3% of chronic HCV patients don't seroconvert?
May 19, 2012
I have read in several places that 97% of people will show HCV antibodies by 6 months, and other information that mentions 3% of chronic HCV patients never show antibodies. Also, I have seen several of your posts that state most people will show antibodies by 3 months, with some outliers taking up to 6 months. In what situations would someone not seroconvert at all or take longer than 6 months?
I had unprotected anal sex with another man over 7 months ago, and I have been freaking out since. I had negative HIV antibody tests at 2, 3, 6, and 7 months, and negative HCV antibody tests at 2 and 7 months. Also, negative for other STDs at 2 and 7 months. Is any more testing necessary? If both HIV and HCV antibody tests are negative at 7 months, is this completely conclusive?

Yes your testing is conclusive because both tests are negative. Great news!
You are correct in surmising that most people seroconvert by 12 weeks; a minority of patients take longer (up to six months). Anyone who takes longer than that are few in number. Having underlying HIV infection can delay antibody formation.
