What is a HIV WESTERN BLOT?

The HIV Western Blot test is a specialized confirmatory blood test used to detect antibodies against HIV. It is performed after an initial screening test, such as ELISA, shows a positive result. By identifying specific HIV proteins, the Western Blot provides highly accurate confirmation of infection. Healthcare professionals recommend this test to rule out false positives, establish a definitive diagnosis, and guide appropriate medical care and counseling for individuals at risk or suspected of having HIV.
