Indicators
The term "vitamin K" refers to a group of chemically similar fat-soluble compounds called naphthoquinones: vitamin K1 (phytonadione) is found in plants and is the primary source of vitamin K for humans through dietary consumption, vitamin K2 compounds (menaquinones) are made by bacteria in the human gut, and vitamin K3 (menadione) is a water-soluble preparation available for adults only. Vitamin K is necessary for the liver to produce the coagulation factors II, VII, IX, and X, as well as the clotting factors protein C, protein S, and protein Z; vitamin K deficiency can result in deficiencies of these coagulation factors and excess bleeding. An injection of vitamin K is routinely given to newborn infants to prevent vitamin K deficiency bleeding, also known as hemorrhagic disease of the newborn. Vitamin K deficiency is rare in adults but may result from chronic malnutrition or an inability to absorb dietary vitamins.
Tests
The determination of the biological activity of von Willebrand coagulation factor cleaving protease, ADAMTS13, in a sample.
Indicators
von Willebrand factor (2813 aa, ~309 kDa) is encoded by the human VWF gene. This protein is involved in platelet adhesion and blood coagulation.
Indicators
This gene plays a role in regulation of transcription. It is involved in the control of both cell differentiation and proliferation.
