Diagnosis HIV is most commonly diagnosed by testing your blood or suliva for antibodies to the virus. Unfortunately it takes time for your body to develop these antibodies-usually up to 12 week. A newer type of test that checks for HIV antigen, a protein produced by the virus immediately after
 infection, can quickly confirm a diagnosis soon after infection [5). Following are the tests for detection of HIV AIDS: 
Home Test:
 A Food and Drug Administration-approved home test. To do the test, you swab fluid from your upper and lower gums. If the test is positive, you need to see your doctor to confirm the diagnosis. If the test is negative, it needs to be repeated in three months to confirm the results. 
Tests To Tailor Treatment :
If you receive a diagnosis of HIV/AIDS, several types of tests can be done. These tests include: 
•: CD4 count 
CD4 cells are a type of white blood cell that's specifically targeted and destroyed by HIV. 
• Viral load :
This test measures the amount of virus in your blood. Studies have shown that people with higher viral loads generally fare more poorly than do those with a lower viral load.
