trimester. Free T4 indices were almost normal during pregnancy and 2.4 times higher in mole. Free T4 levels, measured with dialysis and RIA, were slightly low during pregnancy but remarkably high in mole. Basal TSH levels were within normal range for these subjects. Beta-HCG levels in mole ...
SUMMARYA 16-year-old boy with chronic lymphocytic thyroiditis was noted to have a low free thyroxine (T4) level, low triiodothyronine resin uptake (T3U), and high serum thyrotropin (TSH) values. Unexpectedly, markedly elevated T3 radioimmunoassay (RIA) and T4 (RIA) values, using a double ant...
Perhaps the most striking observation of our study is the striatal T3 deficiency observed in the THRSP OE mice despite normal levels of circulating TSH, T4, and T3, indicating brain-specific T3 deficiency without hypothyroxinemia (low TH levels in the blood) in this transgenic animal model. It...
The total as well as free T3 levels were consistently high (out of range) whereas the T4 (total and free) values were always within normal limits. The thyrotropin was found to be partially suppressed. Very low T3-Uptake indicated some kind of interference in the immunoassays. We incubated ...
total T3, iodine uptake and cholesterol of the study group were similar to controls but significantly (P < 0.001) lower than in hyperthyroid patients, except for cholesterol which was higher. In contrast, the basal TSH, increase in TSH after TRH stimulation, and decrease of T4 during T3 ...
TSH secretion as well as 123I-uptake was suppressed only partially by T3 (75 μg/day for a week). Close examination of thyroid functions and TRβ gene analysis were not possible in the family, except for paternal grandmother and one of her two sisters who showed no abnormality. The ...
Therefore, if thyrotoxicosis is clinically suspect, and T4 and FTI are normal, the test "T3 -RIA" is recommended (this is not the same test as "T3 uptake," which has nothing to do with the amount of T3 in the patient's serum). T4 is decreased in hypothyroidism and in euthyroid ...
Thyroid Stimulating Hormone (TSH) Pituitary production of TSH is measured by a method referred to as IRMA (immunoradiometric assay). Normally, low levels (less than 5 units) of TSH are sufficient to keep the normal thyroid gland functioning properly. When the thyroid gland becomes inefficient, ...
