The aim of this research was to investigate whether serum thyroxin concentration, within the normal reference intervals were age-related among children and adolescents. This investigation was carried out on 243 subjects who were chosen randomly from all those patients who were referred during the one-year period from to the Danesh Medical Diagnostic Laboratory in Gorgan, northern Iran.
The thyroxin concentrations of the subjects were obtained from the outpatient records of the patients who were referred to the Laboratory during 2007-08. The thyroxin concentrations were determined by the Radio Immunoassay method by using standard laboratory kits. The sample population were divided into 4 age groups of 1-5 years, 6-10 years, 11-15 years and 16-21years. The results of this study showed that there is an inverse age correlation between thyroxin concentrations among children and adolescents in this region.
