Abstract
Specimen integrity is important for every laboratory test, but especially for coagulation testing, where even minor deviations from standard practices may lead to inaccurate results. Citrated plasma is the most common specimen type for routine and special coagulation testing, and the suitability of citrated plasma is particularly sensitive to anticoagulant concentration, container materials, collection technique, centrifugation, and storage. Accordingly, this chapter will emphasize citrated plasma specimens, but will also address other specimen types that are becoming increasingly important in hemostasis testing. The purpose of this chapter is to describe current recommendations for and points of ambiguity about specimens for hemostasis testing to assist the laboratory director in establishing standard operating procedures and evaluating the acceptability of non-ideal specimens.
