Implementation of new Westgard rules suggested by the Westgard Advisor software for five immunological parameters.

Introduction: Knowledge and systematic evaluation of analytical errors is the task of internal analytical quality control management. The aim of this study was to assess whether the Westgard rules proposed by Bio-Rad's Westgard Advisor software are more efficient in the monitoring of analytical performance than those previously in use.

Materials And Methods: The study was carried out on the nephelometer Atellica NEPH630 (Siemens Healthineers, Erlangen, Germany).

Utility of serum indices in a particular case of serum protein electrophoresis.

Screening and measurement of monoclonal (M) proteins are commonly performed using capillary zone electrophoresis (CZE). The identification of M-protein or monoclonal component (CM) is an essential requirement for diagnosis and monitoring of monoclonal gammopathies. The detection of CM has been largely improved by CZE.
