title: A preparation for calibrating the assay of the blood group antibody anti-c.
abstract: A freeze-dried, working calibration preparation (84/628) has been assayed against the International Incomplete anti-c Reference Serum (67/160) in a multi-centre study. The use of 84/628 will avoid the between-laboratory variation, inherent in the use of local preparations, in the reporting of assays of anti-c using the AutoAnalyzer. A value of 13 IU/ampoule has been assigned to the anti-c content of preparation 84/628 which is available from the Blood Group Reference Laboratory, Oxford.
