[Monoclonal immunoglobulin: national external quality assessment and diagnostic reasoning].


In 2003, for the scheme of the French national external quality assessment, Afssaps sent to medical laboratories a sample for which two analyses could be carried out: the electrophoresis of proteins and the characterization for monoclonal immunoglobulin. The purpose of this new approach was to make it possible to the laboratories to transpose their usual diagnostic reasoning. This survey recalled to the biologists that it is necessary to check the sensitivity of the test of electrophoresis of proteins used in first intention and to use advisedly the anti-serums anti-free chains. Moreover this operation reinforced the educational aspect of the external quality assessment, pointing out the importance to ensure the coherence of the results of these two analyses carried out with a same diagnostic aim.
