    Question about testing accuracy and my situation

    cpd123 posted:
    Hello,


    I had sex in which I was the recipient of anal sex. I also had oral. Oral was protected until the last minute, then he finished giving me oral. The anal was protected at first, but I am not sure if it was the whole time.


    I went and was tested at 2 weeks post exposure.It was a rapid test and was negative. I was tested again at 4 wks (26 days) post exposure with an Antibody (3rd gen) and an RNA. Both were negative.


    I am still very concerned about this. Should I feel somewhat comfortable or reliable with those results and the tests? I am going to get tested again at 5 and/ or 6 weeks. Would those be ones that I should feel good and reliable with?


    I realize 3 months would be ideal, but I cannot wait that long. I have read that antibdy tests at 28 days are fairly reliable and that the RNA test at about 2-3 weeks is also. Any advice or info would be greatly appreciated.

    Oral sex carries an extremely low risk of HIV transmission. Think along the lines of .5 to 1 per 10,000 exposures with a source known to carry the virus.


    Protected anal intercourse is, indeed protected assuming a condom was used and used accurately. The virus cannot cross an intact latex condom.


    If you remain concerned the recommended time for testing continues to be 3 months.

    I do still feel concerned.

    I am going to test at 3 months, but with the ones I have taken being negative and their windows, should I be very worried?

    I cannot say for sure the condom was used the whole time...

    A test done at 4 weeks after a potential exposure is considered to be 95 percent accurate.


    By 3 months this has increased to 99.99 percent.


    The odds remain very much in your favor toward a negative status.
