Posted on Tue, 16 Aug 2016

Question: Hi Doctor,
I got negative hiv test at 90 days after exposure, i was wondering was it considered 100% conclusive? I did test in Australia and it said HIV 1/2 ab/ag .( Is it 4 generation test) . I did 4, 6, 9, 12 weeks and 90 days all was negative.

Could you pls help me as im quite anxious.

Many thanks Doctor

Detailed Answer:
Hi

Thank you for asking HCM

I have gone through your query. The fourth generation ag/ab test has more than 99 percent accuracy from 28 days post exposure. As you have done it till 90 days there is nothing to worry. You are free from HIV.
There are no case reported positive in further testing after a negative result in 4th generation test 28 days post exposure even. So you can now forget about it and go on with life.

Let me know if anything not clear.
I am happy to help you.
Thanks.
