    Leukocyte count; White blood cell count
    Definition
    This is a blood test to measure the number of white blood cells (WBCs). It is almost always part of the CBC (complete blood count). See also blood differential.
    How the test is performed
    Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to fill with blood.
    A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
    For an infant or young child:
    The area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.
    How to prepare for the test
    No special preparation is necessary for adults.
    For infants and children:
    The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For specific information regarding how you can prepare your child, see the following topics:
    How the test will feel
    When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
    Why the test is performed
    To measure the number of white blood cells in the blood. White blood cells are the major infection-fighting cells in the body. They are also involved in reactions to allergies, tumors, and stress in general.
    Normal Values
    4,500-10,000 white blood cells/mcl (cells per microliter)

    What abnormal results mean
    Low numbers of WBCs (leukopenia) may indicate:
    • bone marrow failure (for example, due to infection, tumor, fibrosis)
    • presence of cytotoxic substance
    • collagen-vascular diseases (such as lupus erythematosus)
    • disease of the liver or spleen
    • radiation
    High numbers of WBCs (leukocytosis) may indicate:
    • infectious diseases
    • inflammatory disease (such as rheumatoid arthritis or allergy)
    • leukemia
    • severe emotional or physical stress
    • tissue damage (for example, burns)
    • anemia
    This test may be performed under many conditions and in many disease states.
    What the risks are
    Risks associated with having blood drawn are slight:
    • excessive bleeding
    • fainting or feeling light-headed
    • hematoma (blood accumulating under the skin)
    • infection (a slight risk any time the skin is broken)
    • multiple punctures to locate veins
    Special considerations
    There are several types of white blood cells (WBCs) that normally appear in the blood: neutrophils (polymorphonuclear leukocytes; PMNs), band cells (slightly immature neutrophils), T-type lymphocytes (T cells), B-type lymphocytes (B cells), monocytes, eosinophils, and basophils.
    Any infection or sudden stress will result in an increased production of WBCs. This usually means increased numbers of cells and an increase in the percentage of immature cells (mainly band cells) in the blood. This change is called a "shift to the left."
    Interfering factors:
    • Acute emotional or physical stress can increase WBC counts.
    • People who have had their spleen removed (splenectomy) will have a persistent mild elevation of WBCs.
    • Drugs that may increase WBC counts include epinephrine, allopurinol, aspirin, chloroform, heparin, quinine, corticosteroids, and triamterene.
    • Drugs that may decrease WBC counts include antibiotics, anticonvulsants, antihistamine, antithyroid drugs, arsenicals, barbiturates, chemotherapeutic agents, diuretics, and sulfonamides.
    • Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others

    Erythrocyte count; Red blood cell count
    Definition
    This is a blood test that measures the number of red blood cells (RBCs). The RBC count is almost always part of the CBC (complete blood count) test.
    RBCs transport hemoglobin. Hemoglobin transports oxygen. The amount of oxygen body tissues receive depends on the amount and function of RBCs and hemoglobin. RBCs normally survive about 120 days in the blood. They are then removed by specialized "clean-up" cells in the spleen and liver.
    How the test is performed
    Blood is drawn from a vein, usually on the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to fill with blood.
    A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
    For an infant or young child:
    The area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.
    How to prepare for the test
    No special preparation is necessary for adults.
    For infants and children:
    The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For specific information regarding how you can prepare your child, see the following topics:
    How the test will feel
    When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
    Why the test is performed
    This test can help identify anemia (low hemoglobin) as well as other conditions affecting the red blood cells.
    Normal Values
    RBC (varies with altitude):
    • male: 4.7 to 6.1 million cells/mcl
    • female: 4.2 to 5.4 million cells/mcl
    Note: cells/mcl = cells per microliter
    What abnormal results mean
    Abnormal RBCs have a shorter-than-normal life span. Trauma within the blood vessels, such as that caused by artificial heart valves or peripheral vascular (blood vessel) disease, can damage RBCs. An enlarged spleen, as can be caused by portal hypertension or leukemia, may remove normal red cells along with aging ones.
    Higher-than-normal numbers of RBCs may indicate:
    Lower-than-normal numbers of RBCs may indicate:
    nutritional deficiencies of:
    Additional conditions under which the test may be performed:
    What the risks are
    • excessive bleeding
    • fainting or feeling light-headed
    • hematoma (blood accumulating under the skin)
    • infection (a slight risk any time the skin is broken)
    • multiple punctures to locate veins
    Special considerations
    • The RBC count may be decreased during pregnancy because of an increase in body fluids.
    • The RBC will increase over a period of several weeks after moving to a higher altitude.
    • Dehydration increases the RBC count.
    • Drugs that can increase the RBC count include gentamicin and methyldopa. Drugs that can decrease the RBC count include chloramphenicol, hydantoins, and quinidine.
    • Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others
