Abstract
Sampling of blood in the supine position for diagnosis of pheochromocytoma and paraganglioma (PPGL) results in lower rates of false-positives for plasma normetanephrine than seated sampling. It is unclear how in-patient versus out-patient testing and other preanalytical factors impact false-positives.File in questo prodotto:
