Western Blot Negative!
May 5, 2010
I recently got tested for HIV and the Western Blot came back negative 'on all bands'. My only exposure was 17 years ago, but I had some weird symptoms. My question, "Is the Western Blot accurate after this link of time?" The worst it would be is 'indeterminate', it wouldn't show a 'negative' on all bands if it wasn't negative, would it?
Response from Dr. Frascino
The recommended test for HIV screening is an HIV-antibody test (ELISA, EIA, rapid test, etc.). The Western Blot is a confirmatory test that should only be run to confirm a reactive (positive) screening test!
That said, your negative result is definitive and yes, HIV-screening tests and Western Blots would be accurate 17 years after an exposure. You can read much more about HIV diagnostic tests in the archives of this forum. Check it out!
