TSH enhancement of FT4 to FT3 conversion is age dependent [PDF]

European Journal of Endocrinology, 2016
ObjectiveWe previously reported increasing free T3 (FT3) to free T4 (FT4) ratios as thyroid-stimulating hormone (TSH) increases within the normal range in children. It is not known if this phenomenon is age-related among humans, as previously reported in rats.

CDC Clinical Standardization Programs (CSP) for Free Thyroxine (FT4) to Improve the Accuracy and Reliability of FT4 Measurements in Patient Care and Clinical Research [PDF]

Journal of the Endocrine Society, 2021
Abstract Reliable FT4 measurement is critical to assess thyroid function and diagnose and treat thyroid disorders. The Partnership for the Accurate Testing of Hormones (PATH) categorizes FT4 as a biomarker in high need for standardization, and currently high inter-assay variability restricts the interpretation of FT4 results in patient ...

The T4/T3 quotient as a risk factor for differentiated thyroid cancer: a case control study

Journal of Otolaryngology - Head and Neck Surgery, 2017
Background The incidence of thyroid nodules is increasing among patients in North America. Few of these nodules harbour malignancy, thus further research is required to identify predictive markers of malignant thyroid disease.
