A Counselor at the Massachusetts Health Department just told me that the ELISA is 100% accurate at 6 weeks. I know nothing is ever 100% but as anyone heard about this? I thought the standard was 12 weeks for the ELISA.
Thanks!
Stella,
An ELISA test at 6 weeks is an EXCELLENT indication that you were not infected.
As you know, ninety seven percent (97%) of people will develop HIV antibodies in the first three months after contracting the virus. In very rare cases, it can take up to 6 months. The CDC still recommends a 6 MONTH test just to make absolutely certain one is negative.
This is probably because we're dealing with science and on very rare occasions, there have been individuals who have seroconverted after 6 weeks. When recommending testing, doctors want to make sure they catch the rare cases, too.
