    The relationship between serum tri-iodothyronine (T3) and thyroxine-binding globulin (TBG) has been studied in euthyroid subjects. This relationship is similar to that previously described for thyroxine (T4) and TBG. Serum T3, TBG and T4 data are presented for euthyroid subjects of all ages and the T4:T3 and T3:TBG ratios calculated. Similar data has been derived for patients with clinically proven thyrotoxicosis and for patients in which the diagnosis was in doubt. The results suggest the T3:TBG ratio enhances the use of the T3 assay to confirm thyrotoxicosis. The fact that 25% of our patients suffering from thyrotoxicosis had apparently normal serum T4 levels reinforces the contention that a serum TBG assay must be carried out as part of a basic thyroid function screen.

    Pulmonary Tuberculosis IV

    Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
    Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
