what the risks are hemoglobin, blood hemoglobin, serum hemoglobin, serum hemoglobin, test that measures the level of free, outside red blood cells, hemoglobin, in the blood, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, a tourniquet, an elastic band, blood pressure cuff, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the tourniquet to distend, fill, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, tourniquet is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, infants, young children, 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, no preparation, 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, test, detect, monitor the severity of various kinds of hemolytic anemia, breakdown of red blood cells, hemoglobin, hb, main component of red blood cells, protein that carries oxygen away, lungs, carbon dioxide back, lungs, a molecule of hemoglobin consists of 2 pairs of peptide, alpha, beta globins, chains, four heme groups, each, one atom of iron, at a normal oxygen tension of 100 mmhg, in the blood vessels, the lungs, 98%, the hb is combined, oxygen, tissues further, lungs, oxygen tension is much lower, oxygen readily separates from hb, free plasma hb separates into alpha-beta molecules, bound to a serum protein, haptoglobin, taken up by the liver, plasma hb levels exceed 50, 200 mg/dl, capacity of haptoglobin to bind hb, free alpha-beta molecules pass, urine, plasma hb that is not bound to haptoglobin nor removed by the kidneys changed to a form, methemoglobin, 11.5 to 15.5 mg/dl, vary by age, gender, testing laboratory, mg/dl = milligrams per deciliter, elevated levels, drug-induced immune hemolytic anemia, g6pd deficiency, hemoglobin c disease, hereditary spherocytosis, idiopathic autoimmune hemolytic anemia, paroxysmal cold hemoglobinuria, pch, paroxysmal nocturnal hemoglobinuria, pnh, sickle cell anemia, thalassemia, transfusion reaction, excessive bleeding, fainting, feeling lightheaded, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, veins, arteries vary in size, obtaining a blood sample.
