"Our reluctance to use the bleeding time,
platelet count, prothrombin time and partial thromboplastin
time preoperatively is that such tests expose the
wrong patients, such as the ones with severe hemophilia
or liver disease…The patient who most needs
preoperative detection…is the one with mild
abnormalities.”

Hemostasis testing is used to identify platelet
disorders and diagnose bleeding problems. The tests
include quantitative and functional methodologies.2
Common endpoints for platelet function testing include
time to clot formation and time to cessation of
bleeding. End values in some functional testing
(e.g., bleeding time, prothrombin time) may be subject
to variability based on alterations in the way tests
are performed.3
A variety of different tests are used to assess
hemostatic function. Click on the test below to
