Guidelines for setting up an external quality assessment scheme for blood smear interpretation. Part II: survey preparation, statistical evaluation and reporting.
Blood smear analysis is a well-known technique in medical laboratories. The clinical relevance of this analysis and its interpretation are very important. Consequently, monitoring of laboratory performance by an external quality assessment scheme is strongly recommended. This article represents a very practical guidance document for External Quality Assessment Scheme (EQAS) organizers for setting up blood smear schemes. In the first part of the guidelines, the Hematology Working Group of the European External Committee for External Quality Assurance Programmes in Laboratory Medicine (EQALM) published practical information for the preparation of blood smears for use in an EQAS. Part II focuses on aspects such as survey preparation, statistical evaluation and reporting, and describes particular details for organizing blood morphology EQA surveys by means of virtual microscopy.
