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.

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

Thyroid physiology and thyroid function testing
Otolaryngologic Clinics of North America, 2003The art and science of medicine has changed so much in the last 40 years, not only in the manner that physicians treat medical diseases but also in how they diagnose them. Technological advances have made it possible to have a test for almost anything.

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 ...

BIOCHEMICAL TESTING OF THYROID FUNCTION
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.

COMPARATIVE TESTS OF THYROID FUNCTION
Annals of Internal Medicine, 1952Excerpt In this report are included comparative studies on approximately 45 patients whose thyroid function was appraised by four laboratory tests, in addition to routine clinical observations.

The commonly used thyroid function tests can be divided into three categories: blood tests that assess the functional status of the thyroid gland (T4, T3R, T3RIA, TSH), tests that dynamically evaluate the pituitary—thyroid axis (TRH test, cytomal suppression test), and in vivo isotopic tests (radioiodine uptake tests, thyroid scan, etc.).

Publisher Summary This chapter presents the tests and functions of thyroid. Nearly all the circulating, organically bound iodine is normally incorporated in thyroxine (T 4 ). More than 99% of this T 4 is bound to a specific thyroxine-binding globulin (TBG); this bound T 4 is physiologically inactive.

Thyroid Function Tests in Thyroid and Nonthyroid Disease
CRC Critical Reviews in Clinical Laboratory Sciences, 1983Modern day evaluation of thyroid disorders requires a combination of accurate clinical judgement and reliable, sensitive, and specific thyroid functions tests. Principle among the latter are thyroxine (T4) 3, 5, 3'-triiodothyronine (T3), and thyroid-stimulating hormone (TSH).

Thyroid disorders are common. At least 5% of the adult population in Western countries have hypothyroidism, hyperthyroidism, goitre or a nodule in the thyroid. Most of those with a goitre or nodule are euthyroid, but laboratory confirmation of this is required.
