Controversies in Thyroid Function Testing
Clinics in Laboratory Medicine, 1984Thyroid function tests can be abnormal in certain patients in the absence of thyroid dysfunction. All thyroid function tests can be affected in these patients, including the free thyroxine assays and free thyroxine index. Familiarity with the conditions affecting thyroid function tests is necessary to avoid incorrect diagnosis and unnecessary testing.

Endocrinology and Metabolism Clinics of North America, 1997Various published guidelines recommending serum thyrotropin (TSH)-first thyroid testing are outlined. The entities called "subclinical hypothyroidism" and "subclinical hyperthyroidism" are defined on the basis of abnormal TSH concentrations and normal values of other biochemical thyroid tests.

In vitro tests of thyroid function
Seminars in Nuclear Medicine, 1971The principal in vitro tests of thyroid function currently available have been described and assessed as to their clinical usefulness. Three groups have been considered: those which measure thyroid hormone concentration (PBI, BEI, T 4 by column, T 4 and T 3 by competitive protein binding), those which measure the extent of thyroid hormone-plasma ...

THYROID-FUNCTION TESTS IN THE ELDERLY
The Lancet, 1972Abstract Serum protein-bound iodine (P.B.I.) and triiodothyronine (T 3 ) uptake measurements were performed as the initial tests of thyroid function on 490 patients admitted to a geriatric department. Up to 20 % of the euthyroid patients had reduced thyroxine-binding-globulin (T.B.G.) levels. Interpretation of these tests is difficult since P.B.I. and

Abnormal thyroid function tests in children on ethionamide treatment.
The International Journal of Tuberculosis and Lung Disease, 2011Ethionamide (ETH) treatment may cause hypothyroidism. Clinical data, serum thyroid stimulating hormone (TSH) and free thyroxine (fT4) levels were retrospectively assessed in 137 children receiving anti-tuberculosis treatment including ETH.
