what the risks are test that measures the amount, haptoglobin, a protein that binds free hemoglobin, in blood, 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, in 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, health care provider, advise to stop taking drugs, affect the test, "special considerations", 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, haptoglobin is measured to assess the rate at which red blood cells, destroyed, red blood cells die, a process, hemolysis, release hemoglobin, liver produces haptoglobin, secretes it, blood, where it finds, attaches to any "free" hemoglobin, hemoglobin not contained, red blood cells, concentration of free hemoglobin is ordinarily very low, the level rises whenever red blood cells, destroyed, after haptoglobin attaches to hemoglobin, molecule goes, liver where its components, iron, heme, amino acids, recycled, process destroys the haptoglobin, red blood cells, actively destroyed, rate of haptoglobin destruction by the liver, outpace the rate at which new haptoglobin is created, levels of haptoglobin, in the blood, decrease, normal range is 27-139 mg/dl, milligrams per deciliter, higher-than-normal levels, acute rheumatic disease, biliary obstruction, peptic ulcer, ulcerative colitis, inflammatory conditions, lower-than-normal levels, chronic liver disease, erythroblastosis fetalis, hematoma, hemolytic anemias, hemolytic anemia, due to g6pd deficiency, idiopathic autoimmune hemolytic anemia, immune hemolytic anemia, drug-induced immune hemolytic anemia, primary liver disease, transfusion reaction, 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, haptoglobin levels, liver disease, kidney disease, extensive blood loss, a variety of conditions that affect liver, kidney function, drugs, raise haptoglobin levels include androgens, corticosteroids, drugs, lower haptoglobin levels include birth control pills, chlorpromazine, diphenhydramine, indomethacin, isoniazid, nitrofurantoin, quinidine, streptomycin, veins, arteries vary in size, obtaining a blood sample.
