Detection of the viral genome in serum is the most reliable way to analyze HCV viremia. In the present study, we evaluated the availability of a new detection kit for HCV-RNA, Amplicor HCV, which is based on the RT-PCR microplate hybridization protocol. The procedure of Amplicor HCV is simple, unlike the conventional RT-nested-PCR method. Although Amplicor HCV assay exhibited the lower sensitivity than the the conventional RT-nested-PCR method (10 x for HCV type 1a, 1b and 2b; 10(3) x for type 2a), Amplicor HCV assay could detect the HCV-RNA in all HCV-RNA positive cases by conventional RT-nested PCR method, except for one case who contained low concentration of HCV-RNA (10 copies/ml). The coincidence rate was 99.2% in 120 clinical samples between two assays. Amplicor HCV assay, moreover, could efficiently evaluate the viremia regardless of anti-HCV-2 antibody titer. This assay was useful for monitoring the effect of interferon therapy during and after administration. These results suggest that Amplicor HCV has an excellent availability for the clinical laboratories.

D006526 Hepatitis C INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.

D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
