Accuarcy of HIV type 1 antibody test with Weatern Blot

Apr 18, 2012

In percentage wise, how accurate is a HIV type one antibody test with Western Blot at 30 days. I called my local hospital and this was all the information I could get on the test. Will it tell me anything close to conclusive at the 30 day mark from possible exposure?

Response from Ms. Southall

Hi With HIV testing there is a 3 month window period, in which you can be HIV positive but yet your Antibody test will come back negative. The first time to be tested is at 3 weeks and then 3 months. At 3 months the Western Blot will be accurate in giving you positive or negative results for 97% of the population, at 6 months it is 100%.

Be well and stay safe Shannon

RIsk of transmission?
