Spectrum of thyroid function in children among the patients attending to examine thyroidal illness at CNMU, Dhaka - A retrospective Study

Establishment of a standard range of thyroid hormones for Bangladesh younger population is very essential. Trials were conducted to standardize the normal range of thyroid hormones i.e. T3, T4 and TSH level, at 95% confidence limit (2sd) of age ranging from 1 day to 12 yrs of Bangladesh children group, which were differ by sex. The ranges of different thyroid status were evaluated in the In vitro Laboratory of Centre for Nuclear Medicine and Ultrasound, Dhaka. Comparing three stages (Table 2,3, and 4) observed hormone ranges at euthyroid stage marked off for overlapping the higher level of hypo thyroidal stage by lower side and the lower level of hyper thyroidal stage by higher side. Present work calculated the mean values of thyroid hormones of both sexes, which were found not affected by the sex. (author)
