#M3338: Dabigatran (Pradaxa) Level by ECT COMPONENTS Name Method Ref Range Units Panic Value Frequency Method Description Dabigatran (Pradaxa) Level by ECT Clottable <0.01 ug/mL M, T, W, Th, F, Sat, Sun Ecarin Clotting Time SPECIMEN REQUIREMENTS Name Type Volume Aliquot # Temp Container Type Primary/ Alternate Dabigatran (Pradaxa) Level by ECT Citrated Plasma 1.0mL 1 Frozen Blue Top GENERAL INFORMATION Abbreviations ECT Test Frequency M, T, W, Th, F, Sat, Sun Alternate Names Ecarin Clotting Time, Dabigatran Level, Pradaxa Level CPT Code 85635 Notes The Ecarin Clotting Time (ECT) is insensitive to the presence of heparins, warfarin, lupus anticoagulants and factor levels while being the most sensitive test to very small amounts of Dabigatran. A therapeutic range for Dabigatran (PRADAXA) has yet to be established; however, in normal plasma Dabigatran is not detectable (<0.01µg/mL). This test is recommended for the documentation of the absence of Dabigatran in the bleeding patient and prior to surgery. Machaon Diagnostics is the only reference lab in the US to result a plasma Pradaxa level within 24 hours. In emergent situations, a result can be released 2 hours after a sample has been received by our Oakland-based lab. Our ultra-fast reporting format allows for significantly safer dosing, wash-out and management of patients receiving Pradaxa.
