Platelet Function Testing Available at Mayo Clinic Florida

Slide 9

December 2011

In Mayo Clinic Florida, we have several tests available for platelet function testing. All evaluations of platelets should start with a CBC and peripheral blood smear to evaluate platelet number, morphology and granulation, as well as the morphology of the WBCs and RBCs. LTA is the gold standard and is frequently used to evaluate patients with congenital or acquired platelet abnormalities. The VerifyNow test is frequently utilized to detect resistance in patients who receive a loading dose of clopidogrel in preparation for neurosurgery such as a stent placement or for patients who have a thrombotic event while taking clopidogrel. PFA-100 is used in patients who are undergoing surgery and have a history of bleeding. Thromboelastography is used in liver transplant and other critical patients, but our institution does not currently do platelet mapping.
