Acute tubular necrosis is a kidney disorder involving damage to the tubule cells of the kidneys, resulting in acute kidney failure. ATN presents with AcuteRenal Failure(ARF) and is one of the most common causes of ARF. This online calculator helps you to calculate the ARF index.
Formula:
RFI = UNa x SCr/UCr
Where,
RFI = Renal Failure Index
UNa = Urine Sodium in mg/dL
SCr = Serum Creatinine in mg/dL
UCr = Urine Creatinine in mg/dL
