Serum TSH and free T4 levels were determined usingmicroparticle enzyme immunoassay (MEIA). Maternal age ranged from18 to 47 years, mean of 32.5 ± 6.9 years. Mean gestational age was19.1 ± 8.5 weeks. With linear regression analysis, the 50th and 97.5thpercentiles for TSH and the 2.5th, ...
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 were greatly in excess of peak concentrations that were seen at 9-13 weeks of normal pregnancy...
Rapid reversal of subclinical hyperthyroidism in patients with large multinodular goitres after thyroidectomy. A patient is said to have subclinical hyperthyroidism if he has a depressed thyroid stimulating hormone (TSH) level but is clinically euthyroid and has a normal thyroxine (T4) and ...

higher thyroid stimulating hormone (TSH) and lower free thyroxine (free T4) levels across the spectrumof hypo- to hyperthyroidism[21]. However, it is still uncertain whether NAFLD associates with variations in thyroid function within the euthyroid range. Clinical Biochemistry 47 (2014) 1028–1032 ...

Relationships of thyroid stimulating hormone (TSH) and free thyroxine (free T4) with leptin, adiponectin and the L/A ratio in euthyroid subjects were documented in 67 fasting subjects with metabolic syndrome (Mets) and 86 euthyroid subjects without MetS (TSH and free T4levels within the ...
Conclusions Women with unexplained infertility and high‐normal TSH levels treated with levothyroxine had a higher rate of conception but lower live birth rate compared to untreated women, with the limitation of a small sample size. These findings assert the need for prospective, randomized studies ...
