what the risks are blood test, norepinephrine, blood, epinephrine, blood, adrenalin, blood, dopamine, blood, blood test, catecholamines measures the level of catecholamines, in the plasma portion of blood, catecholamines, more often measured, a urine test than, blood test, 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, certain foods, increase catecholamine levels, coffee, tea, bananas, chocolate, cocoa, citrus fruits, vanilla, avoid these foods, several days, serum, urine catecholamines, to be measured, avoid other interfering factors, acute stress, vigorous exercise, consult health care provider regarding the need to discontinue potentially interfering drugs, drugs, increase catecholamine measurements include caffeine, levodopa, lithium, aminophylline, chloral hydrate, clonidine, disulfiram, erythromycin, insulin, methenamine, methyldopa, nicotinic acid, large doses, quinidine, tetracyclines, nitroglycerin, drugs, decrease catecholamine measurements include clonidine, disulfiram, guanethidine, imipramine, mao inhibitors, phenothiazines, salicylates, reserpine, never discontinue any medication, first consulting provider, 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 is used primarily to screen, diagnose, monitor treatment of pheochromocytoma, neuroblastoma, catecholamines, chemically similar small molecules derived from tyrosine, an amino acid, major catecholamines, dopamine, norepinephrine, epinephrine, adrenalin, dopamine, neurotransmitter, a chemical, transmit impulses between nerve cells, mainly found, in the brain, norepinephrine, primary neurotransmitter, in the sympathetic nervous system, controls "fight, flight" reactions, found, in the brain, epinephrine is not only a brain neurotransmitter but also a major hormone, epinephrine is secreted, adrenal medulla in response to low blood glucose, exercise, various forms of acute stress, epinephrine causes, several responses, a breakdown of glycogen to glucose, in the liver, release of fatty acids from fat tissue, vasodilation of small arteries, muscle tissue, increase in rate, strength, the heartbeat, normal value ranges, among different laboratories, epinephrine, 20 ng/100 ml, ng/ml = nanograms per milliliter, norepinephrine, 60 ng/100 ml, elevated levels of blood catecholamines, indicate the following, acute anxiety, ganglioblastoma, ganglioneuroma, neuroblastoma, rare, pheochromocytoma, rare, severe stress, shy-drager syndrome, 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, test's accuracy, several foods, drugs, such things, physical activity, stress, veins, arteries vary in size, obtaining a blood sample, more difficult, than from others.
