This is the single most important test to take after you are diagnosed with Hepatitis C. The HCV Genotyping test is a one-time test that identifies the exact strain (or genotype 1-6) of the virus you have. This is the master key your doctor needs to prescribe the correct, modern antiviral medication. Different genotypes respond to different drugs. A simple blood draw is required. This test is the non-negotiable first step to a cure. It ensures you get the right, personalized treatment plan from day one, maximizing your chance of success.
