Anticoagulation Clinics

DuPage Medical Group’s Anticoagulation Clinics are staffed by Registered Nurses or Pharmacists with specific training in anticoagulation monitoring. Patients can have their INR levels checked in a few ways: in-office, with results available within 5 minutes, via lab draws with results phoned to patient the next day and home testing for appropriate patients. When reviewing results with staff, patients will be given any necessary changes in their anticoagulant dose.

Patients can call the nurses during business hours for non-emergent questions or concerns. Most anticoagulation clinic visits will take only 15 – 20 minutes.  

Main Phone Number for ALL Clinics: 630-510-2612
