I wonder why King County Health Department doesn't say that?
"we recommend that people wait 3 months from the time of the possible infection with HIV (the date of latest exposure) before being tested for HIV antibodies. The test may not give an accurate negative result if a person gets tested too soon after a potential exposure."
Oh guess who works there too? Dr. Handsfield
8 weeks usually suffices for a risk...as Dr. Handsfield has said numerous times on HIS forum.
The remaining 4 weeks is primarily for IV drug users and persons who have a compromised immune sysytem.
12 weeks is usually considered conclusive by most international standards.
I'm sure if you would read the replies that have been given here you will find the answer along with were to look in the CDC training manual. Those people answering the phone probably no less than you did when you called them.
Breton I heard samething from me also.
