WebThe fractional excretion of HCO 3 − ions is used to examine net H + ion secretion in PCT. In this test, NaHCO 3 is given to raise the P HCO 3 to the normal range so that one can measure the rate of excretion of HCO 3 − ions and compare it with the filtered load of HCO 3 − ions (see Eqn 6; margin note).If more than 15% of filtered HCO 3 − ions is excreted, … trickle creek golf kimberley bcWebA fractional excretion of uric acid (FEUA) ... bicarbonate administration, Addison’s Disease, isolated acquired hypoaldosteronism, or cerebral/renal salt wasting.
