blood protein measurement in vitro coagulation measurement blood fibrinogen level 2010-06-10T11:07:51Z CMO:0000209 EFO:0004623 Factor I level Measurement of the amount of fibrinogen in blood, the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. Fibrinogen is a glycoprotein comprised of three pairs of nonidentical polypeptide chains; cleavage products of fibrinogen have a major role in blood clotting as well as roles in cell adhesion and spreading, display vasoconstrictor activity, and can function as chemotactic and mitogenic agents for several cell types. clinical_measurement_ontology fibrinogen measurement mshimoyama
