An international quality control programme for PRISM chemiluminescent immunoassays in blood service and blood product laboratories

Background  Laboratories screening for blood‐borne virus infections in blood and blood products are required by international standards and guidelines to ensure that their testing processes remain within control. An effective means of ensuring this aim is through participation in a quality control programme. Analyses of results from a quality control (QC) programme conducted for the Abbott PRISM (PRISM) assays are reported.
