ANTIGEN TESTANTIBODY TESTSURFACE ANTIBODY TEST
SCIENTIFIC DESCRIPTIONReverse Transcription Quantitative Polymerase Chain Reaction (RTqPCR) detection of SARS-CoV-2 virusSerological immunoassays that detect viral-specific antibodies (for example IgM, IgA, and IgG)Screen for envelope gene followed by confirmatory RT-PCR test for SARS-CoV-2 virus
POTENTIAL UTILISATIONTests if a donor has the virus and has potential to be contagiousTests if a donor has had the virus and has the potential to be immuneEnvironmental test for SARS-CoV-2 to determine efficacy of cleaning regimes and general hygiene levels in office, communal and production areas
OPERATIONSwab from the deep nasal areaBlood sample (minimum of 2mL)Environmental surfaces sampled with pre-moistened swab
SPEED OF TESTING24 hours*24-48 hours*4 days* (3 days to screen for corona- virus, 1 day to confirm presence of SARS-CoV-2 virus).
APPROVED TESTSTests are run at a laboratory holding ISO accreditationTests are run at a laboratory holding ISO accreditationTests are run at a laboratory holding ISO accreditation. Swab kits are UN 3373 compliant
