WebThe 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. WebRenal Bicarbonate Excretion. Overview. Because bicarbonate is not secreted by the tubule, the rate of renal bicarbonate excretion is ultimately determined by the balance between its rate of glomerular filtration and tubular resorption. Because the rate of glomerular filtration is maintained at a fairly constant level, specific regulation of ...
