In patients receiving anticoagulation therapy, what should be closely monitored?

Monitoring INR (International Normalized Ratio) or aPTT (activated Partial Thromboplastin Time) levels is crucial for patients receiving anticoagulation therapy because these tests assess the effectiveness and safety of the anticoagulant medication. INR is primarily used for patients on warfarin, while aPTT is utilized for those on heparin. Maintaining the appropriate therapeutic range is essential to minimize the risk of thrombosis (if under-anticoagulated) or bleeding complications (if over-anticoagulated).

Regularly checking these levels allows healthcare providers to adjust the dosage accordingly and ensures that patients benefit from anticoagulation therapy while minimizing adverse effects. This close monitoring is a key part of safe anticoagulant management and is integral to patient care in various clinical settings.
