    Aim and methods: To understand the utility of paired FT4 and TSH test in determining functional status of Thyroid in diagnostic and follow up settings, we studied 34159 test results. We divided the population into all 9 nine possible classes by using the reference values of the FT4 and TSH. Then we determined class frequency, reference ranges of FT4 and TSH for each class, their Mean Differences (MD) between classes and pattern of association between them within a class. Results: Euthyroid population has FT4 and TSH (14.83–14.90 pmol/ml) and (2.40–2.43 µIU/ml) respectively as 95% Confidence Interval and there is no association between them (r=-0.056; sig. 0.000). Major bulk of abnormal thyroid function (98.15%) is constituted by 4 classes namely Primary Hypothyroid, Primary Hyperthyroid, Compensated Hypo.. Read More»
