Renal Clearance and Fractional Excretion of Electrolytes and Inorganic Phosphate in Healthy Male Infants

Abstract

Reference values for urinary excretion of electrolytes in infants are rather rare. The authors succeeded in obtaining accurate collection of urine in a group of 30 healthy boys aged 2 - 12 months.

The following parameters were assessed in serum and urine samples: Na, K, Cl, Ca, phosphate, creatinine. Reference values for clearance and fractional excretion of these parameters were obtained.

Statistically significant correlations between age (2 - 12 months) and clearance and fractional excretion of the studied parameters were not proved.
