Abstract：
OBJECTIVES:To determine pediatric reference values for serum zinc concentration in Iranian subjects. DESIGN AND METHODS:Serum zinc concentration was measured by flame atomic absorption spectrometry in 699 children and adolescents. Reference values for serum zinc were determined according to the Clinical and Laboratory Standards Institute/International Federation of Clinical Chemistry guidelines. Dietary zinc intake was assessed using a validated semiquantitative food frequency questionnaire. RESULTS:Overall 95% reference values for serum zinc concentrations were 9.7-31.5, 9.2-30.9, and 9.3-31.1 μmol/L in boys, girls, and total population respectively. Serum zinc concentrations were comparable in boys and girls (17.5 ± 5.3 μmol/L vs. 17.2 ± 5.6 μmol/L, p=0.242). The dietary zinc intake of 7.6% (4.9% boys and 10.2% girls, p<0.01) was lower than the estimated average requirement. CONCLUSIONS:This study presents pediatric reference values for serum zinc concentrations, values that could help diagnose and manage zinc deficiency in pediatrics.
