serological tests

How Do Serological Tests Work?

Serological tests typically involve the collection of a blood sample, which is then analyzed for the presence of antibodies (proteins produced by the immune system in response to an infection) or antigens (substances that trigger an immune response). There are various types of serological tests, including:
Enzyme-Linked Immunosorbent Assay (ELISA): This test uses an enzyme to detect the presence of antibodies or antigens in the blood.
Western Blot: A confirmatory test that detects specific proteins related to the pathogen.
Rapid Diagnostic Tests (RDTs): These are simple, quick tests that can be performed at the point of care.
Immunofluorescence Assays (IFA): These tests use fluorescent dyes to detect antibodies or antigens.
