Conclusion: Higher fT4 levels within the reference range were associated with an increased prevalence and incidence of AF. These findings in a large dataset prospectively validate earlier reports and may have important implications, including a redefinition of the normal range and fT4 targets for ...
thyroxine levels were elevated within 3 and 9 hours after ingestion, with values slowly declining into the normal range over the course of 6 and 36 days, respectively. The initial serum thyroxine concentration in this case was 4900.9 nmol/L (normal range of 5.3 to 26.7 nmol/L).10Most ...
below the normal range for age throughout the study period but was significantly higher in those children who had normal TSH levels.There was a wide range of L-thyroxine dosage at all age groups and it was those with the lower doses per kg body weight who had the raised TSH levels. The...
As with total T4levels, these interpretations may be modified in the light of further test results. With some free-T4methods, the upper part of the euthyroid range becomes extended with the age of the patient, so that ingeriatricpatients, results below 30 pmol/L may be considered normal. ...
The contention that the Liquisol assay provides "excellent clinical correlation," providing their normal reference ranges are used, overlooks a critical clinical situation. Using either the reference range we determined in our own control subjects or using the reference range given with the Liquisol ...
Some patients had subclinical thyroid disorders, which means that only TSH levels are dysregulated, while fT4 levels remained within normal range. Around 15 patients had subclinical hyperthyroidism (75% of 20 hyperthyroid pa- tients), and 14 patients had subclinical hypothyroidism (34% of 41 ...
[1]. Therefore, maternal thyroid dysfunction might result in subsequent adverse consequences. For example, compared with the normal-range levels, maternal higher free thyroxine (FT4) levels in early pregnancy have been associated with lower birth weight and an increased risk of small gestational age...
"normal" range for serum T4. The desired parameters may be attained with different batches of the monoclonal antibodies merely by variation of the proportion. By use of the antibody combination, the assay may be configured to operate in the range of maximum accuracy of radioimmunoassay design and...

Salivary T4 levels were higher than predicted, 4.2-35 ng/dl (normal range 0.6-2.0). No correlation was found between salivary T4 and serum levels of free T4 and total T4 but there was a significant correlation between salivary T4 and albumin (r = 0.82). Salivary cortisol levels agreed ...
