CLSI Publishes Guideline for the Collection, Transport, and Processing of Blood Specimens for Coagulation Assays

WAYNE, Pa.--(Business Wire)--
The reliability and accuracy of coagulation test results depend
upon a variety of variables, including anticoagulant volume and
concentration, type of tube additive, duration and temperature of
specimen storage, and surface of containers used for specimen
collection and storage.

   Because of the many variables that can affect coagulation test
results, Clinical and Laboratory Standards Institute (CLSI, formerly
NCCLS) recently published an updated guideline, Collection, Transport,
and Processing of Blood Specimens for Testing Plasma-Based Coagulation
Assays and Molecular Hemostasis Assays; Approved Guideline--Fifth
Edition (H21-A5), which provides procedures for collecting,
transporting, and storing blood; processing blood specimens; storing
plasma for coagulation testing; and general recommendations for
performing the tests.

   This document replaces the fourth edition approved guideline,
H21-A4, which was published in 2003. Changes in this edition of the
document include:

   --  revised transportation and storage guidelines for plasma-based
        hemostasis testing; and

   --  addition of information pertinent to the collection,
        transportation, and processing of specimens for molecular
        hemostasis assays.

   The intended users of this guideline are laboratory and/or
clinical personnel responsible for obtaining patient specimens and
preparing samples for plasma-based or molecular coagulation testing.
It is also aimed at manufacturers of products involved in specimen
collection, storage, preparation, and testing of plasma-based or
molecular hemostasis assays.
