Abstract
Platelet dysfunction, whether hereditary or acquired, may increase an individual's
risk of spontaneous, posttraumatic, or postoperative bleeding. Conversely, increased
platelet reactivity on antiplatelet agents following vascular (in particular, coronary
vascular) intervention may increase the risk of thrombosis and adverse vascular events.
The aim of platelet function testing is to identify and characterize platelet dysfunction
in these settings to inform bleeding/ thrombosis risk and guide perioperative prophylactic
management strategies. A vast array of screening and diagnostic tests is available
for this purpose. The successful clinical application of platelet function tests depends
on the knowledge of their analytical strengths and limitations and the correct extrapolation
of derived results to a particular clinical scenario. This review critically appraises
traditional and contemporary platelet function testing focusing on their role in clinical
practice.
