    Factor II assay

    The factor II assay is a test to measure the activity of factor II — one of the substances involved in blood clotting (coagulation).

  • Disease

    Factor II deficiency

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    Factor II deficiency is a blood clotting (coagulation) problem that occurs when there is a lack of a substance (prothrombin) that is needed for blood to clot.

  • Test

    Factor IX assay

    The factor IX assay is a blood test that measures the activity of factor IX — one of the substances involved in blood clotting (coagulation).

  • Test

    Factor V assay

    The factor V assay is a blood test to measure the activity of factor V — one of the substances involved in blood clotting (coagulation).

  • Disease

    Factor V deficiency

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    Factor V deficiency is a condition that is passed down through families, which affects the ability of the blood to clot.

  • Test

    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).

  • Disease

    Factor VII deficiency

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    Factor VII deficiency is an inherited disorder in which a lack (deficiency) of plasma protein factor VII leads to abnormal bleeding.

  • Test

    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).

  • Test

    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).

  • Disease

    Factor X deficiency

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    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).

  • Disease

    Factor XII (Hageman factor) deficiency

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    Factor XII deficiency is an inherited disorder that affects a protein (factor XII) involved in blood clotting.

  • Test

    Factor XII assay

    The factor XII assay is a blood test to measure the activity of — one of the substances involved in blood clotting.

  • Disease

    Fanconi syndrome

    The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

    Fanconi syndrome is a disorder of the kidney tubes in which certain substances normally absorbed into the bloodstream by the kidneys are released into the urine instead.

    Fanconi's anemia

    Blood transports oxygen and nutrients to body tissues and returns waste and carbon dioxide. Blood distributes nearly everything that is carried from one area in the body to another place within the body. For example, blood transports hormones from endocrine organs to their target organs and tissues. Blood helps maintain body temperature and normal pH levels in body tissues. The protective functions of blood include clot formation and the prevention of infection.

    Fanconi’s anemia is a disease passed down through families (inherited) that mainly affects the bone marrow. It results in decreased production of all types of blood cells. Fanconi’s anemia is different from , a rare kidney disorder.

  • Test

    Ferritin blood test

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    The ferritin blood test measures the level of ferritin in the blood. Ferritin is a protein found inside cells that stores iron so your body can use it later. A ferritin test indirectly measures the amount of iron in your blood.

  • Test

    Fibrin degradation products

    Fibrin degradation products (FDPs) are the substances left behind when clots dissolve in the blood. This article discusses the blood test to measure these products.

  • Test

    Fibrinogen

    Fibrinogen is a protein produced by the liver. This protein helps stop bleeding by helping blood clots to form. A blood test can be done to tell how much fibrinogen you have in the blood.

  • Disease

    Fibrinolysis - primary or secondary

    Blood clots (fibrin clots) are the clumps that result when blood coagulates.

    Fibrinolysis is a normal body process that keeps naturally occurring from growing and causing problems. Primary fibrinolysis refers to the normal breakdown of clots. Secondary fibrinolysis is the breakdown of blood clots due to a medical disorder, medicine, or other cause. This may cause severe ...

    Folate deficiency

    The first trimester of pregnancy is the first three months after conception. Signs of early pregnancy are missed menstrual periods, fatigue, breast enlargement, abdominal distention, and nausea. During this period of time all organ development takes place so the fetus is most susceptible to damage from toxins, drugs, and infections.

    Folate deficiency means you have a lower than normal amount of , a type of B vitamin, in your blood.

  • Disease

    Folate-deficiency anemia

    This picture shows large, dense, oversized, red blood cells (RBCs) that are seen in megaloblastic anemia. Megaloblastic anemia can occur when there is a deficiency of vitamin B-12.

    anemia is a decrease in red blood cells () due to a lack of folate. Folate is a type of B vitamin. It is also called folic acid. Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues.

    Folic acid - test

    Folic acid is a type of B vitamin. This article discusses the test to measure the amount of folic acid in the blood.
