FREE THYROXINE (FT4) AND FREE TRIIODOTHYRONINE (FT3) IN AUTONOMOUS THYROID NODULES

Clinical Endocrinology, 1979
SUMMARYTotal and free thyroid hormones (T3, T4, FT3 and FT4), TSH and its response to TRH were determined in sixty‐three patients affected by autonomous thyroid nodules: mean concentrations of free T3 (FT3) were significantly higher in hot nodules (suppressing extranodular tissue on the scan) as compared to warm ones, even in those cases where total T3

Value of the free triiodothyronine index in the diagnosis of hyperthyroidism

European Journal of Nuclear Medicine, 1980
Normalized T4 (T4N), total T3, T3 resin sponge uptake (T3U) and the response of TSH to TRH were determined in 264 patients sent for diagnosis of thyroid function. Many of these patients were diagnostic problem cases. Those with disease or medication known to invalidate the TRH test, but not those with abnormal thyroid hormone binding capacity in serum,

TOTAL AND FREE THYROXINE AND TRIIODOTHYRONINE IN NORMAL AND COMPLICATED PREGNANCY

Obstetrical & Gynecological Survey, 1976
Serum concentrations of total and free thyroxine (T4 and FT4) and total and free triiodothyronine (T3 and FT3) were measured in normal pregnant women, in patients with toxemia of pregnancy, and in patients with gestational trophoblastic disease (GTD). In normal pregnancy, FT4 and FT3 levels remained normal while T4 and T3 levels were elevated.

Levothyroxine therapy and serum free thyroxine and free triiodothyronine concentrations

Journal of Endocrinological Investigation, 2002
Although the normal thyroid gland secretes both levothyroxine (L-T4) and levotriiodothyronine (L-T3), normalization of serum TSH with L-T4-replacement therapy alone in hypothyroidism is generally believed to result in a normal serum L-T3 and to reflect a euthyroid state. However several recent studies suggest that this may not be the case. Accordingly,

Serum free triiodothyronine in obesity.

International journal of obesity, 1983
Serum concentrations of free triiodothyronine (T3) and total T3 were measured in 25 grossly obese patients with constant body weight and no dietary restrictions. The results were compared with serum free T3 and total T3 in 55 non-obese volunteers matched in sex and age.

Reevaluation of Thyroid Function in Low Birth Weight Infants Based on Free Triiodothyronine and Triiodothyronine

Biology of the Neonate, 2009
We attempted to analyze the physiological meaning of abnormally low thyroid hormones in low birth weight (LBW) infants on the basis of cross-sectional data on free triiodothyronine (free T₃) and T₃ in addition to the other thyroid hormones.

Amerlex free triiodothyronine and free thyroxine levels in normal pregnancy

BJOG: An International Journal of Obstetrics & Gynaecology, 1985
Summary. Free triiodothyronine (FT3) and free thyroxine (FT4) were measured in 159 women during normal pregnancy and compared with non‐pregnancy reference ranges for these hormones. FT3 values fell from the reference level of 6·34 (SD 1·06) pmol/l to 3·87 (SD 0·54) pmol/l in the 3rd trimester; corresponding figures for FT4 were: reference 16·92 (SD 2 ...

Simultaneous Measurement of Free Thyroxine and Free 3,5,3′-Triiodothyronine in Undiluted Serum by Direct Equilibrium Dialysis/Radioimmunoassay: Evidence that Free Triiodothyronine and Free Thyroxine are Normal in Many Patients with the Low Triiodothyronine Syndrome

Thyroid, 1998
We have devised a practical, sensitive and specific method for simultaneous measurement of free thyroxine (FT4) and free triiodothyronine (FT3) in undiluted serum by direct equilibrium dialysis radioimmunoassay (RIA). Two hundred microliters serum sample was dialyzed against buffer (pH 7.4) for 20 hours at 37 degrees C and approximately 800 microL of ...
