hi i had a question of my friend. he had sex once (unprotected)with her girl friend.
she told that she don't have hiv. he got tested (tridot rapid test)12th week after encounter, result came nagaitive. and again tested 13th week (same test) its also came negative. after 13th week he tested ELISA came negative. but he worrying about result. it is confusing. the reference range is 0to0.9 to be negative. his result came 0.80. he is worrying 0.80 means half of the disease? should he test again after 3month?
all tests he done after 3 months.
what is window period extremely?

The test at 13 weeks was enough according to the doctors here. Search the website and you will find many who agree.

Well from your post it seems that he was withing the negative range. I think the answer is quite obvious. Also, many of the doctors here say that most people seroconvert around 6-8 weeks.

it is already 14weeks over. hes all tests done after 12weeks.

yup. correct. i searched many websites. and i called local helpline also. they told me window period is three months. according to my knowledge no need to test again. but i've small doubt. 0-0.9 reference range is negative in ELISA test. his result is 0.80. i know its negative. my doubt is healthy person(means a person don't have hiv) reference range should be how much?

Reference range means nothing to you, You have a conclusive NEG test result. You are HIV free

is there any cases found positive, after 3 months negative? mostly the decade 2000-2010.
