The aim of this study was to assess whether the adherence to proper methods of collecting samples for cryoglobulin detection was critical or not on virological parameters in hepatitis C virus (HCV) patients. We studied 56 consecutive patients. Blood samples were collected using a conventional method and a blood collection method at 37\u00b0C adapted to cryoglobulin detection. HCV core antigen and HCV RNA were measured in sera and cryoglobulins issued from both blood collection methods. In cryoglobulin-positive patients, serum concentrations of HCV core antigen, but not that of HCV RNA, were significantly higher when a conventional method was used, compared to a blood collection method at 37\u00b0C (P = 0\u00b7001). In the cryoprecipitates, concentration of HCV core antigen was optimum when the blood collection method at 37\u00b0C, rather than the conventional method, was applied for cryoglobulin detection (P\u2003&amp;lt;\u200310\u22124). The recovery of HCV core antigen in the cryoprecipitate was improved when cryoglobulins were isolated using the blood collection method at 37\u00b0C rather than the conventional method (P\u2003&amp;lt;\u20030\u00b7001). HCV parameter measurements and cryoglobulin study should not be performed on the same serum samples due to the potential impact of blood collection methods on results.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2006.03196.x","type":"journal-article","created":{"date-parts":[[2006,9,27]],"date-time":"2006-09-27T09:42:55Z","timestamp":1159350175000},"page":"211-217","source":"Crossref","is-referenced-by-count":1,"title":["Quantitative measurement of hepatitis C virus core antigen is affected by the presence of cryoglobulins"],"prefix":"10.1093","volume":"146","author":[{"given":"B-N","family":"Pham","sequence":"first","affiliation":[{"name":"D\u00e9partement d'Immunologie Microbiologie des Pathologies Infectieuses, H\u00f4pital Beaujon, Clichy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Martinot-Peignoux","sequence":"additional","affiliation":[{"name":"F\u00e9d\u00e9ration M\u00e9dico-Chirurgicale des Maladies de l'Appareil digestif et INSERM CRB3, H\u00f4pital Beaujon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M-P","family":"Ripault","sequence":"additional","affiliation":[{"name":"F\u00e9d\u00e9ration M\u00e9dico-Chirurgicale des Maladies de l'Appareil digestif et INSERM CRB3, H\u00f4pital Beaujon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N","family":"Boyer","sequence":"additional","affiliation":[{"name":"F\u00e9d\u00e9ration M\u00e9dico-Chirurgicale des Maladies de l'Appareil digestif et INSERM CRB3, H\u00f4pital Beaujon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V","family":"Levy","sequence":"additional","affiliation":[{"name":"Centre d'Investigations Cliniques et INSERM U 717, H\u00f4pital Saint-Louis, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Marcellin","sequence":"additional","affiliation":[{"name":"F\u00e9d\u00e9ration M\u00e9dico-Chirurgicale des Maladies de l'Appareil digestif et INSERM CRB3, H\u00f4pital Beaujon"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2006,9,27]]},"reference":[{"key":"2022010503193905200_b1","doi-asserted-by":"crossref","first-page":"775","DOI":"10.1016\/0002-9343(74)90852-3","article-title":"Biologic and clinical significance of cryoglobulins: a report of 86 cases","volume":"57","author":"Brouet","year":"1974","journal-title":"Am J Med"},{"key":"2022010503193905200_b2","doi-asserted-by":"crossref","first-page":"4","DOI":"10.1136\/jcp.55.1.4","volume":"55","author":"Ferri","year":"2005","journal-title":"Cryoglobulins.
