Reference Range
| Low Molecular Weight Heparin (LMWH): Enoxaparin (Lovenox) |
| (Target Anti-Xa levels measured 4 hours after dosing after 3rd or 4th dose) |
| Low Molecular Weight Heparin Therapeutic Ranges (Full anticoagulation): |
| Therapeutic twice a day dosing or renally adjusted once a day dosing: 0.6-1.0 IU/mL |
| Therapeutic once a day dosing: 1.0-2.0 IU/mL |
| Low Molecular Weight Heparin Thrombosis Prophylaxis (Thromboprophylaxis) Range: |
| 0.2-0.5 IU/mL (Note: Range is for both once a day and twice a day dosing) |
| Unfractionated Heparin (UFH) |
| (Target anti-Xa levels measured 6 hours after initiation or dose adjustment) |
| Unfractionated Heparin Therapeutic Ranges: |
| Venous Thrombosis or Pulmonary Embolism: 0.30-0.70 IU/mL |
| (For patients with venous thrombosis or pulmonary embolism requiring full intensity heparin anticoagulation. Therapeutic range correlates to GBMC heparin protocols: Acute Thrombosis Treatment and Atrial Fibrillation/Peri-operative Bridging.) |
| Moderate Intensity Heparin Anticoagulation: 0.14-0.34 IU/mL |
| (For patients requiring moderate intensity heparin anticoagulation. The GBMC Pharmacy and Therapeutics Committee recommends a lower therapeutic range for cardiac patients with acute coronary syndrome, vascular surgery patients and patients requiring heparin for continuous renal replacement therapy. Therapeutic range correlates to GBMC heparin protocols: Acute Coronary Syndrome, Vascular Post-Operative and Continuous Renal Replacement Therapy.) |
