Outcome Measures
Primary Outcomes (1)
Distribution and variability of WBCT measurements
Assessment of the analytical measurement range, reproducibility and precision of WBCT measurement in human blood spiked with predetermined concentrations of enoxparin and edoxaban
1 day
Study Arms (1)
Blood Sample
Blood will be sampled by direct venipuncture on 8 occasions.
Interventions
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.
Eligibility Criteria
healthy volunteers
You may qualify if:
- Signed and dated informed consent form
- Healthy male and female subjects aged 18 to 65 years (inclusive) with suitable veins for venipuncture -
You may not qualify if:
- Subjects who cannot communicate reliably with the Investigator
- History of major bleeding or major trauma within the 6 months prior to signing informed consent
- Propensity to bleeding (i.e. due to recent trauma, surgery, peptic ulcer, gastrointestinal bleeding or hemorrhoids)
- Significant infection or known inflammatory process in the 2 weeks prior to screening
- Active smoker or current use of any tobacco products or use within 3 months prior to signing informed consent
- Treatment with any investigation product or therapy within 30 days prior to screening
- Received non-steroidal antiinflammatory drugs or medications (including anticoagulants or aspirin) with a direct effect on hemostasis within 7 days of blood sampling
- Unwilling to comply with the procedures in the protocol
- Currently enrolled in any other study -
