If you have a negative HIV test at 9 weeks is that conclusive?

Generally, a negative HIV test at 9 weeks (63 days) after potential exposure is considered conclusive in most cases. The window period for HIV, which refers to the time from infection to when antibodies against HIV can be detected in a blood test, typically lasts up to 45 days, but in rare cases, it can extend up to 90 days.

Therefore, a negative HIV test at 9 weeks after the potential exposure provides a high level of certainty that you do not have HIV. However, if you have any concerns or are experiencing symptoms consistent with HIV infection, it is recommended to consult with a healthcare professional for further guidance and possible additional testing.
