Postanalytical phase as a modul in EQA - experiences in laboratory haematology

The Committee for External Quality Assessment of Croatian Society of Medical Biochemists was included in the three projects in the field of laboratory haematology, coordinated by the European Organization for External Quality Assurance Providers in Laboratory Medicine (EQALM). One was in the preanalytical phase regarding the stability of the samples for the preparation of blood films for the morphological analysis and two in the postanalytical phase. The postanalytical phase projects were conducted internationally including 151 laboratories in 2010 and 318 laboratories in 2011. The goal was to examine the synchrnization of evaluation of the haematological results on 4 analytical systems (Sysmex, Advia, Cell-Dyn and ABX) in 12 European countries. The original complete blood count (CBC) of the same clinical case from these haematological analyzers was presented. Results from additional analyses, communicating with medical doctors and various laboratory reports were obtained by asking all participants the same questions. The obtained results are presented statistically according to the type of analyzer and to the country that has participated. These show the CBC results depend on the type and performance characteristics of the analytic system ; managenet of the analytic system and the degree of personnel education. There are variations between laboratories in the way they operate and perform standard haematological procedures, particulary regarding analysis and interpretation of the obtained results and taking corrective actions. We have noticed differences which depend upo geographical position of the participant laboratory and differences that depend upon degree of education and organization of health system in each country.
