What Could Be The Confirmatory Test For STD?
Dear doctor,
11 week ago I had a sex with prostitute from Ukraine. During the sex condom broke. I do not know how long it lasted but I figured and out change the condom before any ejaculation and continued to the sex till ejaculation with the new condom about 10 mins more.
After 4 week of this intercourse I got tested negative with 3rd generation using Siemens Centaur assay.
Yesterday I got retested again using same assay and I will get the result in 6 hours.
My questions are;
How reliable for week test? I read that 3rd gen. sandwich assays has window period 21-25 days
If (I hope) 11 week test is negative should I be retested?
Thank you very much

Hi,
Welcome to HCM.
Broken condom has some risk for HIV. Negative test 11 weeks after the high risk contact almost rule out the possibility. Anyhow another test after 12 weeks would be more conclusive. 3rd generation test can rule out HIV 1 by four weeks after High risk activity whereas the same combo test can rule out both HIV 1 and HIV 2 by 12 weeks. But HIV 1 is common throughout the world (almost 99%) compared to HIV 2.
