|HCV False Positive
Jul 28, 2006
I recently received an EIA anti-body result of weakly positive with a s/co ratio of 1.05 which is just over the cutoff. My doctor than gave me a HCV-RNA test which came back "not dedectable". I than asked for confirmation with a RIBA but he is reluctant to do so, stating "We are well past that". I am not a IV drug user and have had sex with 4 woman all using condoms (eventhough may have broke with a suspectable woman). Am I stretching it by asking for a confirmation RIBA?
Also, is there a smaller chance of contracting an STD (HCV amongst others) when a condom is used incorrectly, rather than nothing at all.
One more (sorry for the huge question), I believe I was tested for HCV 6 weeks after the initial encounter (it has been 3 years since the encounter) and the test came back negative. I know there is a window period, but also, the testing labs were different (LabCorp vs Quest). Do different labs have different standards when reporting results?
Thank you in advance for your time and effort.

I think that if your laboratory test is positive for hepatitis C, you should get a RIBA test to be certain it is a false positive.
HCV RNA is not detectable in some people who did get hepatitis C and cleared it on their own.
If you have no risk of hepatitis C, then I personally would want to know that the test if a false positive. It may also be important in the future when you want life insurance policy.
Labs vary and test results can vary.
