Window period

Exposure through burst condom as insertive vaginal sex male but the woman was on top.


CDC says

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 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.

Another type of test is an RNA test, which detects the HIV virus directly. The time between HIV infection and RNA detection is 9-11 days. These tests, which are more costly and used less often than antibody tests, are used in some parts of the United States.

For information on HIV testing, you can talk to your health care provider or you can find the location of the HIV testing site nearest to you by calling CDC-INFO 24 Hours/Day at1-800-CDC-INFO (232-4636), 1-888-232-6348 (TTY), in English, en Español. Both of these resources are confidential.


Why do many experts say 3months is definate and also quote the CDC guidelines.

Re: Window period

The 3 % that are talking about fall into 3 groups

1, Long term IV drug users
2, Are on Agressive Chemo
3, Taking anti rejection drugs for organ transplants.

Even then its very rare they test postive after 3 months

Did you have risk you would like to ask us?

Re: Window period

My exposure was through burst condom as insentive vaginal sex male but the woman was on top, lots of symptoms and almost sure am infected but hope not.

Do these people really constitute 3%? i doubt.

Again CDC has not specified the make up of 3%.

Re: Window period

Hi,

Here is what Edward D Hook MD ( a leading HIV expert) had to say when asked the very same question.

"The figures you use to justify your concern suggest that you are a victim of internet mis-information. The idea that 3% of HIV infections are undetected at 3 months is preposterous. I know of no expert or report in the medical literature that suggests that anyone who has not take n therapy for HIV in efforts to prevent infection takes more than 8 weeks for their blood test to become positive. "

And here is CDCs own testing guidelines.

http://www.cdc.gov/globalaids/Resources/pmtct-care/docs/TM/Module_6TM.pdf
Page 11
#4

"In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results"


Kevin.

Re: Window period

Apollo,

My doubt is out of fear due to persistent symptoms that may not be facts.

Yes i tested Negative at 3months but still have symptoms.

Kevin,

Thank you for the information but:

"Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results"

and

"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. In very rare cases, it can take up to 6 months to develop antibodies to HIV."

are the two statement from the same organization not conflicting?

Could one of them be misleading? i can't say which one.

Re: Window period

Did you read what Dr Hook said ? He was very clear in which one was misleading. He said "The idea that 3% of HIV infections are undetected at 3 months is preposterous I know of no expert or report in the medical literature that suggests that anyone who has not taken therapy for HIV in efforts to prevent infection takes more than 8 weeks for their blood test to become positive." This is from a world leading expert on HIV who has worked with HIV for the last 30 years.

If you wish to fuel your concern by reading contradictory statements please do so, it will not make a jot of difference to your HIV status. CDC guidelines do not determine when an HIV test is conclusive; the manufactures and the administrators of the tests determine when they are conclusive. There is no approved HIV test that is not conclusive at 3 months.

Is there any reason you did not ask the people who actually did the test whether they considered it conclusive or not, or is there any reason you will not do so now?

Buddy you can spend the next three months worrying needlessly and have another HIV test only to get another negative result or you can move on and put this to bed, your call.

Kevin.

Re: Window period

If you have symptoms and tested negative then you won't have HIV. The 3% that may need to test at 6 months mean they didnt serconvert, your belief is that you have and that proves it's not from HIV.

The information your posting is selective at best so I would recommend you read kevins post as that's about all that needs to be said.

Whilst I can understand your concerns you are HIV negative

Re: Window period

Since the change of guidlines for conclusive resukt at 3months, no case has been reported of late seroconversion for one who isnt among the listed groups?
Please tell me the honest truth not just to ease my mind.

Re: Window period

Nothing is said on any HIV forum “just to ease your mind”, ever. False hope is never offered here. Beyond the exceptions listed there are NO cases of anybody testing positive after a three month negative result, none, zero, zip.

If you are so concerned about all this, please get off the net where you are simply fuelling your own anxieties and go back to the test centre and ask the professional staff there for their opinion.

Buddy doubting a conclusive negative result and fuelling your own anxieties on HIV forums is of no benefit to you. Please speak to the people who did the tests if you still have concerns.

Choosing not to accept a conclusive negative result is to deny reality and this is for you now to deal with. You can accept the reality of a conclusive negative result or you can continue, through choice, to obsess about HIV and deny reality. Either way you cannot be helped further with your deniel, HIV anxiety and obsessions here.

Kevin.
