- AInternational Normalized Ratio (INR)✓ 正解國際標準化比值 (INR)
- BActivated partial thromboplastin time (aPTT)活化部分凝血活酶時間 (aPTT)
- CHemoglobin level血紅素濃度
- DPlatelet count血小板計數

Warfarin 的治療效果透過 INR 進行監測。治療範圍通常設定在 2.0 至 3.0 之間。過低則抗凝血效果不足，過高則有出血風險。aPTT 是用來監測肝素（Heparin）療效的指標，與 Warfarin 無關。
The International Normalized Ratio (INR) is the standardized test used to monitor warfarin therapy, with a typical therapeutic range of 2.0 to 3.0. This measurement ensures adequate anticoagulation while minimizing the risk of bleeding complications.
