I misread you post and thanks to NewLeaf, see that you only had one PCR to date, along with three antibody tests, two positive and one negative.
In that case, I too, would probably feel more secure with a second PCR test down the road, if I could afford it.
Hepatologists are unfortunately relatively rare and in great demand, so it may be difficult to see one with the recent good results you have. I tested positive on a PCR test and it took forever to get an appointment as a new patient. Are you in a major center in India?
You may be in the clear. You may have had the virus but cleared it on your own. I can't guess why the last antibody test would come back negative after 2 positives. If it were me, I might want to do the PCR one more time, off in the future, before I decided that I absolutely no longer had the virus.
Remember that this group has a lot of collective experience, but we are none of us doctors. A hepatologist is the best advisor for you.
I'm not sure I understand your April 2008 results. Did it specifically say negative or positive for detectable virus?
I think the 20 copies/ml PCR test is equivalent to the 50 iu/ml test (20 x 2.7), so that is a decent test, although now there are more sensitive tests. My tests were mostly 50 iu/ml until very, very recently.
Since you went through a second PCR test in September 2008 and it was negative, I would consider myself fine in regards to HCV. I would make sure to be vaccinated for Hepatitis A and B, which are much easier to contract.
Elevated LFT's are indicators and can be caused by several things, including OTC medications, etc. It's a good idea to monitor them in future but not to jump to conclusions about their cause without proper evaluation by a doctor.
