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. Clinically, the test is to be used as an aid in the diagnosis of coronavirus infection disease (COVID-19), which is caused by 2019-nCoV. The test provides preliminary test results. Negative results cannot exclude the possibility of 2019-nCoV infection and they cannot be used as the sole basis for treatment or other management decision. 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.
