Not sure what you mean by "inactive hep c".
You either show a detectable viral load or you don't. If you go through acute phase and are one of the 20% who clear the virus on their own, you will always show antibodies. If you have a detectable viral load then the virus is 'active'. Whether or not there is a lot of damage going on varies from person to person depending on a lot of different factors including how well you are taking care of your overall health.
I've only heard of "inactive" described as being in the acute stage. Once it becomes active and moves to the chronic HepC stage, you can pretty much forget about clearing. I don't think anything has been identified as to who will be inactive and clear as opposed to reaching chronic HepC. Some ppl clear when it's 'inactive" or in it's acute stage, the rest of us become chronic HepC carriers or infectees. I think the first signs would be a viral load, but you should probably talk to your doctor.
