Hello, if you read my previous message about a week ago, this is just a follow-up to that. I had sex with a 52-year-old woman Tuesday December 17th and it was unprotected, vaginal, oral and kissing just once she was with a previous guy Saturday December 7th she said he wore a condom. She was with him a handful of times. But anyway, the following day last Wednesday December 18th she went to get tested for HIV and STDs Aunt. The HIV test was negative and that was about 10 days after she was with that guy on December 7th. So is there any way that I can still get HIV from her if she tested negative 10 days after him and then I was with her last Tuesday December 17th. Is there any way I could still be positive or know if she tested negative?. Do you think I could still get HIV if she had it if she tested negative the day after we got unprotected? Also, she said she tested positive for syphilis and she's going to start penicillin so I was with her 10 days ago. Should I be tested for syphilis now? Also, I am going to get a HIV RNA test.. is it okay to take the RNA HIV test tomorrow or Saturday? I was with her Tuesday, December 17th

I'm sorry you found it necessary to return.---

Ok will do... I'll update your accordingly..... Can I take the HIV RNA test Saturday Dec 28 in the morning ??? I had sex with her Tuesday night Dec 17.. 

There are no data by which to know if there's a difference in reliability at 10.5 versus a full 11 days. Why not avoid the uncertainty and wait another day (until 12/29) before testing?---

Hello, update here... So, as for myself I went to my doctor yesterday 12/27.. told him the entire story.. he wanted me to have all HIV / STD testing regardless.. so it was 10 days after my unprotected encounter these tests were taken.. the syphilis test came back negative; though the woman I was with tested positive for it Dec 18th..  I have no symptoms etc... thoughts? I read for a person to acquire syphilis from one unprotected  encounter with someone who has it already is a 10-30 percent chance.. you agree? Also, the last time the person I had unprotected sex with on December 17th.. she said her last time before me was December 7th...then me Dec 17th .. she took a HIV RNA test yesterday morning (20 days ) after Dec 7th.. this is conclusive for her right? I am going Monday for my HIV RNA test in bought as well... It'll be 12.5 days since December 17th - Dec 30th.. that ok? Should be negative? 

The 20-30% risk of syphilis for sex with a newly infected person is probably about right. So the odds are in your favor there. Still, if your partner's positive syphilis test result has been confirmed (i.e. positive on a confirmatory as well as the initial screening test), you should be treated with long acting penicillin. I'm surprised (and disappointed with your doctor) that this hasn't been done yet. Failure to treat you flies in the face of all standard recommendations by all authoritative, knowledgeable experts and agencies for several decades. (As suggested above, you could call your local or state health department to confirm this. Or just show this discussion to your doctor.) Of course this makes assumptions about the certainty of your partner's diagnosis. In any case, your negative syphilis test at 10 days is only valid as a baseline to know you didn't have it before. If not treated, you should be tested at least at 2 week intervals; and you'll need to hold of on any sex with anyone for the next several weeks until you've had another negative test result in 6 weeks.---
