: A 64-year-old female is being treated with warfarin for atrial fibrillation and presents for routine evaluation. A TEG is performed to assess her coagulation status. The TEG results are as follows: R = 15 minutes (prolonged) K = 5 minutes (prolonged) α-Angle = 30° (decreased) MA = 45 mm (reduced) LY30 = 4% (normal) Questions: How do the TEG results relate to the patient’s warfarin therapy? What are the key TEG parameters that indicate that the patient is over-anticoagulated? What would be the next step in managing this patient’s anticoagulation?
