● Recommended to monitor using chromogenic antifactor Xa assay on specimens obtained up to 4 hours after subcutaneous injection of LMWH (Chest 2001;119(1 Suppl):64S)
● Recommended to use different calibrations for LMWH and unfractionated heparin, and to establish calibration curves for each lot and type of LMWH
● Donít use PTT to monitor because LMWH doesnít affect thrombin or factor IXa
