I'm confused my hep c says non-reactive? Then it says signal to cut off 0.04? Then ref range <1.00 what does o.o4 mean?

Cured? From what you describe, your hepatitis C testing sounds negative. This may either reflect: absence of viral infection/exposure, convalescence from a prior infection, response to treatment. Of course, the context of these results is important, so if we could hear more of your circumstance, HealthTap doctors may be more helpful.
