyngeal (NP) swabs are the primary sample type for respiratory molecular pathogen testing.

During the 2019 novel coronavirus infectious disease (COVID) pandemic, NP swabs became central to the detection of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2).

Unfortunately, NP swab collection can be very uncomfortable for some patients.

Because when collecting nasal swabs, a relatively long flocked swab, is directly inserted into the nasal cavity of the person being collected.

However, nasal swabs will not cause pain if the operator is appropriate, but some people with sensitive noses or diseases may experience mild discomfort.

Np swab covid test meaning?

Np swab is the nasopharyngeal swab test, which refers to a relatively conventional method for detecting viruses.

Nasal swab testing mainly involves inserting a relatively long sterile flocked swab into the patient’s nasal cavity.

It was then collecting secretions from the nasopharynx through the nasal cavity.

And then testing these secretions in various aspects, such as bacterial culture And drug sensitivity test to determine the source of infection and the type of microorganisms.

Symptomatic treatment according to the test results, and a drug sensitivity test can also be used to determine which drug is more sensitive.

Use the more sensitive drug for treatment.

What should medical staff pay attention to when collecting nasopharyngeal swabs?

All healthcare professionals performing nasopharyngeal swab tests must wear the recommended personal protective equipment (PPE), which should include N95 masks, disposable caps, goggles, protective clothing, latex gloves, and shoe covers.

Nasopharyngeal flocked swabs: performed with the patient sitting upright with the head in an upright position.

What is A Covid-19 NP Swab?

The subject needs to tilt his head back.

Nasopharyngeal swabs are not along the nostrils, but perpendicular to the face, entering from the nasal passages.

When collecting, do not enter violently when encountering resistance or the subject feels obvious pain.

When taking nasopharyngeal sampling, the operator can stand behind the subject and does not need to look directly at the nasal cavity.

In addition, there is basically no gag reflex, the tolerance is good, and the risk of exposure is relatively low.

After sampling, the individual tested may have a sneeze reflex, immediately use an elbow or a tissue.

A small number of subjects may have a little nosebleed after sampling, which can usually be stopped on their own.

When taking a nasopharyngeal swab, it can stay in the nasopharynx for a longer time in order to obtain a more adequate sample.

Studies have shown that the positive rate of nasal swab samples is higher than that of throat swab samples, that is, the efficiency of nasal swabs for virus swab detection is higher than that of throat swabs.

What can a nasopharyngeal swab detect?

Used for nasopharyngeal sampling for respiratory viruses such as influenza, swine flu, bird flu, and hand, foot and mouth.

A nasopharyngeal culture

The reasons for false negatives

1. Patient: The virus content may be too low. The nucleic acid swab detection reagent has certain requirements for the virus presence in the infected person. If the virus is too low, existing methods may not detect it.

The onset of new coronary pneumonia patients will go through a process from asymptomatic after infection, to mild symptoms, to severe symptoms.

2. Collection of specimens: false negatives cannot be completely avoided.

Many experts have concluded from practical work that the positive rate of sputum and bronchoalveolar lavage fluid samples collected from the lower respiratory tract is higher than that of oro-nasopharyngeal swabs from the upper respiratory tract; the positive rate of nasopharyngeal swab samples is higher than the Oropharyngeal swab.

Improper collection site, for example, when collecting oropharyngeal swabs, the depth of the collection is not enough;

Nasopharyngeal swabs are not enough deep into the nasal cavity, etc., and most of the collected cells may not contain viruses, which may cause false negatives.

3. Detection reagents: At present, the quality of the reagents on the market may vary.

4. In addition to the test reagents themselves, laboratory specifications will also have an important impact on the test results. Specimen transportation and storage conditions, standardized operations in clinical laboratories, result interpretation and quality control are all key factors to ensure the accuracy and reliability of test results.

Prevent false negatives

Incorrectly performed nasopharyngeal swabs may lead to a greater likelihood of patients receiving false-negative test results.

False-negative results are an important issue to address, as these results can cause patients who are positive for some diseases to unknowingly transmit highly contagious diseases, especially COVID-19, too many others.

Therefore, adequate training of testers on how to perform nasopharyngeal swab tests reliably is critical. Use high-quality detection reagents. learn more.

Nasopharyngeal swabs are suitable for collecting and transporting virus specimens such as covid-19, clinical influenza, avian influenza, hand, foot and mouth disease, and measles, as well as specimens of chlamydia and mycoplasma.

In order to respond to this round of the epidemic, stop the spread of the virus and reduce the risk of infection.

At present, we have successively carried out multiple rounds of swab testing for the new coronavirus.

Why are oropharyngeal swabs and nasopharyngeal swabs performed in covid swab testing?

covid flocked swab

Nasopharyngeal swab refers to the collection of secretions from the throat or nose of a patient with a specialized sterile flocked swab.

We generally use nasopharyngeal swabs to detect viral nucleic acids, viral antigens, and bacterial cultures.

The collection site of the oropharyngeal swab should be the pharynx and tonsils.

The basic steps of collecting the pharyngeal swab are to tilt the patient’s head back, open the mouth wide, and remove the secretions on the surface of the nasal cavity.

The sampler fixed the tongue with a tongue depressor and used polyester or calcium alginate test paper to cross the base of the tongue.

Wiped the posterior pharyngeal wall and the lateral wall of the tonsillar recess 3-to 5 times to collect mucosal cells.

Remove the swab gently, avoiding contact with the tongue, uvula, oral mucosa, and saliva, and insert the swab back into the sampling device or a suitable transport device.

Nasopharynx swab vs oropharyngeal swab

The main difference between the two lies in the sampling method and sampling location.

The detection rate and accuracy of nasopharyngeal swabs are higher than those of oropharyngeal swabs.

Still, nasopharyngeal swabs are more complicated and difficult to operate, and people with nasal diseases。

Such as rhinitis and nasal polyps will not easily adapt, Bleeding may occur during the collection process, so the collection speed is slow.

Compared with nasopharyngeal swabs, oropharyngeal swabs are fast, simple and easy to collect.

And the detection rate can meet the requirements.

Therefore, oropharyngeal swabs are often used in large-scale screening.

For key groups or middle- and high-risk groups.

Required to collect nasopharyngeal swabs, or even stool and blood samples.

In addition to nasopharyngeal swabs and oropharyngeal swabs.

There are also detection methods such as serum, anal swabs, deep cough sputum, nasopharyngeal or respiratory tract extracts, and bronchial lavage fluid.

In general, the method of sample collection will be determined according to different populations and different needs.

Viral transport medium is a protective liquid medium added to the virus sampling tube to protect the samples after nasopharyngeal swab sampling and is usually called virus preservation solution in China.

Usually, in nucleic acid testing (PCR swab test), we cannot perform nucleic acid PCR directly at the sample collection site.

We need to add virus preservation solution (VTM) to the samples collected by swab for transfer check.
