Harmonization of interpretative comments in laboratory hematology reporting: the recommendations of the Working Group on Diagnostic Hematology of the Italian Society of Clinical Chemistry and Clinical Molecular Biology (WGDH-SIBioC).

Abstract

The goal of harmonizing laboratory testing is contributing to improving the quality of patient care and ultimately ameliorating patient outcome. The complete blood and leukocyte differential counts are among the most frequently requested clinical laboratory tests. The morphological assessment of peripheral blood cells (PB) through microscopic examination of properly stained blood smears is still considered a hallmark of laboratory hematology. Nevertheless, a variable inter-observer experience and the different terminology used for characterizing cellular abnormalities both contribute to the current lack of harmonization in blood smear revision. In 2014, the Working Group on Diagnostic Hematology of the Italian Society of Clinical Chemistry and Clinical Molecular Biology (WGDH-SIBioC) conducted a national survey, collecting responses from 78 different Italian laboratories. The results of this survey highlighted a lack of harmonization of interpretative comments in hematology, which prompted the WGDH-SIBioC to develop a project on "Harmonization of interpretative comments in the laboratory hematology report", aimed at identifying appropriate comments and proposing a standardized reporting system. The comments were then revised and updated according to the 2016 revision of the World Health Organization classification of hematologic malignancies. In 2016, the Working Group on Diagnostic Hematology of the Italian Society of Clinical Chemistry and Clinical Molecular Biology (WGDH SIBioC) published its first consensus based recommendation for interpretative comments in laboratory hematology reporting whit the purpose of evaluating comments and the aim to (a) reducing their overall number, (b) standardizing the language, (c) providing information that could be easily comprehended by clinicians and patients, (d) increasing the quality of the clinical information, and (e) suggesting additional diagnostic tests when necessary. This paper represents a review of the recommendations of the former document.
