The hepatitis C antibody test costs about$20 and the nucleic acid RNA costs about$100. If you want to check whether there is hepatitis C, you should first check the hepatitis C antibody. If the test is positive for hepatitis C antibody, the diagnosis cannot be confirmed directly, and further investigation of hepatitis C RNA virus quantification is required. Then the next step is antiviral treatment. The treatment for hepatitis C is immediate antiviral treatment once the hepatitis C virus is found to be positive, not based on the liver transaminases rising or not. You also need to check the ultrasound of the liver, gallbladder and spleen to see if it has progressed to cirrhosis or chronic C status.
