| factor ix assay | A test used to measure the activity of a blood clotting factor IX (Christmas factor). This test may be used to evaluate excessive bleeding. Abnormally low factor IX assays may be seen in the following conditions: congenital deficiency of factor IX, fat malabsorption, heparin administration, cirrhosis, vitamin K deficiency and warfarin administration. (27 Sep 1997) |
|---|---|
| factor ix deficiency | A form of haemophilia in males that results from a deficiency of clotting factor IX, transmitted as a X-linked trait. Symptoms include easy bruising, nosebleeds, bleeding gums and bleeding into muscle tissue (haematoma) or a joint space (haemarthrosis). Treatment includes the infusion of factor IX concentrates to normalize blood coagulation. (27 Sep 1997) |
| factor ixa | <enzyme> Activated form of factor ix. This activation can take place via the intrinsic pathway by the action of factor xia and calcium, or via the extrinsic pathway by the action of factor viia, thromboplastin, and calcium. Factor ixa serves to activate factor x to xa by cleaving the arginyl-leucine peptide bond in factor x. Registry number: EC 3.4.21.22 (12 Dec 1998) |
| factor P | A chemical (postulated by T. Lewis), formed in ischemic skeletal or cardiac muscle, held to be responsible for the pain of intermittent claudication and angina pectoris. (05 Mar 2000) |
| factor v | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| factor v assay | A test used to measure the activity of a blood clotting factor V. This test may be used to evaluate excessive bleeding. Abnormally low factor V assays may be seen in the following conditions: congenital deficiency of factor V, DIC, heparin administration, cirrhosis and primary fibrinolysis. (27 Sep 1997) |
| factor v deficiency | An inherited disorder that results in abnormal blood clotting due to the deficiency of factor V, one of 20 plasma proteins responsible for the maintenance of normal blood clotting. Symptoms include excessive bleeding, bleeding gums, nosebleeds, easy bruising, excessive menstrual bleeding and bleeding into muscle tissue (haematoma) or a joint space (haemarthrosis). Treatment includes the infusion of fresh frozen plasma to restore deficient factor V. (27 Sep 1997) |
| factor V1a | The hexa-amide of cobyrinic acid; a part of the vitamin B12 structure. Synonym: cobyrinamide, cobyrinic hexa-amide, factor V1a. (05 Mar 2000) |
| factor va | <chemical> Activated form of factor v. It is an essential cofactor for the activation of prothrombin catalyzed by factor xa. Chemical name: Blood-coagulation factor Va (12 Dec 1998) |
| factor vii | <chemical> Heat- and storage-stable plasma protein that is activated by tissue thromboplastin to form factor viia in the extrinsic pathway of blood coagulation. The activated form then catalyses the activation of factor x to factor xa. Chemical name: Blood-coagulation factor VII (12 Dec 1998) |
| factor vii assay | A test used to measure the activity of a blood clotting factor VII. This test may be used to evaluate excessive bleeding. Abnormally low factor VII assays may be seen in the following conditions: congenital deficiency of factor VII, fat malabsorption, heparin administration, cirrhosis, vitamin K deficiency and warfarin administration. (27 Sep 1997) |
| factor vii deficiency | An inherited disorder that causes abnormal blood clotting due to the congenital absence of one of the 20 different plasma proteins involved in the coagulation process. Symptoms include bleeding of the gums, nosebleeds, easy bruising, bleeding in muscles or joints and excessive menstrual bleeding. Treatment includes the administration of plasma concentrates of factor VII (extrinsic factor). (27 Sep 1997) |
| factor viia | <enzyme> Activated form of factor vii. Factor viia activates factor x in the extrinsic pathway of blood coagulation. Registry number: EC 3.4.21.21 (12 Dec 1998) |
| factor viii | A coagulation (clotting) factor. Classic haemophilia (haemophilia A) is due to a congenital deficiency in the amount (or activity) of factor VIII. Factor VIII is also known as antihemophiliac factor (AHF) or antihemophiliac globulin (AHG). The gene for factor VIII (that for classic haemophilia) is on the X chromosome so females can be silent carriers without symptoms and males can be haemophiliacs. (12 Dec 1998) |
| factor viii assay | A test used to measure the activity of a blood clotting factor VIII (Von Willebrand factor). This test is usually used to monitor treatment of haemophilia. Abnormally low factor VIII assays may be seen in the following conditions: congenital deficiency of factor VIII (haemophilia), DIC and secondary fibrinolysis. This test may also be performed in the evaluation of Von Willebrand's disease. (27 Sep 1997) |
