TīmeklisThe FENa is a measure of the extraction of sodium and water from the glomerular filtrate. It is the ratio of the sodium filtration rate to the overall glomerular filtration rate …

The FeNa Test : Use in the Differential Diagnosis of Acute Renal

Tīmeklis2024. gada 16. marts · Previously, it was believed that urine sodium excretion and fractional excretion of sodium (FENa) could help differentiate between “prerenal” and “intrinsic renal” failure. However, more recent evidence shows that FENa performs poorly. ( 27236480, 26689284, 27670788) http://www.nephjc.com/news/sglt2mechanism circe in spanish https://cantinelle.com
