Magali DECHOMET and Christine LOMBARD
EQA performed since 2012
Number of participating laboratories in 2022: 433
1 - Scheme Overview
This external quality assessment scheme provides normal and disease-related electrophoretic profiles for assessing monoclonal gammopathy (paraproteinemia) diagnosis and type determination.
The reports include statistical processing of quantitative results and the analysis of qualitative results: interpretation of electrophoresis, immunofixation and immunotyping performed to identify a monoclonal band detected by electrophoresis.
Participating labs can choose to be assessed for all the analytes of this scheme, or simply a subset of analytes of interest.
