HIV tests are used to detect the presence of the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS), in serum, saliva, or urine. Such tests may detect antibodies, antigens, or RNA.
When you test for HIV, you may decide you don't want to see your regular doctor. Or, you may prefer to have a trained testing counselor on hand for you. In this case, you could look in the phone book to find the number of your local Department of Public Health. standard antibody test does not look directly for HIV. Rather, it checks for antibodies -- proteins your body makes in response to having HIV. If you have these antibodies, you are considered to be HIV-positive. That means you have HIV, the virus that causes AIDS.
