Abstract:
BACKGROUND: To determine the positivity of hepatitis C virus-ribonucleic acid (HCV-RNA), we tested blood specimens of donor both positive in enzyme immunoassay (EIA) and in immunoblot assay, and those positive in EIA but indeterminate in immunoblot assay by nucleic acid amplification test (NAT). After quantifying HCV-RNA of specimens positive in NAT, we compared the titers of HCV-RNA between blood donor group and patient group. METHOD: One hundred twenty blood specimens positive both in screening test and in confirmative test, and 20 specimens positive in screening test but indeterminate were tested by qualifying NAT. After testing the specimens positive in this test by quantifying NAT, we classified specimens into 3 groups, normal group whose ALT values were within 45 IU/L, abnormal group whose values were higher than 45 IU/L and patient group who admitted into hospital to treat chronic hepatitis C and then compared HCV-RNA among groups. RESULTS: 81% of specimens both positive in screening test and in confirmative test was positive in NAT. Only 10% of specimens positive in screening test but indeterminate in confirmative test was positive in NAT. Ages of patient group were highest among groups and titers of HCV-RNA of patient group were lower than any other group. Correlation of AST/ALT values with the titers of HCV-RNA was not shown. CONCLUSION: It is concluded that the study groups show no difference of HCV-RNA titers whether they have symptoms of liver disease or not. The titer of HCV-RNA has no correlation with AST/ALT values.
