Groups 1 and 2 were donor samples that gave positive or indeterminate band patterns, respectively, when originally tested on the HCV Western blot between 1994 and 1998. These samples were tested on the RIBA 3.0. Donor samples in Groups 3 and 4 were originally tested on RIBA\u20103 during 1998 and 1999 and gave positive or indeterminate blot results, respectively. In this study these two groups were tested on the HCV Western blot. Samples with discrepant results on the two immunoblot assays were selected for genotyping or serotyping.<\/jats:p><jats:p> <jats:bold>RESULTS<\/jats:bold> : The two immunoblots showed similar sensitivity to the core and NS5 proteins. However, of 35 samples positive on Western blot or RIBA\u20103, the Western blot failed to detect NS4 in 14 samples compared with only 5 for RIBA\u20103. As well, the Western blot failed to detect NS3 in 6 samples compared to 2 for RIBA\u20103. Five (27.8%) of 18 samples that were Western blot indeterminate due to core reactivity showed an additional NS3 band on RIBA\u20103. Of the samples with additional NS3 and\/or NS4 reactivity on RIBA\u20103 that were genotyped or serotyped, all were HCV type 3.<\/jats:p><jats:p> <jats:bold>CONCLUSIONS<\/jats:bold> : Western blot and RIBA\u20103 showed similar sensitivity to the HCV core and NS5 proteins. However, RIBA\u20103 showed greater sensitivity to both NS3 and NS4 compared to the Western blot. The reduced sensitivity of the Western blot to the NS3 and NS4 proteins was observed with HCV type 3 samples.<\/jats:p>","DOI":"10.1046\/j.1537-2995.2002.00153.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T22:50:24Z","timestamp":1047509424000},"page":"1053-1058","source":"Crossref","is-referenced-by-count":6,"title":["Anti\u2010HCV confirmatory testing of voluntary blood donors: comparison of the sensitivity of two immunoblot\u2003assays"],"prefix":"10.1111","volume":"42","author":[{"given":"Philip R.","family":"Kiely","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leo A.","family":"Eliades","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mekonnen","family":"Kebede","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew D.","family":"Stephenson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Darren K.","family":"Jardine","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2002,8,28]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.1890460408"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0163-4453(95)90854-4"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1996.36596338024.x"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/25.3.674"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-9071(199606)49:2<132::AID-JMV10>3.0.CO;2-G"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1997.37297203524.x"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.1890430206"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1994.34694295070.x"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01982183"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/hep.510260709"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-8278(94)80231-9"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1423-0410.1996.tb01311.x"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1995.351096026366.x"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.2000.40070867.x"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1423-0410.1998.7440217.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1994.34994378281.x"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1995.35996029158.x"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.1890430312"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.2000.40080917.x"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0168-8278(96)80183-8"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1423-0410.1998.7510032.x"},{"key":"e_1_2_6_23_2","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1128\/jcm.34.1.80-83.1996","article-title":"Significance of indeterminate third\u2010generation hepatitis C virus recombinant immunoblot assay.","volume":"34","author":"Pawlotsky J\u2010M","year":"1996","journal-title":"J Clin Microbiol"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2893.1997.00060.x"},{"key":"e_1_2_6_25_2","doi-asserted-by":"publisher","DOI":"10.1080\/00313029800169226"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1746.1998.tb00761.x"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1996.36696269515.x"},{"key":"e_1_2_6_28_2","unstructured":"HCV immunoassays and antigen preparations.
