What is it indicated for?
The Ultegra Rapid Platelet Function Assay - TRAP (RPFA -TRAP) is a semi-quantitative whole blood platelet function assay used to measure glycoprotein
(GP) lIb/llla receptor blockade in patients treated with abciximab or eptifibatide.
Ultegra RPFA-TRAP results should be interpreted in conjunction with other
clinical and laboratory data available to the clinician.
