Certain exposure! Tested 8 weeks negative

Dr.
I had unprotected vaginal sex 2 times with a guy who subsequently found out he was HIV Pos and has been for 3 years. He ejaculated in me both times. I had a blood donor test at 6 weeks and a test at my health dept at 8 weeks after exposure...both negative. They want me to come back in 3 months for another. I am scared to death! What is the liklihood that the 8 wk test was wrong and I really am positive?

Your 3 month test will be conclusive.

I wonder also what is the possibility of the 8 week test was wrong. I had a similar experience and going through the fear of my risk also from 3 weeks ago. I hope you test negative and God bless!

Hi usgirl26,

Sorry to hear about your frightening episode.

The thing that might help to ease your anxiety, is that the majority (but not all) of people who are truly infected generally test positive within 4-6 weeks. Your negative result at 8 weeks is therefore, pretty encouraging.
You will still need a conclusive, though, as Teak said, at 3 months to know for sure.

At the same time, may i ask what is your blood donor test about?


May God bless

good news guys although 12 weeks is conclusive for the US and noumerous other countries,,, In Greece, which is where i am from the guidelines at the public health  which as i am told by the doctor are given by the Europian Union state that 8 weeks is conclusive and no one can come in argument wheter are conclusive or not if u re 8 weeks.

It is recommended you test at 3 months post exposure for your conclusive result REGARDLESS of what you have been told. You can choose to test when you want, but if you want a for sure 100% conclusive result test at 3 months end of story.

WHO window period is 14-21days.

http://www.who.int/diagnostics_laboratory/faq/window_period/en/

Window period
What is the "window-period" and how long is it?
This is the time between original infection with HIV and the appearance of Detectable antibodies to the virus, normally a period of about 14-21 days.

o All approved rapid HIV tests are very reliable. Any HIV test, however, may fail to detect infection in individuals
who were exposed to HIV 3 months after the exposure occurred to account for the possibility of a false-negative result. Ninety-seven percent of persons will develop antibodies in the first 3 months following the time of their infection. In very rare cases, it can take up to 6 months to develop antibodies to HIV.

How long after a possible exposure should I wait to get tested for HIV?
Most HIV tests are antibody tests that measure the antibodies your body makes against HIV. It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. This time period is commonly referred to as the “window period.” 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 of persons will develop antibodies in the first 3 months following the time of their infection. In very rare cases, it can take up to 6 months to develop antibodies to HIV.

There is no debate (among experts) about the HIV risks associated with oral sex. The risk is so low that almost nobody who cares for HIV infected patients has ever had a patient believed to have been infected that way. Among experts, it's a semantic issue about using terms like "no risk" and "very low risk". There is no difference between my or Dr. Hook's use of "low risk" and other experts' "no risk".
DR. HANSFIELD

"And oral sex is basically safe sex -- completely safe with respect to HIV and although not zero risk for other STDs, the chance of infection is far lower than for unprotected vaginal or anal sex. Please educate yourself about the real risks. If you stick with oral sex and condom-protected vaginal or anal sex, you have no HIV worries and very little worry about other STDs. " DR HANSFIELD

"I am sure you can find lots of people who belive that HIV is transmitted by oral sex, but you will not find scientific data to support this unrealistic concern..." DR HOOK
"HIV is not spread by touching, masturbation, oral sex or condom protected sex."- DR. HOOK
in the public HIV Prevention forum of MedHelp, TEAK and the other moderators maintain that oral sex in all forms is a zero risk activity. Would you agree with this assessment?
I TOTALLY AGREE / DR GARCIA

"The observation on thousand and thousand of observations is that HIV is not spread by oral sex (of any sort)." DR HOOK

On MedHelp, we follow the guidelines set by the Centers for Disease Control (CDC), test manufacturers, FDA, and our experts, Drs. HHH and Hook.

For this forum, it is 3 months. Yes, a 6 or 8 week test may be accurate, but it's not conclusive until 3 months. Saying that the 6 or 8 week test is a good indicator is fine, but to be conclusive, testing must happen at 3 months. It is also this forum's position that oral sex by itself does not require testing.

You can quote doctors, but make sure you say that. Doctors are licensed to practice medicine and can say that given the particulars about exposure, timing, etc., that someone doesn't need more testing. However, unless you are a doctor, you can't say that.
