2019-nCoV IgG/IgM Antibody Determination Kit (Fluorescence Immunochromatographic Assay) is an in vitro diagnostic test kit. The test kit is intended for use as an aid in identifying individuals with an adaptive immune response to 2019-nCoV, indicating recent or prior infection. This test kit should not be used to diagnose or exclude acute 2019-nCoV infection. At this time, it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity.
