Still you have to test if were 11 months HIV negative?

If you have tested negative for HIV 11 months after a potential exposure, it is highly unlikely that you have HIV. The vast majority of people who are infected with HIV will develop antibodies to the virus within 3-12 weeks of infection. This means that a negative test result 11 months after a potential exposure is very reliable.

For most people, 3 tests done at least 90 days (3 months) apart, or 1 test at 1 year after the possible HIV exposure and all are negative results are considered definitive.

However, if you are still concerned about your HIV status, you can talk to your doctor about additional testing or counseling.
