Interference Testing in Clinical Chemistry (EP7-A2)

EP7-A2—Interference Testing in Clinical Chemistry; Approved Guideline—Second Edition
Promoting uniformity in evaluating interference characteristics in clinical laboratory measurement procedures, EP7 describes procedures for manufacturers to screen potentially interfering substances, quantify interference effects, and confirm interference in patient samples. The guideline also describes procedures for clinical laboratories to verify interference claims, and to investigate discrepant results caused by unsuspected interfering substances.  Includes background information on interference testing concepts, tables of recommended test concentrations for analytes and potential interference, and data collection and analysis worksheets.

Our procedures have been designed to ensure that consensus has been achieved when a standard or guideline is published at the approved level. This means that a document has been rigorously reviewed by the authoring subcommittee, the area committee overseeing the project, the Board of Directors, and the medical-testing community which participates in the consensus process by carefully reviewing and commenting on the standard or guideline.
