Diagnosis of AIDS and HIV Infection

Screening for HIV infection is most commonly done by testing blood for HIV antibodies. A newer test, the Orasure test, involves collecting secretions between the cheek and gum and evaluating them for HIV antibodies.

Orasure is essentially as accurate as a blood test, and, because it doesn't involve a needle stick, it is favored by many individuals. Orasure is available through physicians’ offices and many public health clinics.

Finally, a new urine test available for screening, although if the test is positive, blood tests need to be performed for confirmation of the presence of HIV.
