testing question

On 15-august I had an unprotected sex with a female co-worker (major mistakes on many levels I know).  
I tested negative at day 2 and 5.  She tested negative at day 3.  
All tests were the standard elisa antibody (not duo or p24 antigen etc).  
This is the only intercourse I have had since early June (when I was still in my long term -2yr- relationship which hit few bumps.)  Now we are in the process of reconciling I hope.  
I don't know my co-workers sexual habits.  When is the earliest she and I can both retest to know for sure I did not get HIV from her?  
I am looking for confidence for when I can safely re-start sexual activity with my girlfriend.
Thanks for your help.

At this point there is no reason for you to worry further. EWH

Welcome to the Forum.  The chances that your partner gave you HIV are very, very low if she had a negative test 3 days after your encounter.  Persons who have HIV and are able to transmit it to others typically have positive tests or their tests become positive within a week or two following the encounter.  The quickest and most direct way to address your question, if she'll do it, is for your co-worker to get tested again at about 2 weeks following the encounter. If she is negative at that time, then there is no risk.  

As for your own testing, standard antibody tests are 100% conclusive in situations such as yours at 8 weeks following an exposure.  

As I said, the likelihood that you acquired HIV through this single encounter are truly miniscule.  I would not be worried if I were you.  I hope my comments provide some direction. EWH

My co-worked re-tested negative at day 16.

Dr, so it's a scientific impossibility for her to have passed HIV to me given this test result?

Thanks for the help.
