CLSI C42 Abstract

Erythrocyte Protoporphyrin Testing; Approved Guideline (CLSI document C42-A) is a comprehensive document for use by laboratorians who perform erythrocyte protoporphyrin (EP) determinations; its aim is to reduce/eliminate the lack of uniformity in current measurement practices. The biochemistry and pathology of EP are discussed, the history of EP determinations is summarized, and the applications of the test are defined. The document recommends the adoption of a specific molar absorptivity constant for the standardization of EP methods and the universal adoption of reporting units expressed as the molar ratio of protoporphyrin to heme. Detailed methods for the measurement of EP by extraction and hematofluorometry are included, and the interpretation of EP results is discussed.
