Hiv test

Hey! I had an unprotected sex 4 years ago and now i have gone through hiv test which provides the result as non reactive..it was a rapid test ..2 days ago i had another hiv test which also showed non reactive ..do i need any further tests? Or should i assume that i dont have hiv... I took test from different labs..do i have chance of transmitting hiv through their syringes which they have used for taking my blood samples..i am worried ..pls help me

No you do not need to test again. There is no way you could get hiv form having your blood taken as each needle is disposed of after use and a new clean needle used for each person. It sounds like you are a very anxious person and I expect this is not the only thing you worry about . I would advise you see your GP about your anxiety .
