Interference Testing in Clinical Chemistry
|Publication Date:||1 April 2018|
Clinical and Laboratory Standards Institute guideline EP07-Interference Testing in Clinical Chemistry is intended to promote uniformity in the evaluation of interference characteristics of medical laboratory measurement procedures. EP07 describes procedures to screen potential interferents, quantify interference effects, and confirm interference in patient samples. This guideline also describes procedures for medical laboratories to verify interference claims and investigate discrepant results caused by unsuspected interferents. Detailed examples are given. EP07 also contains background information on interference testing concepts. Tables of recommended test concentrations for potential interferents can be found in the supplement, CLSI document EP37.1
