Significant values in bold. Normal values: PT=9.7–12.5; aPTT=25–34; R=5–10; alpha=53–72; MA=50–70; lysis=0%–8%.

*Repeat INR performed after reversal in 6 dabigatran, 27 rivaroxaban, and 4 apixaban patients.

†Repeat aPTT performed after reversal in 6 dabigatran, 24 rivaroxaban, and 3 apixaban patients.

‡Repeat TEG performed after reversal in 3 dabigatran, 11 rivaroxaban, and 2 apixaban patients.

INR, international normalized ratio; MA, maximum amplitude; PT, prothrombin time; TEG, thromboelastography; aPTT, activated partial thromboplastin time.
