HIV tests - genetic?

Jul 29, 1999

How do you test for HIV? Can it be determined GENETICALLY? Is the 'Line Immunoassay' method as successful as the Western Blot and ELISA methods, and how does it work?

Response from Dr. Holodniy

You can look for antibodies to HIV or you can look for HIV itself through PCR testing among others. Line assays or recombinant immunoblot assays are equivalent to western blot testing. The assays have pieces of HIV stuck to paper strips which bind HIV antibodies in the blood if they are present. A color reaction tells you if they are there. MH
