[Circadian behavior of the fibrinogen concentration in the plasma]
Abstract:
The concentration of the fibrinogen in the plasmas was determined in the course of a day (circadian rhythm) as well as in different position of the body. During the night hours a concentration minimum existed at 24.00 o'clock or at 4.00 o'clock, which however, could not be explained by the position of the body alone, which had changed in comparison to day-time. The time of the blood-taking and the position of the body must be taken into consideration in the interpretation of the laboratory values.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
