Use the following procedure to calculate percent inhibition.
NOTE: A sample taken prior to abciximab or eptifibitide administration cannot be used to establish a “baseline” or
uninhibited result if a GP IIb/IIIa inhibitor has been administered within the past 10 days.
1. Press the Percent key.

2. Obtain the patient’s baseline (pre-drug) PAU result. Enter the baseline PAU result in the space
indicated “Here”, press the Tab key, and re-enter the baseline PAU result in the space indicated
“AND here” (Figure 6-17). Press the Next key to display the percent inhibition. In the example
(Figure 6-18), if the baseline result was 328 PAU and the post-drug result was 16 PAU, this would
calculate to 95% inhibition.
