Negative test 22 days after possible exposure

[Sallymae12]

Hi I was just wondering what the chances are that I have actually contracted hiv even though this test was negative. It was an antibody test. I had vaginal protected sex with a man of unknown status. However, I did perform oral sex on him for a bit. There was no ejaculate, but perhaps a little bit of pre-ejaculate. I have done the research and know that the chances of becoming infected are very slim. It is important , however, to note that I do have braces so small cuts in the mouth are very possible. I just finished a course of antibiotics for a uti. Since then I have developed severe itching all over my body but there is no rash. I also had a fever and night sweats for one night about 14 after possible exposure. Please do not comment telling me to get tested again to know for sure as I plan on doing this anyway. I am just looking dr some advice from well informed people. Thank you

just to verify that the 3 percent mentioned in the cdc guidelines are those with Very seriously compromised immune systems.the instances have to be taken into account when producing data.i dont usually post in the forums because i feel i do not have the knowledge to do so.DAVEIN.stop feeding your anxiety.leave the analysing to those with more education.there is an anxiety based forum you can post in . thanks and goodbye

Although you have no exposure to HIV so you didn't need to get tested.

Oral sex is considered zero risk activity by this website and very very low by some other websites as there is only theoretical risk and no documented cases reported yet.

But as far as testing is concerned test after 3 months is considered 100% conclusive if there is high risk exposure, recommended by CDC and manufacturers of testing kits.

As per CDC or Medhelp.org : MOST people will develop detectable antibodies in 2 to 8 weeks (Average 25 days). Although a negative result after 28 days is a good indicator of HIV status but to be fully confirmed it is always recommended test after 3 months.

As per CDC gov website
=================
Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days).

Even so, there is a chance that some individuals will take longer to develop detectable antibodies.

Therefore, if the initial negative HIV test was conducted within the first 3 months after possible exposure, repeat testing should be considered >3 months after the exposure occurred to account for the possibility of a false-negative result. Ninety seven percent will develop antibodies in the first 3 months following the time of their infection
=================================

As per one article on medhelp.org
=========================

- HIV 1 and 2 antibodies and p24 antigen test (HIV DUO or HIV Combi test)

This HIV test is licensed in the EU for use after 28 days after a possible exposure. It is probably much better than this and will probably identify the majority of newly infected HIV positive individuals at between 14 and 21 days. This HIV test is referred to as a fourth generation HIV test. Certainly in our clinic we have had many new diagnoses of patients using this HIV DUO test combination in that time frame.

So in general, p24 antigen is formed slightly before antibodies are forming allowing us to close the gap between infection to detection time - the HIV window period. As time goes on, then the majority of newly infected HIV positive people will form antibodies to HIV 1 or 2 by 28 days. In combination then, looking for both the HIV 1 p24 antigen and also HIV 1 and 2 antibodies will allow for much earlier detection of HIV than looking for HIV antibodies alone.  
============================

- HIV 1 and 2 antibody test

We have moved from rudimentary tests in the early 1980's to modern, accurate, easy to use third and fourth generation HIV testing methods in 2010. HIV 1 and 2 antibody tests in use in the UK will be either third or fourth generation test. Modern third generation tests will identify well over 99% of newly infected HIV positive people at 6 weeks after exposure even though they are licensed for use after 12 weeks after a possible exposure.

Once again, I am not trying to debate with you as to whether or not I've had an exposure. I have read that the average time for antibody production is between 21 and 25 days. 22 days would obviously fall into this period

[Teak]

They aren't accurate if one has had an exposure which you have not.

[Sallymae12]

I'm not trying to debate that with you. I am asking how accurate an antibody test post 22 day possible exposure is

We can't tell you what to believe, but we can tell you that our forums aren't a venue for debate over our stance that oral sex carries no risk for HIV.  Our stance will not change unless we receive definitive scientific evidence to the contrary.

[Sallymae12]

Unprotected oral sex is a possible exposure. Especially when giving not receiving

[Teak]

You never had an exposure.
