Overview By Mayo Clinic Staff Print Human immunodeficiency virus (HIV) testing determines whether you're infected with HIV, a virus that weakens your immune system and can lead to acquired immunodeficiency syndrome (AIDS). Some HIV tests check for antibodies that your immune system produces in reaction to HIV infection. Other HIV tests look for evidence of the virus itself. Rapid tests can produce results within 20 minutes. Request an Appointment at Mayo Clinic Why it's done Jan. 21, 2017 Print Share on: FacebookTwitter References HIV test types.
