The disproportion between anti-FXa in our NS-FD group to non-proteinuric patients is even higher if compared to patients after orthopedic surgery, with acute medical non-surgical conditions or in healthy volunteers (reported anti-FXa ranged from 0.41 to 0.59 IU/mL) than to our C-FD group (mean anti-FXa 0.33 IU/mL) [24,25,26]. Here, F10 is linked to Fabry disease.
