Hepatitis C virus (HCV) RNA and infectious virions have been detected in association with the cellular components of blood of patients with active liver disease; however, studies comparing HCV viral loads in whole blood and plasma have generated contradictory results. The aim of this study was to investigate the distribution of HCV in different compartments of the peripheral blood from HCV\u2010infected blood donors, which may differ from that observed in patients with HCV\u2010associated liver disease.<\/jats:p><jats:p><jats:bold>Materials and Methods\u2002<\/jats:bold>Hepatitis C virus\u2010positive donor specimens were identified by NAT and antibody testing. HCV RNA was extracted from samples of whole blood and their corresponding components (RBC and plasma). Viral RNA was quantified by real\u2010time qRT\u2010PCR.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold>Hepatitis C virus was present in all blood components from infected donors from which RNA could be amplified. For the majority of samples, plasma (34\/46) had the highest detectable concentration of HCV RNA, and RBC (37\/46) had the lowest. Specimens with negative NAT and positive antibody assays also produced qRT\u2010PCR negative results.<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold>These results indicate that including the RBC fraction in the tested sample will not increase assay sensitivity. Although 10% of the specimens had a higher viral load in whole blood, there was no significant overall increase in sensitivity to justify changes in the specimen format. Thus, plasma specimens are well suited for blood donor screening for HCV.<\/jats:p>","DOI":"10.1111\/j.1423-0410.2012.01598.x","type":"journal-article","created":{"date-parts":[[2012,3,9]],"date-time":"2012-03-09T18:55:54Z","timestamp":1331319354000},"page":"99-106","source":"Crossref","is-referenced-by-count":1,"title":["Distribution of hepatitis C virus in circulating blood components from blood donors"],"prefix":"10.1111","volume":"103","author":[{"given":"C.","family":"Chancey","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Winkelman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
