The gum test for AIDS is not the most accurate and can be used as a screening test, and a blood antibody test is needed for a definitive AIDS diagnosis. Gum test for AIDS is mainly used to diagnose AIDS by detecting human immunodeficiency virus (HIV) in saliva, but since HIV is mainly found in blood, vaginal secretions, semen, breast milk, amniotic fluid and other bodily fluids, the results of the gum test do not confirm the diagnosis of AIDS. When the gum test is positive, further HIV antibody testing is needed. A positive blood test can confirm the diagnosis of HIV; a negative gum test cannot completely rule out the possibility of HIV. After a diagnosis of AIDS is made, the patient should receive treatment, which should be carried out strictly under the supervision of a doctor.
