WebPlasma concentrations of free metanephrines are relatively independent of renal function and are, therefore, more suitable for diagnosis of pheochromocytoma among patients with renal failure than measurements of deconjugated metanephrines. Plasma metanephrines in renal failure Kidney Int. WebPlasma free metanephrines (PFM) are the most specific parameters for the diagnosis of extraadrenal chromaffin tumors. The measurement of PFMs (metanephrine (M), normetanephrine (NM) and 3-methoxytyramine (MT)) is challenging because of their polar nature, their low molecular weight and their low physiological concentration in human … eds fish truck
