Abstract

Hemostasis testing performed in clinical laboratories are critical for assessing hemorrhagic and thrombotic disorders. The assays performed can be used to provide the information required for diagnosis, risk assessment, efficacy of therapy, and therapeutic monitoring. As such, hemostasis tests should be performed to the highest level of quality, including the standardization, implementation, and monitoring of all phases of the testing, which include the preanalytical, analytical, and post-analytical phases. It is well established that the preanalytical phase is the most critical component of the testing process, being the hands-on activities, including patient preparation for blood collection, as well as the actual blood collection, including sample identification and the post-collection handling to include sample transportation, processing, and storage of samples when testing is not performed immediately. The purpose of this article is to provide an update to the previous edition of coagulation testing-related preanalytical variables (PAV) and, when properly addressed and performed, can reduce the most common causes of errors in the hemostasis laboratory.
