Overview
Various parameters like fractional sodium excretion, urinary sodium concentration, urine osmolality and U/P creatinine ratio have been used to diagnose acute renal failure. The fractional sodium excretion is identifies as the most effective non-invasive test in formulating the differential diagnosis of acute renal failure.
Differentiating Acute renal failure from other Diseases
- FENa more than 1:
- Acute tubular necrosis
- Non-oliguric acute tubular necrosis
- Acute urinary tract obstruction
- FENa less than 1:
- Acute glomerulonephritis
- Pre-renal azotemia
