Dabigatran Reversal Idarucizumab Threshold Calculator

Determine idarucizumab (Praxbind) dosing threshold for emergency dabigatran reversal based on dTT, ecarin clotting time, or anti-IIa activity, and indication (life-threatening bleeding or urgent surgery).

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Determine idarucizumab (Praxbind) dosing threshold for emergency dabigatran reversal based on dTT, ecarin clotting time, or anti-IIa activity, and indication (life-threatening bleeding or urgent surgery)

Each component has a specific meaning:

  • DTT — The dtt recorded for the scenario being assessed.
  • Ecarin clotting time — The ecarin clotting time recorded for the scenario being assessed.
  • Or anti-IIa activity — The or anti-iia activity recorded for the scenario being assessed.
  • Indication — The indication recorded for the scenario being assessed.

Note: Interpret the dabigatran reversal threshold result against the thresholds and context described above.

How to Use

Enter the dTT, ecarin clotting time, or anti-IIa activity, indication for the scenario you are assessing. Determine idarucizumab (Praxbind) dosing threshold for emergency dabigatran reversal based on dTT, ecarin clotting time, or anti-IIa activity, and indication (life-threatening bleeding or urgent surgery). Use the dabigatran reversal threshold result to inform your calculation.
