Diagnosis of Hepatitis C Virus Infection

You answered:

B Recombinant immunoblot assay (RIBA) for HCV antibody

This answer is incorrect. In a person with a positive screening test (in this case, EIA for HCV antibody), a positive recombinant immunoblot assay (RIBA) result proves this person had HCV infection at some point in the past. A negative result means that the screening test was falsely positive. A positive RIBA does not tell us if the patient has active HCV infection, and is probably unnecessary in this patient since we already know he has an elevated ALT.

Choose another answer:

A Repeat of the enzyme immunoassay (EIA) test for HCV antibody
C Alpha-fetoprotein level
D HCV RNA test
