EQALM recommendations for the analytical performance specifications for blood smear interpretation in haematology: a need for standardization.
Objectives: The European Organization for External Quality Assurance Providers in Laboratory Medicine (EQALM) Haematology Working Group (WG) has previously provided two guidelines to support the standardization of haematology blood smear external quality assessment (EQA) (Vives CJL, Albarède S, Flandrin G, Heller S, Horvath K, Houwen B, et al. Guidelines for blood smear preparation and staining procedure for setting up an external quality assessment scheme for blood smear interpretation. Part I: control material. Clin Chem Lab Med 2004;42:922-6; Vives CJL, Van Blerk M, Albarède S, Gutierrez G, Heller S, Nordin G, et al. Guidelines for setting up an external quality assessment scheme for blood smear interpretation. Part II: survey preparation, statistical evaluation and reporting. Clin Chem Lab Med 2006;44:1039-43) but these recommendations did not include analytical performance specifications. In this paper the WG provides advice on the performance specifications for the evaluation of blood cell identification, comments on morphological characteristics and diagnostic hypothesis.
Methods: To develop these specifications, the WG made a survey of the practices in use by EQALM members and provided a standard set of EQA data, provided by one of the members, for performance evaluation.
Results: The results of this exercise show a variation in the performance assessment outcomes from one EQA provider to another, suggesting that a degree of standardisation would be of benefit to participating laboratories.
Conclusions: The WG has provided advice on common performance specifications, based on model 1 of the Milan Consensus (Sandberg S, Fraser CG, Horvath AR, Jansen R, Jones G, Oosterhuis W, et al. Defining analytical performance specifications: consensus statement from the 1st strategic conference of the European federation of clinical chemistry and laboratory medicine. Clin Chem Lab Med 2015;53:833-5).
