Clinical Performance Evaluation of Native Whole Blood Samples of Patients on DOACs With the Perosphere ClotChek™

"Fresh whole blood samples from patients on rivaroxaban or apixaban taken at various times during the day to obtain samples from DOAC patients that represent the entire analytical range to the extent possible, as opposed to a strict trough/peak testing schedule."

Fresh whole blood samples, non-citrated, are drawn and loaded onto a cuvette free of any biological reagents, to obtain a whole blood clotting time value.
