what the risks are kidney, blood, urine flow, plasma renin activity, random plasma renin, pra, renin test measures the amount, renin, in the blood, adult, child, 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, 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, a bandage applied, puncture site, any bleeding, health care provider, advise to withhold drugs, affect the test, "special considerations", consume a normal, balanced diet, low-sodium content, 3 gm/day, 3 days, 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, plasma renin activity, pra, measured, the diagnosis, treatment of hypertension, patients, primary hyperaldosteronism, have an increased aldosterone, more information see the aldosterone test, production associated, a decreased pra, patients, secondary hyperaldosteronism, kidney disease, renal vascular disease, have increased plasma levels of renin, aldosterone, patients, have renin, aldosterone levels checked in essential hypertension to evaluate, patients, salt-sensitive, cause a low renin, normal aldosterone levels, helps to guide the physician in choosing the correct medication, patients, salt-sensitive patients, low renin hypertension respond well to diuretic medications, renin, enzyme released by specialized cells, the kidney, blood, in response to sodium depletion, low blood volume, renin converts angiotensinogen, a protein released, blood by the liver, to angiotensin i, angiotensin i is converted to angiotensin ii, enzyme, in the veins, the lungs, angiotensin ii acts on the adrenal cortex to stimulate the release of aldosterone, aldosterone acts on the distal tubules, the kidneys to decrease the loss of sodium ions, secondarily fluid, has the effect of increasing blood pressure, angiotensin causes, constriction of small blood vessels, increases blood pressure, normal values range from 1.9 to 3.7 ng/ml/hour, normal value ranges, among different laboratories, ng/ml/hour = nanograms per milliliter per hour, abnormal results, greater-than-normal levels, addison's disease, cirrhosis, essential hypertension, hemorrhage, bleeding, hypokalemia, malignant hypertension, renin-producing renal tumors, renovascular hypertension, lower-than-normal levels, salt-retaining steroid therapy, adh therapy, salt-sensitive essential hypertension, primary hyperaldosteronism, excessive bleeding, fainting, feeling lightheaded, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, renin measurements, pregnancy, salt intake, time of day, a standing vs, prone position, drugs, affect renin measurements include antihypertensives, diuretics, estrogens, oral contraceptives, vasodilators, veins, arteries vary in size, obtaining a blood sample.
