Conditions
Brief summary
This trial holds minimal risk to the trial volunteers and consists of obtaining whole blood via venipuncture to perform coagulation parameter measurements to define a Normal Reference Range. Written consent to participate in the study will be obtained prior to volunteer screening per site procedures.
Interventions
The TEG® 6s uses the Global Hemostasis with Heparin Neutralization (HN) Cartridge to test the hemostasis properties of citrated blood samples using four different assays/reagents simultaneously, one in each of the four cartridge channels.
Fibrinogen, also known as Factor I, is a plasma protein that can be transformed by thrombin into a fibrin gel (the clot). Fibrinogen is synthesized in the liver and circulates in the plasma as a disulfide-bonded dimer of 3 subunit chains. The biological half-life of plasma fibrinogen is 3 to 5 days.
