Hi doctor,
i am an indian,I used condom while having sex with call girl in Singapore about nine month back, due to anxiety,I have been tested thrice for HIV-antibody through ELFA test in 3rd, 6th and 9 month respectively but the result came non reactive, however it is suggested by CDC that test after six month is conclusive but somewher I found in website that it can go up to one to two years, yet I have not developed any symptoms of HIV, should I be tested again after the year??? can window period be more than nine month to produce antibodies,
Regards
