Data for: Detection of Spot Urinary Free Metanephrines and 3-Methoxytyramine with Internal Reference Correction for the Diagnosis of Pheochromocytomas and Paragangliomas

These clinical data were obtained based on our established HPLC-fluorescence/ultraviolet detection of normetanephrine, metanephrine, 3-methoxytyramine and creatinine in spot urine samples. All statistical analysis and diagnostic methods for pheochromocytomas and paragangliomas were analyzed based on these data.
