Q

HIV: ELISA, Western Blot Test

A

HIV: blood borne infection in which virus damages or kills cells of immune system, causing progressive failure, leaving vulnerable to other infections
ELISA: “Enzyme-linked immunosorbent assay” blood test used to screen for the presence of HIV antibodies
Western Blot Test: blood test that produces more accurate results than the ELISA, performed to confirm the diagnosis when the ELISA test is positive
