Hi well come to HCM.
All the test done in same day to diagnose HIV
as early as possible and if positive earlier
the treatment better can be the result. But for final confirmation one should go on testing with PCR test which is more reliable. Intially for six month test could be negative
inspite of pt having HIV.This period is called window period. And if PCR is negative after
six month you are sure of HIV. being negative. Take care. Thanks
