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.
Antibodies are formed by the body in response to an infection; tests that detect antibodies are the standard tests that are performed to check for HIV when there is no concern for a recent transmission. In some states, the patient must sign a consent form in order for a HIV test to be performed. If you are in such a state and did not sign a consent form, then this test should not have been ordered. If you are in a non-consent state, then your physician should tell you one way or another the result of your HIV test.
