Fractional absorbance

WebFractional excretion of bicarbonate: Fractional excretion of bicarbonate is a marker of proximal tubular handling of bicarbonate. The proximal tubule normally reabsorbs almost all filtered bicarbonate (fractional excretion below 5%). A value greater than 15% indicates proximal RTA while levels are in the normal range in distal RTA. The WebTrue bioavailability, or fractional absorption, refers to the amount that is absorbed with oral administration compared to the amount found by intravenous administration, which …
