Urinary free catecholamines determined by liquid chromatography--fluorometry.
نویسندگان
چکیده
Free norepinephrine, epinephrine, and dopamine are determined in urine after purification on a small ion-exchange column and concentration on alumina. The catecholamines are separated by reversed-phase ion-pair chromatography and are quantitated by measuring their native fluorescence (lambda ex 285 nm, lambda em 305 nm). The internal standard is dihydroxybenzylamine. Within-day CVs for the compounds ranged from 1.6 to 5.6%; between-day CVs were 6.6 to 9.8%.

Analysis of total urinary catecholamines by liquid chromatography: methodology, routine experience and clinical interpretations of results.
A simple routine method is described for simultaneous assay of total urinary adrenaline, noradrenaline and dopamine. The catecholamines are pre-purified on a small ion-exchange column, separated by reversed phase ion-pair liquid chromatography, and are quantitated by electrochemical detection. The method was routinely applied to 422 urines. Elevated values were found in four urine specimens obt...
متن کاملEvaluation of urinary metanephrine and normetanephrine enzyme immunoassay (ELISA) kits by comparison with isotope dilution mass spectrometry.
Determination of urinary 3-O-methylated catecholamines (metanephrines) is generally considered a principal test for the clinical chemical diagnosis of pheochromocytoma and is currently performed predominantly with chromatographic techniques such as gas-liquid chromatography and HPLC. Enzyme immunoassays based on microtiter plate technology have recently been developed for the quantitative deter...
متن کاملDifferential assay for urinary catecholamines by use of liquid chromatography with fluorescence detection.
I describe a relatively simple and rapid procedure for quantitative analysis for unconjugated urinary norepinephrine, epinephrine, and dopamine. Catecholamines are isolated from urine on a carboxylic acid ion-exchange resin (Bio-Rex 70) and eluted with 0.8 mol/L boric acid. The eluates are assayed for the individual catecholamines by "high-performance" liquid chromatography with an octadecylsil...
متن کاملPaediatric reference values for urinary catecholamine metabolites evaluated by high performance liquid chromatography and electrochemical detection.
The majority of the published reference range data on catecholamines excretion by healthy children is incomplete and often contradictory (1). We assayed in the urines of 127 healthy children the values of the catecholamines (norepinephrine, epinephrine, dopamine) and their methylated metabolites (normetanephrine, metanephrine, 3-methoxytyramine) for the determination of paediatric reference ran...
متن کاملFreedom from drug interference in new immunoassays for urinary catecholamines and metanephrines.
BACKGROUND Determination of urinary free catecholamine and total (i. e., free plus conjugated) metanephrine excretion is considered the most clinically sensitive biochemical test for pheochromocytoma. In this study, we evaluated new immunoassay methods for the measurement of these analytes for potential drug-based interference. METHODS Urine samples collected from patients on a variety of med...
