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.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
