Urine catecholamines in paediatrics.
INTRODUCTION In paediatric clinical practice, tests for urinary catecholamines and their metabolites are most often requested to aid in the diagnosis and follow-up of patients with neural crest tumours, particularly neuroblastomas. Neuroblastoma is the most common extracranial solid tumour in children. Each year 80–90 new patients are diagnosed in the UK, most of them infants or toddlers. Neuro...
متن کاملThe estimation of catecholamines in urine by a chemical method.
The estimation of urinary catecholamines has assumed clinical significance mainly because of its value in the diagnosis of phaeochromocytoma (Engel and Euler, 1950; Euler, 1951). Since biological methods have obvious limitations for routine work, various chemical methods have been developed (Lund, 1950; Pekkarinen and Pitkanen, 1955; Euler and Floding, 1955a, b). They are based on the same prin...

متن کاملAutomated microdetermination of inorganic phosphorus in serum and urine by the ammonium molybdovanadate method.
Continuous flow assay of inorganic phosphorus in 20 ¡A serum or urine is described. The procedure is based on the formation of a colored complex of inorganic phosphorus with ammonium molybdovanadate and does not require the presence of a reducing agent, thus producing an extremely stable baseline. The reaction product is measured at 340 nm for serum samples but at 420 nm for urine samples, sinc...
