ABSTRACT
Objective To set up the reference range for thyroid hormones and thyrotropin (TSH) of 8-10 years old school children in certain regions of China to provide reference criteria for diagnosis,treatment,and monitoring of thyroid diseases and related research.Methods A cross-sectional survey was conducted in primary school children aged 8-10 years from six iodine sufficient areas.664 normal school children were selected for establishing reference ranges of thyroid hormones and TSH after crucial screening through questionnaire and laboratory investigation.The serum hormone levels were determined by using chemiluminescent immunoassay (Bayer's reagents),and the reference range of each hormone was displayed as its 95% central interval.Results The reference ranges of TSH,FT4,FT3,TT4,and TT3 were 1.03-8.42 mIU/L,13.44-20.59 pmol/L,4.75-6.96pmol/L,75.29-152.66 nmol/L,and 1.76-3.35 nmol/L,respectively.There was no significant difference in hormone levels between boys and girls.The eight years old group had slightly higher TT4 level compared with the other age groups.The rural children had higher TSH and TT3 levels and lower FT4 level than the urban children.Conclusion The thyroid hormone and TSH levels are substantially different between school children and adults.Therefore,it is necessary to establish the reference range of thyroid function indices for normal school children in order to diagnose,treat,and monitor thyroid diseases.
