It is very important to have basic HIV information for timely diagnosing and managing this disease and to prevent it from spreading.

Diagnosis of HIV infection has been rendered easier by advancements in medicine and technology. Various tests are available to detect the HIV virus.
HIV/AIDS testing is carried out on Blood and Saliva. Anti HIV antibodies detection is the most commonly performed test to diagnose HIV. This is a routine test performed for diagnosis and is not very expensive. Sometimes in this test, HIV/AIDS is not diagnosed because antibodies are not formed at the time of testing. The body takes a few weeks to months for developing anti-HIV antibodies.

ELISA is another test that helps diagnose the HIV status. It is a sensitive test done for screening. If a person is found HIV positive, Western Blot test is advised for confirming the diagnosis of HIV infection. If again found HIV positive, the person is given HIV treatment.

Some tests like CD4 counts and Viral Load are carried out to diagnose the progress of the disease.CD4 cells, which are a type of cells destroyed by HIV infection, give an idea about the status of infection, while viral load is an indicator of the amount of HIV virus in the blood.}
