Urine epinephrine

Adrenaline is secreted by the adrenal medullary chromaffin cells and secretes norepinephrine and dopamine (epinephrine is part of the catecholamine). Adrenaline has the effects of sympathetic nerves exciting the cardiovascular system, promoting energy metabolism, and raising blood sugar. If the tumor is located in the adrenal medulla, the norepinephrine can be converted to adrenaline due to N-methyltransferase in the adrenal medulla. If the urinary adrenaline accounts for more than 20% of the total amount of catecholamine, the tumor is mostly located in the adrenal gland. Within the medulla, and how much the adrenal gland is related to tumor size, onset time, etc. Basic Information Specialist classification: growth and development check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Tips: Try to use fresh morning urine when doing this check. The urine that is randomly selected is preferably mid-stage urine. Menstrual women are not suitable for this examination. Normal value Urine 1 to 4 years old 0 ~ 33nmol / 24h; 5 to 10 years old 0 to 55 nmol / 24h; 11 to 15 years old 2.7 ~ 109nmol / 24h; Adult 0 ~ 82nmol / 24h. Clinical significance In the diagnosis of pheochromocytoma, catecholamines are often elevated, while elevated catecholamines in patients with pheochromocytoma are mainly norepinephrine (catecholamines include dopamine, adrenaline, norepinephrine, etc.). If the tumor is located in the adrenal medulla, the norepinephrine can be converted to adrenaline due to N-methyltransferase in the adrenal medulla. If the urinary adrenaline accounts for more than 20% of the total amount of catecholamine, the tumor is mostly located in the adrenal gland. Within the medulla, and how much the adrenal gland is related to tumor size, onset time, etc. High results may be diseases: Xiayi-Dreig syndrome considerations Note during inspection: Fresh morning urine should be used as much as possible during this examination. The urine that is randomly selected is preferably mid-stage urine. Not suitable for the crowd: menstrual women.
