CLSI Publishes New Approved Guideline for Use of Mass Spectrometry in the Clinical Laboratory
Wayne, Pennsylvania, USA—November 2007—The development of more user-friendly, affordable, and versatile mass spectrometers, as well as the availability of stable isotopes that serve as internal standards to facilitate more accurate quantification, has allowed a large increase in the use of mass spectrometry (MS) for clinical applications.

Clinical and Laboratory Standards Institute (CLSI) has recently published Mass Spectrometry in the Clinical Laboratory: General Principles and Guidance; Approved Guideline (C50-A) to provide accurate and state-of-the-art information and guidance for the appropriate use of MS in the clinical laboratory. It includes guidance, references, and quality assurance markers that will assist with the implementation and correct operation of an MS system for its many applications.

CLSI Publishes Guideline for Verification of Comparability of Patient Results Within One Health Care System
Wayne, Pennsylvania, USA—November 2007—Patients may go to laboratory testing at multiple locations within a health care system. Continuity of medical care requires that the comparability of test results produced by different measurement systems be verified periodically to provide optimal patient care.

Clinical and Laboratory Standards Institute (CLSI) has recently published a new document, Verification of Comparability of Patient Results Within One Health Care System; Proposed Guideline (C54-P), which provides guidance on how to verify the comparability of quantitative laboratory results for analytes tested on different measurement systems.

CLSI Publishes Updated Standard for Collection of Diagnostic Blood Specimens
Wayne, Pennsylvania, USA—November 2007—Implementing best practices during the collection and handling of blood specimens and fulfilling quality management system requirements during preexamination procedures can reduce errors and will ensure a culture of patient safety within the laboratory.

Clinical and Laboratory Standards Institute (CLSI) has recently updated its document, Procedures for the Collection of Diagnostic Blood Specimens by Venipuncture; Approved Standard—Sixth Edition (H3-A6), which provides a descriptive, stepwise procedure for the collection of diagnostic specimens by venipuncture, including line draws, blood culture collection, and venipuncture in children.
