What are the 12 blood clotting factors?
The following are coagulation factors and their common names:
- Factor I – fibrinogen.
- Factor II – prothrombin.
- Factor III – tissue thromboplastin (tissue factor)
- Factor IV – ionized calcium ( Ca++ )
- Factor V – labile factor or proaccelerin.
- Factor VI – unassigned.
- Factor VII – stable factor or proconvertin.
What are the 13 factors responsible for blood clotting?
The clotting factors are Factor I (fibrinogen), Factor II (prothrombin), Factor III (tissue thromboplastin or tissue factor), Factor IV (ionized calcium), Factor V (labile factor or proaccelerin), Factor VII (stable factor or proconvertin), and Factor VIII (antihemophilic factor).

What is factor 7 used for?
Factor VII, also called proconvertin, is one such clotting factor produced by the liver. It requires vitamin K for its production. Along with other clotting factors and blood cells, it promotes blood clotting at the site of an injury. It forms normal blood clots and closes the wound to prevent blood loss.
What is Factor 4 in blood coagulation?
Clotting factor IV is a calcium ion that plays an important role in all 3 pathways. Some of the clotting factors function as serine proteases, specifically factors II, VI, IX, and X.
What is factor 7 called?
Clotting Factor VII Factor VII, also called proconvertin, is one such clotting factor produced by the liver. It requires vitamin K for its production. Along with other clotting factors and blood cells, it promotes blood clotting at the site of an injury.
What are the 4 steps of coagulation?
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
What is Factor 8 called?
Factor VIII (FVIII) is an essential blood-clotting protein, also known as anti-hemophilic factor (AHF). In humans, factor VIII is encoded by the F8 gene. Defects in this gene result in hemophilia A, a recessive X-linked coagulation disorder.
What is factor 8 blood disorder?
Hemophilia is a disease that prevents blood from clotting properly. A clot helps stop bleeding after a cut or injury. In factor VIII deficiency (hemophilia A), the body doesn’t make enough factor VIII (factor 8), one of the substances the body needs to form a clot.
What is Factor 5 in the blood?
Factor V Leiden (FAK-tur five LIDE-n) is a mutation of one of the clotting factors in the blood. This mutation can increase your chance of developing abnormal blood clots, most commonly in your legs or lungs. Most people with factor V Leiden never develop abnormal clots.
What is another word for coagulation?
In this page you can discover 33 synonyms, antonyms, idiomatic expressions, and related words for coagulation, like: clotting, jellification, thickening, caseation, curdling, congealing, congelation, condensation, concretion, gelling and agglomeration.
What are the steps of blood clotting process?
“e basic steps of the blood clotting process are vasoconstriction, platelet activation, thrombus formation, and dissolution of the clot. Basic laboratory tests used to identify blood clotting problems will also be presented. Blood clotting is initiated in one of two ways.
What is the half life of clotting factors?
Clotting factor has a relatively short half-life (the time it takes for a person’s clotting factor levels to drop to 50 percent, which can range from eight to 36 hours). The shorter the half-life, the more often patients will need to administer the factor.
What are the factors of clotting?
Many factors influence the ability of blood to flow through the veins and whether or not your blood will clot. Some of the contributing factors of blood clotting include cigarette smoking, advanced age, obesity, major surgery, sickle cell anemia, use of estrogen supplements,…
How many clotting factors?
Clotting factors, or coagulation factors, are a series of proteins present in the blood and which play essential parts in the clotting process. There are 13 in all, and they are traditionally numbered using Roman numerals from I to XIII.
