The SARS-CoV-2 detection kit uses colloidal gold immunochromatography for qualitative detection of nucleocapsid antigen of SARS-CoV-2 in human nasal vestibular swabs or oral and salivary swabs.It does not rely on professional equipment, nor does it require the operator to receive professional training. Just follow the product instruction manual to complete the rapid qualitative test of Novel Coronavirus.However, it should be noted that due to technical limitations, accidental factors during the production, storage and transportation of the product, as well as uncertainties such as the operator's operation method, the test can only provide preliminary test results and cannot be used as the sole basis for disease treatment or other health management decisions.The positive results indicate the presence of viral antigens, but do not rule out bacterial infection or co-infection with other viruses.Negative results also do not rule out SARS-CoV-2 infection. Users should take into account their recent contact with a confirmed patient and any clinical signs or symptoms consistent with COVID-19, and visit their local health care provider for a more professional diagnosis if necessary.

Technical advantages:

The product was developed based on colloidal gold immunochromatography to detect the presence or absence of specific proteins on the nucleocapsid of SARS-CoV-2.We put with SARS - CoV - 2 special nuclear capsid protein of specific binding of antibody to strip fixed in the membrane, colloidal gold labeling reagent adsorption in combination with mat, when waiting for inspection sample added to the sample at the end of the strip after the mat, by capillary action to move forward, the combination of dissolved after the mat of colloidal gold labeling reagent reaction, then move to a fixed area of antibody, waiting for inspection and jinbiao reagent combination and combined with the particularity of the interception, gathered in the test, can be observed by naked eye color results.It possess simple, fast, accurate and pollution-free.
