The fractional excretion of sodium (FE Na) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium , rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption .
Two other urinary indices, are the fractional sodium excretion (FENa) index and the renal failure index (RFI). [36] The renal failure index is equal to urine sodium times plasma creatinine divided by urine creatinine. [36] A FENa score greater than 3% or a renal failure index (RFI) greater than 3 are helpful in confirming acute renal failure. [37]
The urine sodium is expressed as a concentration (such as millimoles per liter). The result must therefore be interpreted in the context of the degree of urine concentration present. Alternatively, the urine sodium can be standardized to the excretion of creatinine using a formula such as the fractional excretion of sodium (FENa).
The renal clearance ratio or fractional excretion is a relative measure of the speed at which a constituent of urine passes through the kidneys. [ 1 ] [ 2 ] It is defined by following equation: c l e a r a n c e r a t i o o f X = C x C i n {\displaystyle clearance\ ratio\ of\ X={\frac {C_{x}}{C_{in}}}}
The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine clearance exceeds GFR due to creatinine secretion, [1] which can be blocked by ...
As a royal family fan, I'm always here for a new picture or portrait (King Charles's latest was particularly striking). Generally, they are quite posed and professional (they are royals, after all).
The largest pot of money DOGE could tap for cuts in federal programs without current congressional authorization, also called “discretionary spending,” which accounts for about $516 billion.
