  1. Factor VII assay Factor VII assay
    The factor VII assay is a blood test to measure the activity of factor VII -- one of the substances needed for blood clotting (coagulation). How the Test is Performed Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The area is cleaned with germ-ki...
  2. Factor VII deficiency Factor VII deficiency
    Factor VII deficiency is an inherited disorder in which a lack (deficiency) of plasma protein factor VII leads to abnormal bleeding. Causes This disorder occurs when the body does not have enough factor VII, an important blood clotting protein. When you bleed, the body launches a series of reaction...
  3. Factor VIII assay Factor VIII assay
    The factor VIII assay is a blood test that measures the activity of factor VIII -- one of the substances involved in blood clotting (coagulation). How the Test is Performed Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The area is cleaned with g...
  4. Factor X assay Factor X assay
    The factor X assay is a blood test to measure the activity of factor X -- one of the substances involved in blood clotting (coagulation). How the Test is Performed Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The area is cleaned with germ-killi...
  5. Factor X deficiency Factor X deficiency
    Factor X deficiency is a disorder caused by too little of a protein called factor X in the blood. It leads to problems with blood clotting (coagulation). Causes When you bleed, the body launches a series of reactions that help the blood clot. This is called the coagulation cascade. The process invo...
  6. Factor XII (Hageman factor) deficiency Factor XII (Hageman factor) deficiency
    Factor XII deficiency is an inherited disorder that affects a protein (factor XII) involved in blood clotting. Causes When you bleed, the body launches a series of reactions that help the blood clot. This is called the coagulation cascade. The process involves special proteins called coagulation fa...
  7. Factor XII assay Factor XII assay
    The factor XII assay is a blood test to measure the activity of factor XII -- one of the substances involved in blood clotting. How the Test is Performed Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The area is cleaned with germ-killing medicin...
  8. Failure to thrive Failure to thrive
    Failure to thrive is a description applied to children whose current weight or rate of weight gain is significantly below that of other children of similar age and sex. Causes Infants or children that fail to thrive seem to be dramatically smaller or shorter than other children the same age. Teenag...
  9. Fainting Fainting
    Fainting is a temporary loss of consciousness due to a drop in blood flow to the brain. The episode is brief (lasting less than a couple of minutes) and is followed by rapid and complete recovery. You may feel light-headed or dizzy before fainting. A longer, deeper state of unconsciousness is often ...
  10. Familial combined hyperlipidemia Familial combined hyperlipidemia
    Familial combined hyperlipidemia is a disorder of high cholesterol and high blood triglycerides that is inherited, which means it is passed down through families. Causes Familial combined hyperlipidemia is the most common genetic disorder of increased blood fats that causes early heart attacks. How...
  11. Familial dysbetalipoproteinemia Familial dysbetalipoproteinemia
    Familial dysbetalipoproteinemia is a disorder passed down through families in which there are high amounts of cholesterol and triglycerides in the blood. Causes A genetic defect causes this condition. The defect results in the buildup of large lipoprotein particles that contain both cholesterol and...
  12. Familial hypercholesterolemia Familial hypercholesterolemia
    Familial hypercholesterolemia is a disorder of high LDL ("bad") cholesterol that is passed down through families, which means it is inherited. The condition begins at birth and can cause heart attacks at an early age. See also: Familial combined hyperlipidemia Familial hypertriglyceridemia Fam...
  13. Familial hypertriglyceridemia Familial hypertriglyceridemia
    Familial hypertriglyceridemia is a common disorder passed down through families in which the level of triglycerides (a type of fat) in a person's blood are higher than normal. The condition is not associated with a significant increase in cholesterol levels. Causes Familial hypertriglyceridemia is ...
  14. Familial lipoprotein lipase deficiency Familial lipoprotein lipase deficiency
    Familial lipoprotein lipase deficiency is a group of rare genetic disorders in which a person lacks a protein needed to break down fat molecules. The disorder causes large amounts of fat to build up in the blood. Causes Familial lipoprotein lipase deficiency is usually caused by a defective gene th...
  15. Familial Mediterranean fever Familial Mediterranean fever
    Familial Mediterranean fever is a disorder passed down through families (inherited), which involves repeated fevers and inflammation that often affects the abdomen or lungs. Causes Familial Mediterranean fever is caused by a mutation in the MEFV gene. The condition usually affects people of Mediter...
