Is cmia 4th hiv combo agab test negative at day 30th after pep (total 58 days since exposure) conclusive? if not, what is the chance it will turn positive?

Almost zero, but for truly conclusive results, have another test at least 45 days after last PRP dose.

Agree with Dr. Handsfield. However, HIV is only one of the STDs. A condom may not protect against HPV, Herpes, LGV, syphilis, pubic lice etc. It would be prudent to see your doctor for an evaluation. Visit this site for information: https://www.cdc.gov/std/default.htm Wish you good health!
