Respected sir Is tri dot test validate & reliable after sufficient window period of 12 month after exposure is it possible that this test can came positive without exposure after 24 month or later. Condom use karke sex karne se kya hiv ni hota hai but jab hum after sex condom remove karne hai tab vaginal fluid jo ki condom ke outside laga hota hai remove karne time hand par lag jata hai later hand wash with cystic soap karne par koi risk to nahee rahta hai.
