Diagnosis of Acute Hepatitis C: anti-HCV or HCV-RNA?

Abstract

Background: In theory, the optimal method for diagnosing acute hepatitis C is nucleotide amplification. This is because of the significant delay in the emergence of hepatitis C virus (HCV) antibodies. We studied whether the use of HCV polymerase chain reaction (PCR) screening for acute HCV infection in a clinical setting would identify otherwise undetected cases. Methods: Patients clinically suspected of having acute viral hepatitis were tested over a 32-month period (n = 2023). Results: Sixty-four patients were found HCV ribonucleic acid (RNA) positive. Of these, 13 were suffering from an acute infection and 12 of these 13 patients were concomitantly anti-HCV (and HCV-RNA) positive at the time of diagnosis. One patient was HCV-RNA positive and anti-HCV negative. This symptom-free patient was tested because of known exposure to HCV 2 weeks previously. Conclusion: Anti-HCV is reliable in screening for acute hepatitis C. In cases of known/possible HCV exposure, we find that HCV PCR is the diagnostic of choice.
