    Schilling test

    The Schilling test is performed to evaluate vitamin B12 absorption. B12 helps in the formation of red blood cells, the maintenance of the central nervous system, and is important for metabolism. Normally, ingested vitamin B12 combines with intrinsic factor, which is produced by cells in the stomach. Intrinsic factor is necessary for vitamin B12 to be absorbed in the small intestine. Certain diseases, such as pernicious anemia, can result when absorption of vitamin B12 is inadequate.

    The Schilling test is used to determine whether the body absorbs normally.

    Serum free hemoglobin test

    Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen. In the lungs, oxygen is exchanged for carbon dioxide. Abnormalities of an individual's hemoglobin value can indicate defects in the normal balance between red blood cell production and destruction. Both low and high values can indicate disease states.

    Serum free hemoglobin is a blood test that measures the level of free in the liquid part of the blood (the serum). Free hemoglobin is the hemoglobin outside of the red blood cells. Most of the hemoglobin is found inside the red blood cells, not in the serum.

    Serum globulin electrophoresis

    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.

    This lab test measures the levels of proteins called globulins in the fluid (serum) part of a blood sample. Other electrophoresis tests that measure proteins in the serum include: Immunoelectrophoresis Protein electrophoresis

    Serum iron 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.

    Serum iron is a test that measures how much iron is in your blood.

  • Disease

    Sickle cell anemia

    Sickle cell anemia is an inherited blood disease in which the red blood cells produce abnormal pigment (hemoglobin). The abnormal hemoglobin causes deformity of the red blood cells into crescent or sickle-shapes, as seen in this photomicrograph.

    Sickle cell anemia is a disease passed down through families. The red blood cells that are normally shaped like a disc take on a sickle or crescent shape. Red blood cells carry oxygen throughout the body.

    The sickle cell test looks for the abnormal in the blood that causes the disease .

  • Symptoms

    Splenomegaly

    Because of its wide variety of functions, the spleen may be affected by many conditions involving the blood or lymph system, and by infection, malignancies, liver disease, and parasites.

    Splenomegaly is a larger-than-normal spleen.

    Sugar-water hemolysis test

    The sugar-water hemolysis test is a blood test to detect fragile red blood cells by testing their ability to withstand swelling in a low-salt solution.
