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

1. Adopt internationally accepted paper-plastic packaging which is convenient for sterilization.

2. Gamma ray sterilization to ensure sterility.

3. Each set in the large packing box is individually packaged for easy use.

4. Different preservation solutions are selected for different types of specimens.

Advantage

1. The unique spray-type implanting nylon fiber technology increases the collection and release of specimens.

2. The swab has a total length of 14.5cm, and the plastic rod has a unique breakable design.

3. The fluffy texture can collect more target analytes.

4. There is no residual amount of specimens, which speeds up the processing of specimens.

5. The swab is sterilized and individually packaged.

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

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.

Nasopharyngeal swab sampling process

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.

Advantages of CM flocked swab

Brief description: it has outstanding sample collection and release ability, can quickly adsorb micro samples, and has high release efficiency

In order to improve the collection of samples, there are different types of flocking swabs, such as pharyngeal swabs, gene detection swabs, forensic DNA detection swabs, gynecological cervical sampling swabs, microbial sampling swabs, etc. all flocking sampling swabs have clear advantages in many application fields.

CM flocking swab series

CM flocking swab series

Advantage

1.Ergonomic and anatomical design;

In order to improve the comfort of patients and the efficiency of cell sample collection.

2. Improve detection inspiration;

The flocking swab proved that it can quickly elute > 95% of the original samples, and easily improve the detection sensitivity.

3. Easy to collect, break, and then transport;

Open the package, collect the cell sample, and then break the broken point part of the swab into the delivery medium or the test tube provided.

4. Certified free of inhibitors and interference;

The sampling swabs were certified to be free of ribonuclease (RNase), deoxyribonuclease (DNase), human deoxyribonucleic acid, and no PCR inhibitors.

Our flocking swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

COVID-19 nucleic acid detection specimens

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.

What is COVID-19 nucleic acid testing using throat swabs?

Oropharyngeal Sampling

Oropharyngeal Sampling

Because COVID-19 is mainly spread through droplets and contacts, plus the ACE2 receptor necessary for COVID-19 invasion in the respiratory tract, the respiratory tract of the infected person is the main gateway for COVID-19 invasion.

How to pharyngeal swab sampling ?

1. Tear off the outer package of the sampling swab and take out the sampling swab;

2. Expose the throat and press the tongue down with a tongue depressor if necessary;

3. Take out the sterile swab, gently and quickly wipe bilateral pharyngeal tonsils and posterior pharyngeal wall for 3 times, and put the swab head into the preservation solution,

4. Buckle and fold the tail of the swab at the mouth of the storage tube, discard the tail, tighten and cover the tube cap,

5. Check the patient’s name again after sampling;

6. Put it into a sealed bag and a special transfer box, and quickly send the samples to the laboratory for inspection.
