Today, the Mount Sinai Laboratory (MSL), Center for Clinical Laboratories received emergency use authorization from the U.S. Food and Drug Administration (FDA) for an antibody test that was developed, validated, and launched at Mount Sinai by a team of internationally renowned researchers and clinicians of the Icahn School of Medicine at Mount Sinai. This test detects the presence or absence of antibodies to SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) and importantly, may also be used to identify positive specimens with an antibody titer (level) up to a dilution of 1:2880 for the identification of individuals with higher antibody titers.
