The HIV testing is country specific and the TEST specific...e.g.
In UK the window period is 12 weeks,
in US the window period is 13 weeks while
in India it is said to be 6 months...Also the nature of test conducted like HIV Duo will give result in 28 days et al creates confusion among the people...it means if somebody in UK is negative in UK and if he moves in India the risk is still there....can u guys pls clarify ?
