• You do not need HIV.
• You examined too quickly after publicity, earlier than detectable HIV antigens or antibodies might develop.

However, a reactive end result implies that the take a look at confirmed a response, suggesting the presence of HIV antigens or antibodies in your pattern. This suggests a positive HIV infection.

HIV antibody take a look at outcomes are correct greater than 99.5% of the time.

Healthcare suppliers might take a look at your pattern two or extra occasions to substantiate the outcomes earlier than you obtain them. The primary take a look at known as an enzyme immunoassay (EIA) or an enzyme-linked immunosorbent assay (ELISA) take a look at.

Inaccurate outcomes might happen in the event you had been examined throughout the window interval.

The window interval is the time between your publicity to the virus and when your physique produces sufficient antibodies for the take a look at to detect. Normally, your immune system takes about three weeks to 2 months to provide detectable antibodies. Testing throughout the window interval usually results in non-reactive (adverse) outcomes, even when you have HIV.

Because of the potential for a false adverse end result throughout the window interval, retesting for HIV could also be obligatory, particularly when you have sure threat components. These might embrace:

• You had vaginal or anal intercourse with somebody who has HIV.
