उत्तर
Western Blot is a highly specific confirmatory test used after a positive ELISA result. It detects antibodies against the viral core protein and envelope glycoproteins of HIV, providing definitive confirmation of HIV infection. Its high specificity makes it an excellent confirmatory test to rule out false positives from initial screening.
