With the recurrence of asymptomatic, nucleic acid testing cannot be stopped for a moment. This is not only a protection for everyone, but also a protection for yourself. Speaking of nucleic acid testing, we have to bring up our virus sampling tube again. Its choice also plays a key role. Why use a virus sampling tube? Virus detection is different from conventional biochemical detection. The virus itself is a simple microorganism that must be parasitic in living cells. After sampling, the virus leaves the host cell, and its protein shell and nucleic acid will be quickly degraded in the sampling tube, so the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, and it is easy to cause false negatives. What are the requirements for an excellent virus sampling tube? 1. In terms of sample effectiveness: The non-inactivated virus preservation solution must maintain the activity of the pathogen's infectious agent. Preferably, it can preserve the activity of the virus at room temperature. The inactivated virus preservation solution needs to inactivate the virus but maintain the nucleic acid of the virus to meet the time from sample sampling to laboratory testing. It is necessary to limit and prevent the reproduction of symbiotic microorganisms to ensure the reliability of diagnostic tests. 2. In terms of safety: Because the virus sampling tubes are basically all infectious substances, and some are highly pathogenic infectious substances, the requirements for packaging containers are very strict, and they need to meet safety and ensure that liquids do not leak during transportation. . So what is the virus preservation solution? Under what circumstances do I need to use a virus preservation solution? The virus preservation solution is a protective liquid medium added to the virus sampling tube to protect the sample after the nasopharyngeal swab is sampled. Normally, nucleic acid PCR cannot be directly performed at the sample collection site during nucleic acid detection. If the sample collected by the swab needs to be transferred and transported, it is necessary to add a virus preservation solution. Why is the virus preservation solution divided into inactivated and non-inactivated? After the virus samples are collected, there is usually no way to test in time at the sample sampling site, so the collected virus swab samples need to be transported, and the virus itself will be quickly lysed outside the body and affect subsequent testing, so when storing and transporting , You need to add a virus preservation solution. For different detection purposes, you need to use different virus preservation solutions and different virus detection experimental conditions, so it is divided into two types of preservation solutions, inactivated and non-inactivated. There are no other microorganisms, causing the virus to decompose after sampling or other influences causing false detections.

Choice of nasopharyngeal swab: The main indicators of clinical evaluation of swab performance are the absorption capacity and release capacity of the swab to the target sample at the sampling site. Nylon flocking swabs are made of fine nylon fibers adhered to a plastic rod. Compared with traditional cotton swabs, the adsorption surface is significantly larger, which is conducive to the adhesion and release of pathogenic microorganisms. The ability of nylon flocking swabs and traditional rayon cotton swabs to recover and release known microbial inoculums (spiked samples) confirms that nylon flocking swabs have the ability to release cells, microorganisms, viruses and other microorganisms Significant advantages. Compared with traditional rayon cotton, nylon flocking swabs or foam swabs have a significant advantage in the virus recovery rate in the screening of nasal cavity carrying MRSA virus. For the choice of virus preservation solution: non-inactivated preservation solution and inactivated preservation solution.
The current test kit is based on specific antibody antigen reaction and immunoassay technique. The test card contains a gold labeled novel coronavirus N protein monoclonal antibody p re coated on the binding pad and a paired novel coronavirus N protein monoclonal antibodies fixed in the test line (T) and corresponding antibodies in the quality control line (C). During the test, the N protein in the specimen binds to the gold-labeled nove lcoronavirus N protein antibody pre-coated on the binding pad, and the conjugate moves upward under the capillary effect, and then is trapped by N protein monoclonal antibody conjugate fixed in the Test Line (T). The higher the N protein content in the specimen, the more conjugates are trapped, and the darker the color of the Test Line (T). If there is no novel coronavirus in the specimen or the virus content is below the detection limit, no colour appears in the Test Line (T). A purple red band will app ear in the Control Line (C) regardless of whether there is a virus in the specimen. The purple red band that appears in the Control Line (C) is the criteria for determining whether there is enough specimen and whether the chromatography process is normal.
The product is based on the principle of antigen-antibody reaction and immunoassay technique. The test device contains colloidal gold labeled SARS-CoV-2 recombinant protein, mouse-anti human IgG antibody immobilized in G test area, mouse-anti human IgM antibody immobilized in M test area and the corresponding antibody in quality control area (C). During the test, when the SARS-CoV-2 IgM antibody level in the sample is at or above the limit of detection of the test, the SARS-CoV-2 IgM antibody in the sample binds to the colloidal gold labeled SARS-CoV-2 recombinant protein which is pre-coated on a gold label pad. The conjugates migrate upward through capillary effect and would be captured by mouse-anti human IgM antibody immobilized in M test area subsequently and this produces a purple-red band appears in the M test area. When the SARS-CoV-2 IgG antibody level in the sample is at or above the limit of detection of the test, the SARS-CoV-2 IgG antibody in the sample binds to the colloidal gold labeled SARS-CoV-2 recombinant protein which is pre-coated on a gold label pad. Theconjugates migrate upward through capillary effect and would be captured by mouse-anti human IgG antibody immobilized in G test area subsequently and this produces a purple-red band appears in the G test area. If it is a negative sample, there is not a purple-red band appeared in the M and G test area. Regardless of the presence or absence of the SARS-CoV-2 antibody in the sample, a purple-red band will appear in the quality control area (C). The purple-red band in the quality control area (C) is a criterion for judging whether there is enough sample and whether the chromatography process is normal. It also serves as the internal control standard for reagents.
