Question
I had a unprotected exposure on 16th feb this year with a girl of my neighborhood whose having one more sexually active partner, after 2 months i got tested with hiv elisa test n the result came back negative but i was still anxious and got tested again for elisa after 3 months n 20 days from my last exposure it came back as negative too !!

Are these two tests enough ?? Or i have to retest again ??

My both test results were -

* ABBOTT AXSYM MEIA

HIV - 1&2 ANTIBODIES NON REACTIVE

* INTERPRETATION

HIV - 1&2 ANTIBODIES NON REACTIVE

Answer
kulbir,

it means you were not exposed to hiv from the feb 16th incident; however, there are a few cases, 1 in a 100,000 cases, where the virus may not be detected until 6 months after exposure. the best test to ease your worries is the hiv nucleic acid amplication test. it detects hiv immediately after 2 weeks from date of exposure with a 99% accuracy.
