You probably have a reactive screening test with a low signal to cutoff ratio and an inderterminate Riba confirmatory test. This means you had a reaction to only one of the 5 Hcv proteins. they are call ns 5, c22, c33, 5-1-1 and Hsod.
There is a chance you are negative. ask your dr for a Pcr qualitative test. this will check for the presence of hep c virus, NOT antibody.
Good luck and don't panic. Try to relax.
What test was it? Have a copy of the lab report?
