what the risks are blood test, total iron binding capacity, blood test that measures the total iron binding capacity, tibc, an indirect measure of transferrin, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the band to fill, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, an infant, young child, area is cleansed, antiseptic, punctured, a sharp needle, a lancet, blood collected, pipette, small glass tube, on a slide, onto a test strip, into a small container, cotton, a bandage applied, puncture site, any continued bleeding, fast, 8 hours, infants, children, test depends on child's age, level of trust, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the needle is inserted to draw blood, feel moderate pain, others feel only a prick, stinging sensation, some throbbing, this test, performed, iron deficiency is suspected, a cause of anemia, 65%, the iron, in the body, carried in hemoglobin, red blood cells, 4% in myoglobin, in skeletal muscle, 30%, the iron, in the body is stored, a substance, ferritin, in the liver, bone marrow, spleen, a small percentage, the body's iron is in transport, molecule, transferrin, traveling between various parts, the body via the blood stream, a serum iron test actually measures the amount, iron in transferrin, each transferrin molecule, carry 2 iron atoms, 30%, the available "spaces", iron, filled, by artificially filling up all the available spaces, measure the total iron binding capacity, tibc, blood, tibc, higher-than-normal, the body's iron stores, iron, 60-170 mcg/dl, tibc, 240-450 mcg/dl, transferrin saturation, 20-50%, mcg/dl = micrograms per deciliter higher-than-normal tibc, iron deficiency anemia, pregnancy, lower-than-normal tibc, cirrhosis, hemolytic anemia, hypoproteinemia, pernicious anemia, sickle cell anemia, inflammation, malnutrition, liver disease, additional conditions under which the test performed, anemia of chronic disease, risks associated, having blood drawn, slight, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, drugs, increase tibc measurements include fluorides, oral contraceptives, drugs, decrease tibc measurements include acth, chloramphenicol, veins, arteries vary in size, obtaining a blood sample.
