A person got HIV non reactive after six months encounter is there any possible of getting positive?

It is highly unlikely for a person to get a positive HIV test result after a non-reactive test result six months after a potential encounter.

The standard recommended testing window for HIV is 4th generation testing, which can detect the virus within 28 days of infection in over 95% of cases. If the test result is negative at the 6-month mark, it generally indicates that the person did not contract the virus during the potential exposure.

However, it is important to note that early testing may not always detect a recent infection, especially during the window period. The window period refers to the time between when a person is infected with HIV and when antibodies against the virus become detectable in the bloodstream. This period can vary from a few weeks to several months.

If you have any concerns or doubts, it is always best to consult with a healthcare professional for further guidance and testing if necessary.
