WA Anticoagulation Medication Chart

For facilities that treat adult patients

Please note:
Each hospital is required to check with their Pathology laboratory to determine the hospital specific therapeutic target range for unfractionated heparin against a gold standard test (e.g. residual anti-Xa activity).
Because of this hospitals should not use a WA Anticoagulation Chart from another hospital as aPTT target ranges will change from hospital to hospital.
