Outcome Measures

Primary Outcomes (2)

  • Instrument Evaluation Protocol-PFA100 Instrumentation [platelet function as measured by aperture closure time monitored in seconds for collagen/epinephrine (COL/EPI) cartridges and collagen/ADP (COL/ADP) cartridges]

    This portion of the study is to ensure that the functionality of the instrumentation is working properly. For each participant, their pre-aspirin dose closure times will be compared to their post-aspirin dose closure times. The typical pattern seen in subjects with normal platelet function (pre-aspirin testing) is closure time (CT) results within the reference range for both the COL/EPI and COL/ADP cartridges (normal). In general, the pattern seen after aspirin ingestion is a CT result outside the reference range (abnormal) with COL/EPI and within the reference range for COL/ADP (normal).

    3 months

  • Reference Interval Protocol-PFA100 Instrumentation [platelet function as measured by aperture closure time monitored in seconds for collagen/epinephrine (COL/EPI) cartridges and collagen/ADP (COL/ADP) cartridges]

    For each participant in the non-intervention/placebo arm, platelet function as measured by aperture closure time monitored in seconds for collagen/epinephrine (COL/EPI) cartridges and collagen/ADP (COL/ADP) cartridges will be captured. Following guidelines as stated per CLSI document EP28-A3c, a reference interval will be developed from this captured data.
