Nasal swab test

Posted on 2021年8月25日2021年8月25日 by Dr. Lee

We used pharyngeal swabs to collect samples from nucleic acid samples. They are “nasopharyngeal swab” and “oropharyngeal swab”.

Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth. And nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

Nasopharyngeal swab sampling process

Oropharyngeal flocked swab sampling process

The pharynx includes nasopharynx, oropharynx and pharynx, all of which belong to the field of upper respiratory tract.The sampling methods of nasopharyngeal swab and oropharyngeal swab are different.

PCR test can collect nasopharyngeal swabs, sputum and other lower respiratory tract secretions, blood, feces and other specimens for testing, nucleic acid detection by New Coronavirus.If its specimen nucleic acid is positive, it can clear the virus infection.

New Coronavirus infection mainly invades bronchial epithelial cells and alveolar epithelial cells. Lower respiratory tract specimens, such as sputum and airway extracts, more accurately reflect virus infection.

Advantages of nasal swabs

More specimens can be obtained by staying in the pharynx for a long time, which is also the reason why the positive rate reported in the literature is higher than that of oropharyngeal swabs.

Use steps

1. Tear off the sealing paper on the packaging bag of the oral swab, and suck the inhaled contaminated swab from the swab. Note that the swab head is in contact with other items other than the oral wall and cannot be sucked.

2. Hold the oral swab to stretch out the oral wall, rotate the oral mucosa for 10-15 times, and then up and down 5-10 times, rub it moderately, and it is advisable to put the oral cavity close to the inner mucosa to ensure that the sampling tip sucks the wall everywhere Exfoliated cells from the oral mucosa; follow the same method and collect them on the other side of the oral cavity.

3. After the collection, the oral swab is taken out of the oral test tube, and the sample is natively sampled. The sampling handle with the broken mark is broken, the sampling sampling tube cover tube, and the final extraction is attached to the link between the sampling test tube cover and the tube cover. Dry it in time and send it for inspection.

Matters needing attention

1. Do not touch the sampling head with your hands or other objects.

2. Do not smoke, drink, or eat 30 minutes before sampling.

3. The oral swab is a disposable product and should not be used twice.

4. Do not use if the package is damaged.

Product features

CM Nylon Flocking Swabs have undergone a large number of clinical experiments to show that, compared with ordinary sterile cotton swabs, CM Nylon Flocking Swabs have a better effect on the collection and transportation of clinical microbial specimens. This is especially true for those specimens that cannot be submitted for inspection in time and have been placed for too long.

What is antibody testing

Posted on 2021年8月19日2021年8月19日 by Dr. Lee

What is antibody testing

Before explaining this method, let’s first understand what antibodies are.

The rapid immunoglobulin M (IgM) test paper developed by Chinese academicians is not only a remedy for false negative sampling, but also a method for detecting antibodies.

After the virus invades the body, it likes to kill directly into the cell and hide in it to copy its offspring crazily.

Of course, before entering the cell, B lymphocytes (a kind of white blood cells) find some viruses. B cells are activated and release a large number of antibodies. These antibodies bind to the virus, make the virus lose its ability to invade, and then phagocytes destroy the virus. We call this process humoral immunity.

The antibody is fast and powerful, but the disadvantage is that it can not enter the cell to kill virus. In short, antibodies can reduce the number of viruses in body fluids and prevent more cells from being infected.

There are 5 kinds of antibodies, namely IgM, IgG, IgA, IgD and IgE, with different characteristics and specialties.

When the body is stimulated by COVID-19, IgM will appear in a week or so. Based on this, by detecting whether the IgM in the human body increases significantly, we can indirectly identify whether the human body is infected or not.

How to use CM nasal swab

Nasopharyngeal swab sampling process

1. Please keep the subject’s head still and remove the secretions on the surface of the anterior nostril.

2. Use a swab or other tool to measure the distance from the nostril to the root of the ear and mark it with your fingers.

3. Insert the swab gently and slowly through the nasal cavity (if both nostrils need to be collected, another swab should be used).

4. Swab to the finger mark or stay for several seconds after encountering resistance to absorb secretions (generally stay for 15 ~ 30 seconds, and then rotate gently for 3 times).

5. Gently rotate and take out the swab and place it in the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.

6. Note the information of the tested person and send it to the laboratory for inspection as soon as possible.

COVID-19 nucleic acid detection specimens

Posted on 2021年8月19日2021年8月19日 by Dr. Lee

As the northern hemisphere gradually enters the autumn and winter season, the form of the epidemic is still not so easy to control.In order to further improve the positive rate of nucleic acid detection, we will show you the collection methods and notes of nasopharyngeal swabs with simple graphics and pictures.

The biggest difference between nasopharynx swab and oropharyngeal swab is that the sampling position is different. That is, oropharynx and nasopharynx. In clinical trials, the positive rate of nasopharynx is relatively higher than that of oropharynx, but the operation requirements of nasopharynx sampling are relatively high and the action should be relatively gentle. In order to improve the positive rate, these patients may take nasopharyngeal swabs again. Comprehensive judgment can improve the diagnostic rate.
