Quality Control Scheme

The results from an external quality control scheme for the assay of paracetamol in serum are reported. A preferential method of assay has not become evident, but, as a result of the scheme, some laboratories have changed or modified their techniques or have re-established the limits of detection. The majority of laboratories were able to estimate paracetamol satisfactorily at those levels which are of clinical importance. The overall group performance has shown little change. The programme has had considerable impact in so far as it has led to a mutually useful interchange of information and trouble shooting.

Abstract Context.—The first national quality control (QC) program of histocompatibility serum testing was performed in Italy in 2002. Objective.—To monitor the performance of HLA typing laboratories while meeting the accreditation requirements of the European Federation for Immunogenetics (EFI), which require HLA typing laboratories to participate in external QC of their crossmatch and antibody analyses. Design.—The Turin Transplant Immunology Service was asked to organize a QC survey of 17 HLA typing laboratories in Italy. Each laboratory received 12 serum specimens and 6 blood samples and was required to perform 36 crossmatches and 12 serum antibody specificity determinations. Settings.—Data of participating centers were compared to establish whether EFI requirements were satisfied. Results.—In crossmatch analysis, the results of 32 of 36 crossmatches reached the 75% consensus target, with all the participating laboratories meeting the standards of the EFI. In antibody analysis, only 7 of 17 laboratories met the EFI standards. Conclusion.—The first Italian QC program shows that the participating laboratories obtained consistent results in crossmatching, whereas the results were less satisfactory in the determination of serum antibody specificity, where consensus was reached only with monospecific sera and antibody-negative samples.

Abstract A quality control program utilizing both "known" and "blind" control specimens was analyzed in the routine clinical chemistry laboratory. The results obtained with the control samples of 18 automated and nonautomated procedures demonstrated the presence of analytical bias. Only through the evaluation of blind control samples tested at random times can a reliable measure of the proficiency of the laboratory be achieved.

SUMMARYTwo statistical analyses are suggested to compare the success rates in isolating and identifying pathogenic organisms from specimens achieved by different laboratories participating in a quality control scheme. An example is given in which the analyses are applied to 25 laboratories that received 30 simulated specimens.
