Surgical programs depend on it
No surgery proceeds without PT/INR clearance. When reagents run out or expire, surgical schedules collapse. Operating room time gets wasted. Patients who prepared for procedures go home without treatment.
Anticoagulation clinics need consistency
Warfarin patients require regular INR monitoring. Heparin therapy needs APTT tracking. These patients can't wait for reagent backorders - inconsistent supply means inconsistent care.
Emergency departments can't delay
Trauma patients need immediate coagulation assessment. Bleeding emergencies require rapid fibrinogen results. When reagents aren't available, treatment decisions get made without critical information.
