Summary

The pre-analytical phase of hemostasis testing is the phase of testing that is most prone to errors that may impact laboratory assay results. The effect on results can be clinically significant and can therefore impact patient management leading to mistaken diagnosis and treatment. Knowledge of and adherence to guidelines on proper sample collection and processing is therefore paramount to providing accurate and reliable hemostasis laboratory results. This chapter reviews the variables associated with specimen collection, transportation, processing, and storage, the guidelines that should be followed, and provides information as to the potential impact of these variables.
