i am very worried

I take a fourth generation test combo at the 25 day with 0.21 no reactive, and at the 28 day another with a result of 0.18 no reactive result, and at the 33 day a third generation test with a no reactive result. At this point, Statistically speaking, how reliable are these results ?. 95%? is ther a chance of a late seroconversion?. By the way,  every syntom I read, I have it at the next day, but I think that is in my head. I am really worried, please healp me. My experience was have protected sex with a prostitute. I know that is not a real risk, but I really worried for my syntoms.

A 4th generation test is considered conclusive at 28 days.   Besides that you had protected sex.  You can stop worrying.

Dear friend,
Most people will show antibodies at 22 days. Your 4 th generation test will look for antigen and antibody, it is very reliable to detect early infection. Most doctors will consider your tests as conclusive. CDC guidelines will state that testing at 90 days is the only one conclusive. I an sure your tests will not change. Late sericonversion is only applicable for people under treatment for cancer, ie chemotherapy, and people taking immunosupression medicines after a transplat surgery.

Symptoms are never a way to diagnose HIV, only testing will diagnose.

Having protected sex will not make you contract HIV, do not consider your exposure as low risk, it is a non risk exposure.

So protected sex and with 30 days negative test, you are conclusivly negative
