Key result
A one-stage PCR followed by a liquid hybridisation assay demonstrated sensitivity comparable to nested PCR for detecting HCV-RNA, offering an easier method with fewer contamination problems.
Why the study?
Does a one-stage PCR followed by a liquid hybridisation assay accurately detect HCV-RNA compared to RIBA and nested PCR in anti-HCV-positive patients?

Does a one-stage PCR followed by a liquid hybridisation assay accurately detect HCV-RNA compared to RIBA and nested PCR in anti-HCV-positive patients?
A one-stage PCR followed by a liquid hybridisation assay offers comparable sensitivity to nested PCR for HCV RNA detection, with fewer contamination problems.
May simplify HCV RNA detection in labs; leaves open validation before routine clinical use.
A one-stage polymerase chain reaction (PCR) followed by an automated liquid hybridisation assay was used to examine anti-HCV-positive patients. The presence of HCV-RNA in 251 randomly selected enzyme immunoassay (EIA) positive clinical specimens was compared to their RIBA pattern. An association of a RIBA pattern with presence or absence of HCV-RNA was not detected. One hundred of these samples were also evaluated after dividing them into normal and elevated serum alanin aminotransferase (ALT) levels. PCR results were obtained on the basis of amplification products from two different gene regions (5'-NC region and NS 3). To prove the specificity of the PCR products, a commercially available digoxigenin-based liquid hybridisation assay was evaluated. The sensitivity was comparable to the results obtained after nested PCR. Based on the results of the study, the two-stage PCR can be changed in favour of the easier one-step PCR which offers the advantage of fewer contamination problems.

Schacker et al. (1995) conducted a cross-sectional in Hepatitis C (anti-HCV-positive) (n=251). One-stage PCR followed by automated liquid hybridisation assay vs. RIBA pattern and nested PCR was evaluated on Presence of HCV-RNA compared to RIBA pattern and sensitivity compared to nested PCR. A one-stage PCR followed by a liquid hybridisation assay demonstrated sensitivity comparable to nested PCR for detecting HCV-RNA, offering an easier method with fewer contamination problems.
