<br>Can it happen?
Is it possible for someone who has TB to test positive for HIV test, then later test Negative?
Hi Ngwana!
Having TB should not affect the result of a HIV test.
That said, the Rapid tests used are very sensitive and can deliver false positives. This is why a confirmatory test (different brand of rapid test) should always be done straight after a positive result on the screening (1st) test.
If in doubt, consider a PCR test (testing for the presence of the virus itself).
Stay well
