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.
An HIV test is the only way to tell for sure whether you have HIV. A few weeks after infection, many people have flu-like symptoms, which then disappear after a while. These symptoms can include fever, headache, tiredness, and enlarged lymph glands in the neck and groin area.
