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.
