What are my chances

[saha99]

I had multiple unprotected sex with a female of unknown status and I did HIV antibody test after 33 days post exposure which came back negative...... I know it's not conclusive but is it likely to change?   The test that was used is alere determine HIV 1&2 that's check for only antibody

It is still possible, though not highly likely, that your antibody test will change.  Since the test is intended to be conclusive at 90 days from your last exposure, I can't give you odds for a test taken at any point in between, but the closer to 90 days, the more reassuring your result will be.

Is your partner able to test? A negative test from your partner would be reassuring.
