The AIDS test is a test that measures the immune response to HIV, consisting of antibodies that are generated in response to the infection.
Standard AIDS Test
The Standard AIDS Test measures antibodies. These take time to develop, so in the very early stages of infection there may be a negative antibody test even though the person can be infected
Under these circumstances HIV infection can be checked by measuring the virus in the blood using either:
-
a p24 antigen test (available through health care professionals)
-
a viral load assay
Tests should be carried out on:
-
anyone who had a blood transfusion before 1985
-
anyone who has had unprotected sex with an infected person
-
infants of infected mothers
