Would three neg riba tests 15 weeks/18 weeks/35 weeks after a low risk exposure (protected sex with a pros) mean a definite neg outcome for hep c? I also have a neg hcv pcr by rna test 18 weeks after exposure. The riba tests were used after a reactive screening test, 1.0 score. I believe the neg ribas mean neg for antibody and the neg pcr means neg for virus. Is this correct? Thanks for your help, Dr M. You're the best.

I wouldn't have sent the first one so yes - you are certainly negative for HCV testing.
The RIBA is an excellent test for HCV. However, I only use it when I am referred a patient who is at very low risk for HCV but has a positive ELISA test. The RIBA helps to determine if the ELISA was a false positive. That is about the only circumstance in which I use it.
Thanks for your question. I am very glad you like the forum!
