gg/igm double antibody is 15 minutes out of the accuracy of more than 90% or even up to 98%COVID 19 diagnostic kit is used for the qualitative detection of new coronavirus (2019-nCoV) antibodies in human whole blood, serum and plasma. Coronavirus (CoV) belongs to the order Nestivirus, Coronaviridae, and divided into three genera: �±, �², and �³. The alpha and beta gene are only pathogenic to mammals. The gamma gene mainly causes bird infections. CoV is mainly transmitted through direct contact with secretions or through aerosols and droplets. There is also evidence that it can be transmitted through the fecal-oral route. There have been seven types of human coronavirus (HCoCoV and 2019-nCoV), which are important pathogens of human respiratory tract infection.Among them, the new coronavirus (2019-nCoV) was found for 2019 cases of viral pneumonia in Wuhan. The clinical manifestations are systemic symptoms such as fever, fatigue, dry cough, dyspnea, which can quickly develop into severe pneumonia, respiratory failure, acute Respiratory distress syndrome, toxic shock, multiple organ failure, severe acid-base metabolism disorders and even life-threatening. 2019-nCoV Antibody Diagnostic Kit uses the principle of immunochromatographic method to qualitative detect the coronavirus (2019-nCoV) antibody in human whole blood, serum and plasma. It is used for clinical diagnosis of primary infection or secondary infection of new type of coronavirus infection pneumonia.
When the epidemic is waiting for an opportunity again, to quickly control the spread of the virus, nucleic acid testing has become the only way to go, and it has also attracted attention from all walks of life. However, there are many factors that affect the results of nucleic acid testing, including sample collection location, collection method, storage and transportation process, nucleic acid extraction operation, and so on. Among them, the stability of the sample is a key link. How to quickly inactivate the virus and protect the viral nucleic acid from being degraded, maintaining the stability of the virus sample storage solution has become a top priority. Step 1: Break the shell and eliminate the "combat power" Like other RNA viruses, the results of the new coronavirus are simply composed of a protein shell wrapped in single-stranded nucleic acid-RNA. We can simply think of the RNA of the virus as the "brain" that gives orders, and the protein is the "limbs" that execute orders. The new coronavirus infects the human body and reproduces and causes symptoms. This process is mainly completed by the biologically active protein structure outside the virus. The inactivated virus preservation solution is mainly the virus modified by the nucleic acid extraction lysis solution; it is a powerful protein denaturant that can quickly dissolve the protein and cause the virus structure to be broken. When the clinical sample with the new coronavirus is mixed with the preservation solution, the virus in the sample is affected by the lysis solution, and the protein shell is quickly destroyed, and this damage is irreversible. At this time, the virus has lost its evil "minions" and no longer has the ability to infect people, thus ensuring the safety of contacts during sample transportation and processing. Step 2: Inhibit enzyme activity and escort the "ID card" After the shell is lysed, the RNA of the new coronavirus is free in the preservation solution. As a single-stranded macromolecule, the stability of RNA is not as immobile as double-stranded DNA. The RNase that exists everywhere in the natural environment is the culprit that causes RNA to hydrolyze and break. Therefore, it is generally considered that the viral RNA that has lost its outer shell protection is In addition to the inactivated virus storage solution, the virus preservation solution produced by Desheng also has a non-inactivated virus storage solution. It retains 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 a certain risk of infectivity when operating errors. Long-term storage after sampling needs to keep strictly low temperature. Regardless of the virus preservation solution, we need to strictly operate, store or transport in accordance with the requirements when using it.
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.
