Urine catecholaminesAutopsyNoradrenaline, adrenaline and dopamine levels were measured using high-performance liquid chromatography (HPLC) and electrochemical detection and related to urine creatinine in 30 specimens from unselected autopsies. Values calculated from patients with essential hypertension were used ...
C: glucagon and clonidine test in phaeochromocytoma. Methods: Patients with suspected phaeochromocytoma with moderately elevated catecholamines and/or metanephrines in plasma or urine were subjected to the ... PH Bisschop,EPM Corssmit,SJ Baas,... - 《Netherlands Journal of Medicine》 被引量:...
The new diagnostic test for dystonia We checked catecholamines and serotonin metabolites in plasma and urine of 12 dystonia patients main group by means of chromatography method and compared the results obtained from these two groups by means of the decision tree method, ... V Belenky,O Leontie...
A suggestion has been made that free metanephrines in early-morning spot urine may be the best test in the future from the perspective of both the patient and the laboratory [33]. With this in mind, ranges for free metanephrine concentrations in adult spot urines have been determined in ...
Urine from individuals with SB (n = 20) and without SB (n = 20) was subjected to liquid chromatography. The catecholamine data were compared by Mann-Whitney's test (p doi:10.1007/s11325-008-0193-7Paula SeraidarianPaulo Isaías Seraidarian...
urinary catecholaminesBackground: Measurements of urinary fractionated metadrenalines provide a useful screening test to diagnose phaeochromocytoma. Stability of these compounds and their parent catecholamines during and after urine collection is crucial to ensure accuracy of the measurements. Stabilisation ...
Background: The measurement of catecholamines and metanephrines in urine is an important diagnostic test in biochemical screening for phaeochromocytoma. Tandem mass spectrometry (MSMS) has the potential to be used in a profiling method for simultaneous assay of these analytes. Methods: Optimal ...
Stress markers (epinephrine, norepinephrine, cortisol) were collected via 12-hr urine samples and elevated concentrations were categorized using sex-specific cut-offs. Bone mineral density (BMD) was assessed via dual energy x-ray absorptiometry. Analysis of covariance models with least squares means ...
This method is 17 to 350 times more sensitive than electrochemical detection, depending on the test compounds. It has been applied to the analysis of catecholamines in urine. The sample was extracted by a metal-loaded silica prior to separation....
After stress, median percentage of increase in urine norepinephrine levels was greater in children born small for gestational age with masked hypertension than that of children born small for gestational age without masked hypertension (9.2 vs. -13.2 渭g/g creatinine, P = 0.05). There was no ...
