METHOD OF VERIFYING DIAGNOSIS OF PHEOCHROMOCYTOMA AND/OR PARAGANGLIOMA IN PATIENTS WITH EARLIER DETECTED LEVEL OF DAILY CONJUGATED METANEPHRINE AND/OR CONJUGATED NORMETANEPHRINE EXCRETION, EXCEEDING UPPER NORM LIMIT

摘要

FIELD: medicine. ^ SUBSTANCE: in patients with earlier detected excess of upper norm limit of level of daily conjugated metanephrine and/or conjugated normetanephrine excretion level of daily excretion of conjugated metanephrine and/or conjugated normetanephrine is determined in sample of collected urine at the background of clonidine intake. Sample is positive if the level of daily excretion of conjugated normetanephrine and/or conjugated metanephrine in sample of collected urine is higher than upper norm limit. Claimed method of diagnosis verification possesses high sensitivity and specificity. ^ EFFECT: method application makes it possible to avoid carrying out unjustified surgery in patients with essential arterial hypertension and hormonally non-active formation of adrenal gland.
