The Immunofluorescence Assay (IFA) is a standard technique used in virology. The test is used to confirm the presence or absence of infection antibodies in response to specific viral antigens. The technique is commonly used following an Enzyme Linked Immunosorbent Assay (ELISA) or a Multiplexed Fluorometric Immunoassay (MFIA) as a confirmation of positive results.
