Could be it be false positive...yes?

Oct 26, 2007

Dear Bob,

Please refer to my last post below. I went for another test to the next day to get a second opinion if the finger-prick test i took yesterday was a false positive.

The test i have done today was an ORAL-SURE test. The result came out to be negative. Can i now say that i am conclusive negative? So does that means that the last test i took the previous day was truly a false-positive? Can I sleep in peace now that the latest test shows that I'm negative? or should I wait for the western blot test result to confirm everything. Should I be worried?

LAST POST Could it be a false positive? Oct 24, 2007

Dear Bob,

My partner who is a HIV+ and I always practise safe sex.

I did a rapid test and the result came in positive. The line on the test kit is very faint. And to comfirm this, my blood was drawn to do a further test in the lab, prob a western blot.

The thing is, i would like to know, Before that test,about 1 hours pior to the test I had some action with my partner. I fingered his anus for play. And later just wash up with normal soap and water.

And the finger they pricked me for the test is the same finger i use for the fingering on my partner.

Could that make the test false positive?

We tried to trace back on when we had sex and we know that we have always have safe sex.

Busy day for that finger. It had butt action and then felt a little prick too!

Regarding the rapid test results, your pretest finger action with your poz partner's backdoor would not affect the test results. However, could your result still be a false positive? Well, since this was a rapid test and since the test line was "very faint" and especially since your HIV risk is negligible, if indeed you "always have safe sex," then yes, your test result could indeed be a "false positive." All positive rapid tests are only considered to be preliminarily positive and require confirmation one way or the other with a more specific confirmatory test.

We'll all keep fingers and toes crossed for you that your preliminary test was indeed "falsely positive." Continue to play safe, OK? I'm here if you or your partner needs me.

Good luck to you both.

Dr. Bob

Response from Dr. Frascino


As anticipated your initial positive test was indeed a "false positive." The blood tests you had drawn to check on your preliminary positive rapid test that are still pending will also be negative, corroborating what we now already know your initial test was a false positive.

Can you now sleep in peace? Absofrickinlutely! Right after you yell WOO-HOO!

Stay safe. Stay well.

Dr. Bob
