title: Evaluation of the fully automated Cobas Core enzyme immunoassay for the quantitation of antibodies against hepatitis B virus surface antigen.
abstract: The Roche Cobas Core automated enzyme immunoassay of antibodies against hepatitis B virus surface antigen (anti-HBs) was evaluated using a protocol complying with the Société Française de Biologie Clinique guidelines. Results showed good precision (CV below 6 and 9% for intra- and inter-assay precision) and accuracy (according to the Paul-Ehrlich-Institute standard); the detection limit of the test was 2 IU/l. The manufacturer's specifications were confirmed and a satisfactory correlation (r = 0.901) was found with an automated method (IMx, Abbott) used for comparison.
