New Coronavirus nucleic acid detection steps

1、 The specific operations are as follows

1. Virus sampling:

Take the patient’s saliva sample or nasopharyngeal flocked swab sample, and save the virus sampling tube.Virus preservation solutions commonly used in disposable virus tubes include inactivated and non inactivated types. The following are two models of virus transport medium:

1) Inactivated type: the inactivated virus transport medium characterized by killing the virus and retaining nucleic acid fragments. Application:detect COVID-19, influenza virus, hfmv and influenza A.

2) Non inactivated type: the non inactivated virus transport medium does not contain lysate. It can retain the activity and integrity of pathogens.Application:virus culture and reproduction to make the detection results more accurate.

2. Nucleic acid extraction:

Extract the genetic material from the patient’s sleeping fluid or nasopharyngeal swab sample. If a patient carries a virus, there will be RNA of the virus’s genetic material in the sample. Sampling personnel should pay attention to prevent RNA degradation when extracting RNA. At the same time, the extracted DNA shall be stored at – 20 ℃, and the RNA and DNA requiring long-term storage shall be stored at – 70 ℃ or liquid nitrogen.

3. Reverse transcription synthesis of cDNA:

reverse transcription of RNA in the extract, reverse transcription of RNA into cDNA, reverse transcription of cDNA synthesis reaction, using reverse transcription primers, dNTPs, reverse transcriptase, RNase inhibitor and DTT. Buffer, an appropriate amount of ultrapure water without RNA / DNase and RNA template. We propose to use commercially available RT-PCR one-step reagent for one round amplification of di.

4. PCR amplification reaction (nested PCR amplification method with secondary amplification):

Use specific primers of virus cDNA for PCR amplification in an amplification instrument. Nested PCR amplification using secondary amplification.

5. Result analysis and judgment:

If the DNA band of the virus is amplified, it is determined that the virus exists in the patient; If no DNA band is amplified, it is determined that the sample taken by the disease has no virus.

2、 Experimental precautions:

① We should set up two positive controls and two negative controls for each test. Only when the positive control enlarges the expected fragment, the negative control does not enlarge any fragment, and the results of two parallel samples are consistent.We can determine the nucleic acid positive or negative reaction results.

② Nucleic acid test is positive: if nucleic acid is positive, we should repeatedly collect samples for retest. If the retest result is nucleic acid positive, we can confirm that the sample result is nucleic acid positive. If the retest result is nucleic acid negative, the nucleic acid test result is uncertain.

Facing COVID-19 variation strain. How should we deal with it？

What are the variant strains of COVID-19?

The variation of COVID-19 B.1.621 was first confirmed in Columbia in January this year. The World Health Organization named it Miao strain and recently listed it as a mutant strain that needs attention. Its influence level is lower than that of the delta strain. Preliminary data show that the Miao strain is similar to the beta strain and will weaken the effectiveness of the antibody.

At present, there are four variants defined by who as “needing attention”, including alpha, beta, gamma and delta. And five variants “needing attention”, including ETA, iota, kappa, lambda and mu.

How should we deal with it？

Weightier than Mount Tai, I think the most important thing about this new crown epidemic is: life is above everything else and responsibility is heavier than Mount Tai.

We often ask: where is the value of life? After this epidemic, we answer is: responsibility.

A person and an enterprise must have a sense of responsibility before their life can be valuable. If a person is not responsible and has no sense of responsibility, his life is worthless.

First, Let’s do a good job in personal protection. Don’t worry too much.

As the general public, we can prepare some masks, medical goggles,Rapid Antigen Test Kit,New Coronavirus test kits and so on.We advocate new crown nucleic acid testing at home

Why use flocked swabs？

COVID-19 is New Coronavirus’s variant coronavirus, which can cause pneumonia after human infection. It belongs to an acute respiratory infectious disease, which is highly infectious and generally susceptible to people. It is easy to replicate in the upper respiratory tract of human body. In general, new crown nucleic acids are detected rapidly within 96 hours after infection. Testers can find viruses in the human upper respiratory tract. Experiments show that flocking swab can quickly elute > 95% of the original samples, and easily improve the detection sensitivity.

Application of sampling flocked swabs.

The upper respiratory tract of the human body includes the nasal cavity, pharynx and throat. That is to say, if a person is infected with COVID-19, he can extract the nucleic acid of the virus in the nasal cavity, pharynx and larynx in 96 hours. Therefore, we generally sample these locations when we carry out the rapid detection of new crown nucleic acid.

we distinguish swabs by different sampling positions. For nasal sampling, we become nasopharyngeal flocked swabs; For oral sampling, we become oropharyngeal flocked swabs.

What is the difference between nasopharyngeal swabs and oropharyngeal flocked swabs?

Nasopharyngeal swabs and oropharyngeal swabs differ in material hardness in addition to the differences in sampling sites. The nasopharyngeal swab is generally slender and soft, and can change its shape along the nasal cavity, which is convenient for the sampling personnel to probe into the upper respiratory tract along the nasal cavity. The oropharyngeal swab will be thick and hard.

In terms of comfort, there are also great differences between the two. Since gas exchange is often carried out in the nasal cavity, the swab shall be fully extended to the end of the nasal cavity during sampling to ensure that sufficient concentration of samples are collected.  This usually brings very uncomfortable feeling to the subject, and sometimes even leads to epistaxis.The oropharyngeal swab only needs to collect the pharyngeal sample, and only needs the person to open his mouth for collection. Although it occasionally causes a temporary feeling of nausea, the discomfort will not last too long.

There are also obvious differences between the two in drug loading. Studies have shown that in patients infected with the new crown virus, the amount of drug carried on the nasopharyngeal swab is significantly higher than that on the oropharyngeal swab. In other words, the detection amount of nasopharyngeal swabs is generally higher than that of oropharyngeal swabs.

In addition to nasopharyngeal flocked swabs and oropharyngeal swabs, there are anal swabs. As the name suggests, anal swab is a kind of test for patients with gastrointestinal symptoms. It can effectively improve the detection rate, but it is not widely used because of the inconvenience of sampling.

Attention

After sampling the flocking swab, we should immediately put the swab into the storage tube to avoid polluting the sample.  Then, the subsequent rapid detection process of new crown nucleic acid was carried out. No matter what kind of swab is used, the process of rapid detection of new crown nucleic acid is the same.  The rapid detection of new crown nucleic acid was completed in four independent areas of the laboratory, and the test results were obtained.

1. The unique jet nylon fiber implantation technology increases the collection and release of specimens.

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

3. The villus texture can collect more target analytes.

4. There is no residual specimen, so the specimen processing process can be accelerated.

5. Swabs are sterilized and packaged separately

How to use cm-98000 oral flocked swab

① Tear the sealing paper on the disposable oral swab package, and gently take out the disposable sampling swab from the bag（ Note: the head of disposable oral swab shall not touch other objects other than the inner wall of oral cavity to avoid contamination.)

② . extend the hand-held sampling swab into one side of the oral cavity, from inside to outside at the inner wall mucosa, and then move the swab up and down for 15-20 times. The number can be increased according to the actual situation, with moderate strength. It is appropriate to stick close to the inner wall mucosa of the oral cavity, so as to ensure that the one-time sampling swab head can dip in the exfoliated cells of the oral mucosa everywhere; According to the same method, collect on the other side of the inner wall of the oral cavity.

③ After collection, please take out the disposable sampling swab from the mouth and put it into the sampling tube, push the disposable sampling swab head, put the sampling head into the storage tube, tighten and save it（ Note: too many rotations will lead to dilution or loss of samples. After sampling, make sure that the disposable sampling swab does not touch any other object.)
