What is the real window period?

[Coldashell]

CDC says 97 percent at 3 months and 100 percent at 6 months as I called them today, why do they say this?

[Coldashell]

Thanks to both of you for your help and thank you teak for that helpful resource from the cdc and thank you nurse girl for your info as we'll. I am conclusively negative!!!

You have to understand that all the phone reps do at the CDC is read off of a script.  They just parrot the exact same info as is found on their website, and they're not required to have any kind of knowledge base regarding HIV.  

3 months is conclusive, and actually, the vast majority of newly infected people will test + a good bit before 3 months.  With the sensitivity of the modern tests, it usually only takes a few weeks for a test to become +.  If your 3 month test is negative, you absolutely positively do NOT have HIV.

It doesn't and hasn't since 2004.

  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

[Coldashell]

Yes I feel really good about this result but why does the cdc representative say to test at 6 months again? Who does the 6 month window period apply to

[Teak]

Your 3 month test would be conclusive if you had an exposure. You do not need an further testing.

[Coldashell]

Why did the person for the cdc tell me to test again at 6 months? They said only 97 persent of people at 3 months.

[Coldashell]

I recieved a negative oraquick oral test at 12 weeks or 3 months but I don't know if I should test again as the representative from the cdc said to test at 6 months.

[Teak]

The window period is 4 weeks to 3 months.
