We compared the free-thyroxine index in normal adults and in euthyroid patients taking diphenylhydantoin. All subjects had normal serum thyrotropin concentrations. Serum thyroxine concentrations were determined by two commonly used competitive protein-binding assays, which yielded slightly different values, but which consistently showed the same degree of decrease in mean serum thyoxine concent...

Chadd, M. A., Gray, 0. P., and Davies, D. F. (1970). Archives of Disease in Childhood, 45, 374. Thyroid function tests in the newborn. The 131I triiodothyronine (T3) resin uptake test reflects thyroid function more closely than other acceptable tests currently available. The T3 uptake and protein-bound iodine (PBI) level were estimated in 20 premature and 20 full-term infants at birth and at th...

Different thyroid function tests permitted a final classification of 204 consecutive patients with suspected thyroid disorders into three populations (thyrotoxic, euthyroid, and hypothyroid). Linear discriminant analysis was applied to all test results (10 variates) on adjacent population pairs. Two invitro tests (serum protein bound iodine (P.B.I.) and tri-iodothyronine (T-3) uptake values) ga...

Thyroid uptake tests are essentially kinetic tests which reflect the speed with which certain phases of thyroid hormone biosynthesis are taking place. Under equilibrium conditions the rate at which the thyroid accumulates iodine is closely related to the rate of production of thyroid hormone. The nature of the information provided by thyroid uptake measurements is different therefore from that ...

In 1999, 890 000 measurements of thyroid stimulating hormone were performed by Scottish hospital laboratories—approximately one test for every six of Scotland’s 5.1 million people. This number does not include tests performed in the non-NHS laboratories or as part of the screening programme for congenital hypothyroidism. Although laboratory statistics are not collected nationally in England and...

conclusions: the current review is aimed at analyzing and managing various clinical aspects of hypothyroidism in hospitalized elderly, and critically ill geriatric patients. context: articles in various international and national bibliographic indices were extensively searched with an emphasis on thyroid and hypothyroid disorders, hypothyroidism in elderly hospitalized patients, hypothyroidism ...

about 8% of the general population suffers from autoimmune diseases, from which 78% are women. one of the most important causes of thyroid diseases is autoimmunity in origin, and it seems that people with thyroid diseases present more signs of asthma. this study was therefore designed to investigate the frequency of autoimmune thyroid diseases in women suffering from bronchial asthma. in a cros...

The effect of diazepam on thyroid function tests was examined in 12 euthyroid patients requiring the drug for psychiatric reasons and in six patients with thyrotoxicosis. Assessment was made before and after four weeks' therapy.There was no significant difference in results from tests of thyroid iodide trapping and binding (thyroid radioiodine uptake, thyroid clearance, and absolute iodine upta...

MBBS, MD Department of Pathology KIST medical college, Imadole, Lalitpur, Nepal Email: [email protected] Abstract: Thyroid diseases are among the most prevalent of medical conditions. In the patients with obvious features of hypothyroidism or hyperthyroidism thyroid function tests only confirm the diagnosis. Though TSH is widely used as a screening test i...
