INTENDED USE The Finecare™ 2019-nCoV RBD Antibody Test is a fluorescence immunoassay used along with Finecare™ FIA Meters for qualitative and semi-quantitative detection of spike receptor-binding domain (RBD) antibodies of novel coronaviruses (2019-nCoV) in human fingerstick whole blood, venipuncture whole blood, serum or plasma specimen. The 2019-nCoV RBD antibodies are protective antibody produced by the human body after inoculation with 2019-nCoV vaccine or infection with 2019-nCoV. The test is intended as an aid to assess the adaptive humoral immune response to the 2019-nCoV RBD protein. STORAGE AND STABILITY 1. Store at 4~30°C in the sealed pouch up to the expiration date printed on the package. Do not freeze. 2. The test device should be used within 1 hour after taking out from the foil envelope. 3. Keep away from sunlight, moisture and heat. 4. Kit contents are stable until the expiration date printed on the outer box.

INTENDED USE The Finecare™ 2019-nCoV lgM/lgG Test is a fluorescence immunoassay used along with Finecare™ FIA Meters for qualitative detection of IgG and IgM antibodies of novel coronaviruses (2019-nCoV) in human whole blood, serum and plasma specimen.
