what the risks are blood test, low density lipoprotein, ldl, test that measures the amount, low-density lipoprotein, ldl, cholesterol in blood serum, blood is drawn, a vein, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, vein to swell, 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 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, a bandage applied, puncture site, any bleeding, fasting, 12 hours advised, advise to withhold 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, a prick, stinging sensation, some throbbing, this test, performed, part of an evaluation of coronary risk factors, cholesterol, important, normal part, the structure of our cell membranes, bile acids, steroid hormones, cholesterol, does not dissolve in water, most cholesterol, carried, in the blood by lipoproteins, large protein-like molecules, chylomicrons, very low density lipoprotein, vldl, high density lipoprotein, hdl, ldl, chylomicrons, lipoproteins, present shortly after a meal, disappear, 2 hours in "normal" people, ldl seems to be to carry cholesterol to various tissues throughout the body, laboratory actually measures the cholesterol portion, the ldl molecule, rather than the actual concentration of ldl, in the blood, true, hdl, vldl, total cholesterol level, sum of ldl, hdl, vldl cholesterol, excess cholesterol, in the blood has been correlated, cardiovascular disease, ldl is sometimes referred to, "bad" cholesterol, elevated levels of ldl correlate most, coronary heart disease, according, national heart, lung, blood institute, ldl cholesterol level, better indicator of risk, heart attack, stroke than total cholesterol, lower ldl, lower risk, heart disease, stroke, a healthy ldl level is one that falls, in the optimal, near-optimal range, optimal, less than 100 mg/dl, near optimal, 100-129 mg/dl, borderline high, 130-159 mg/dl, 160-189 mg/dl, very high, 190 mg/dl, higher, goal ldl levels, patients at high risk, atherosclerosis, patients, diabetes, known heart disease lower than 100 mg/dl, normal value ranges, among different laboratories, high levels of ldl associated, increased risk of atherosclerotic heart disease, familial hyperlipoproteinemia, lower-than-normal levels of ldl, malabsorption, inadequate absorption of nutrients, intestinal tract, malnutrition, additional conditions under which the test performed, familial combined hyperlipidemia, familial dysbetalipoproteinemia, familial hypertriglyceridemia, 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 lipoprotein levels include aspirin, oral contraceptives, phenothiazines, corticosteroids, sulfonamides, veins, arteries vary in size, obtaining a blood sample.
