September 25, 2018
Clinical and Laboratory Standards Institute has published M48—Laboratory Detection and Identification of Mycobacteria.
This guideline covers topics related to laboratory diagnosis of mycobacterial infections.
August 16, 2018
CLSI announces the publication of EP34—Establishing and Verifying an Extended Measuring Interval Through Specimen Dilution and Spiking, 1st ed. EP34 provides recommendations for establishing a dilution scheme to be used for patient specimens that contain measurand concentrations in the extended measuring interval above a measurement procedure’s upper limit of quantitation.
July 25, 2018
The Clinical and Laboratory Standards Institute announces the upcoming publication of QMS22—Management of Paper-based and Electronic Laboratory Information.This guideline is intended to help laboratories meet quality management system requirements for quality system essential (QSE) Information Management.
