|Condition or disease||Intervention/treatment|
|Healthy||Other: Blood drawn by direct venipuncture Drug: edoxaban Drug: Enoxaparin Drug: Saline sham|
Twelve healthy volunteers aged 18 to 65 years (6 subjects per spiking anticoagulant) will be enrolled. A total of 8 blood samples (12 mL/sample) will be collected by direct venipuncture. The samples from will be spiked with predetermined concentrations of edoxaban or enoxaparin (baseline, saline control and 6 specified concentrations of anticoagulant).
Each blood sample will be tested for whole blood clotting time (WBCT), Point of Care activated partial thromboplastin time (aPTT) and prothrombin time (PT).

Blood will be sampled by direct venipuncture on 8 occasions.
Other: Blood drawn by direct venipuncture
Subjects will have blood sampled (12 mL/sample) a total of 8 times by direct venipuncture. Samples will be spiked with predetermined concentrations of anticoagulants, or saline sham.
Drug: Saline sham
- Distribution and variability of WBCT measurements [ Time Frame: 1 day ]Assessment of the analytical measurement range, reproducibility and precision of WBCT measurement in human blood spiked with predetermined concentrations of enoxparin and edoxaban
