Test ID DABIE Dabigatran, Ecarin, Plasma

Ordering Guidance

This test measures dabigatran only. For measurement of aragatroban direct thrombin inhibitor, see ARGAT / Argatroban, Ecarin, Plasma.


This test is not indicated for monitoring low molecular weight heparin (LMWH), unfractionated heparin (UFH), or oral direct anti-Xa inhibitors (eg, apixaban, rivaroxaban, edoxaban). For monitoring oral direct anti-Xa inhibitors, see APIXA / Apixaban, Anti-Xa, Plasma; EDOXA / Edoxaban, Anti-Xa, Plasma, or RIVAR / Rivaroxaban, Anti-Xa, Plasma.

Necessary Information

If priority specimen, mark request form, give reason, and request a call-back.

Specimen Required

Specimen Type: Platelet-poor plasma

Collection Container/Tube: Light-blue top (3.2% sodium citrate)

Submission Container/Tube: Plastic vial

Specimen Volume: 1 mL

Collection Instructions:

1. Specimen should be drawn 1 to 3 hours (peak) after a dose or just prior (trough) to the next dose for dabigatran concentrations.

2. For complete instructions, see Coagulation Guidelines for Specimen Handling and Processing in Special Instructions.

3. Centrifuge, transfer all plasma into a plastic vial, and centrifuge plasma again.

4. Aliquot plasma into a plastic vial leaving 0.25 mL in the bottom of centrifuged vial.

5. Freeze plasma immediately (no longer than 4 hours after collection) at -20° C or, ideally, ≤-40° C.

Additional Information:

1. Double-centrifuged specimen is critical for accurate results as platelet contamination may cause spurious results.

2. Each coagulation assay requested should have its own vial.

Useful For

Measuring dabigatran concentration in plasma


This assay is not useful for measurement of other direct thrombin inhibitors eg, argatroban or bivalirudin.
