Welcome to HCM.
If the HIV
tests are negative after 3 months of risky exposure, then there is no chance of getting HIV unless there is a fresh exposure.
So you are free from HIV and need not worry.
The cut off value is up to that the reading of the test, it indicates a negative test,. The reading above the level of the cut of value, especially in your test, if the value is above 0.4 then it is positive. In your case it is less than 0.4, that is just 0.19, so it is negative.
So forget about your past.
is always better and we avoid unnecessary tension.
