[Reference values of sodium, potassium, calcium, chloride and inorganic phosphate excretion in 24-hour urine of healthy children]

Abstract

Excretion of sodium, potassium, calcium, chloride and inorganic phosphate was determined in 24 h urine of 157 healthy children (ages 6-14 years). The diet was not controlled. The statistical age- and sexspecific investigation of the results (mval/24 h, mval/24 h/mg creatinine) showed significant differences.
