Determining Thyroid Disorders in Younger Age Group (pre-Pubertal, Peri-Pubertal & Pubertal) Individuals: An Observational Study

Objective: Determine thyroid disorders in younger age group (pre-Pubertal, Peri- Pubertal & Pubertal) individuals. Method: : Blood samples were obtained from patients advised assessment of thyroid hormone levels, during an eight month period spanning from May to December 2010. Only those subjects were included for this study, which had been evaluated for all three parameters of thyroid function (T3, T4, and TSH). The assessment of free frac- tion of T3 and T4 was carried out keeping in view their diagnostic advantage over the total hormones. Serum thyroid hormones from patients’ serum were estimated by using the Roche Elecsys 2010 immunoassay analyzer installed at the Reproductive Physiology department of the National Institute of` Health, Islamabad. It is an auto- mated analyzer with inbuilt software system, and is based on electrochemiluminis- cence. Data of all subjects were expressed as Mean±SD, and compared statistically by correlation, and student’s “t” test. Result: Serum samples of 12 pre-pubertal (6-9 years) subjects were evaluated for their thyroid functions. Results of 8 subjects showed normal thyroid hormone levels, and 3 different patterns of abnormal activity were observed. In peri-pubertal subjects (10- 15 years) Serum of 28 (19 female and 9 male) subjects in this age group (10-15 years) were evaluated for thyroid function, and 19 subjects showed normal results constitut- ing 14 female and 5 males. In pubertal subjects serum samples of 37 individuals of this age group (16-19 years) were evaluated for thyroid function. Out of which 25 individ- uals showed normal thyroid activity, and FT4 and TSH had significant (p
