Some reports put the accuracy of the New Crown test strips for the virus at around 95%, but clinical observation is needed. As the global battle against the New Crown epidemic continues, scientists are constantly researching New Crown detection methods, including New Crown blood tests, swab tests, and New Crown test strip tests. It has been publicized that the New Crown IgG/IgM antibody colloidal gold rapid test card can be about 95% accurate in detecting the New Crown virus. The result of this test paper shows that if there is a double bar indicates that there may be a new crown infection, but it is not the gold standard, and if there is a single bar indicates that there may not be a new crown infection. At present, China has taken the most nasopharyngeal swabs, pharyngeal swabs to detect the nucleic acid of the new crown virus, and the cost is relatively low, you can go to the hospital to screen for new crowns through these two tests, the accuracy rate is higher.
