False negative now positive?
Mar 22, 2006
I was exposed 3 years ago and notified by a doctor recently. I went to take an Oraquick Advanced (fingerstick) at a clinic and it was negative. I saw my doctor and he wanted other testing. This time the quick test was indetermined (sp). I've been sent to the clinic to request a blood test. Do the quick tests give false negatives? I've heard of false positives but not negatives.
Response from Dr. Frascino
I agree with you. If your last exposure was three years ago and you had a recent negative finger stick OraQuick, you are definitively HIV negative and no further testing is warranted or necessary. I'm not sure why your doctor suggested another "quick test." However, based on your previous negative test, the follow-up "indeterminant" result is the "false" reading. Although unnecessary in my opinion, I'm quite confident your next "blood test," which will probably be an ELISA, will be negative, confirming what we already knew from your first test.
