I am 24 years old male. My possible encounter was on 9th september, since then I am worrying about hiv. Finally after 5 months + 1 week I tested for hiv on 15th february by Dr. trust hiv sure blood test kit it came negative. Then after yesterday on 18th february I tested for hiv in laboratory it was tri dot hiv test it also came back negative. Questions:- 1) now I need to worry about hiv? 2) should I go for hiv test after 6 months? 3) can I consider this test result as an conclusive result?
