12 vs. 24 weeks

I am a bit confused.

On this site "you all" state that 12 weeks is the magical number for a clean bill of health regarding a positive HIV test. I was at my local clinic on Wednesday and after my 8 week test (which was negative), they stated that I should come back at 12 weeks and then if that test is negative I should return at 6 months (24 weeks) for a final verification.

What is the "real" answer?

Is the conclusive at 3 months (12 weeks) or is it 6 months (24 weeks)?

According to the HIV doctors at this particular clinic they adhere to the University of San Francisco's studies. In addition they state that the CDC's studies/recommendations is that 6 months is the conclusive test.

Who is right?

they are soooooooooooooooooooooooooooooooooooooooooo wrong.  your clinic needs to update it's infomation.  the cdc does NOT say 6 months is conclusive...that is the OLD guideline.

3 months IS conclusive.

There months is the guidelines setup by the mfg., FDA and the CDC. I don't believe you found a clinic in SF that uses 6 months. The SF City Clinic one of the largest follows the 3 month guidelines.

Dear Teak,
Thanks for your great job to help all of us!
Regarding this issue I also have the same confusion with bigdogdog. I found something as below:

"...HIV-antibody testing by enzyme immunoassay should be used to monitor HCP for seroconversion for >6 months after occupational HIV exposure. After baseline testing at the time of exposure, follow-up testing could be performed at 6 weeks, 12 weeks, and 6 months after exposure. Extended HIV follow-up (e.g., for 12 months) is recommended for HCP who become infected with HCV after exposure to a source coinfected with HIV and HCV..."

Here is the link for your reference and which is updated on 30 Spet. 2005: http://www.aidsinfo.nih.gov/Guidelines/GuidelineDetail.aspx?MenuItem=Guidelines&Search=Off&GuidelineID=10&ClassID=3

So, can you give some comments? Thank you very much!

You were citing "occupational exposures" their testing guidelines are set by OSHA and their insurance companies  and has nothing to do with nonoccupational exposures guidelines.
Avatar universal
Occupational Exposures Often involve a 28-day course of PEP (Post-Exposure Prophylaxis). The window period doesn't begin until the end of this course.
Avatar universal
Not all person with occupational exposure are given PEP.

Why then the baseline for Occupational exposures is up to 12 months?

Do not pull up and post to old threads.

I wish everyone could get the memo and advise that 3months is the window period. the san francisco aids foundation still says it takes 2-3months for most people, BUT it can take up to 6 months. with such a huge pop. of hiv patients, you would think they would stick to 3 months.

* Anyone who continues to post excessively, questioning a conclusively negative result or no-risk situation, will be subject to action by MedHelp. Conclusively negative results or a no-risk situation will be based upon the criteria established by MedHelp’s doctors. Action will be taken as follows:
    * After excessive posting, a warning will be issued by MedHelp
    * Continuing to post regarding the negative result / no risk situation will result in a 3 day suspension
    * Continuing to post upon your return will result in a permanent ban.

and to justify the nurses explanation, he said that that is what the manufacturer says, up to 6 months......but on the Orasure website it says up to 3months..weird....just sharing...
Good day
