Summary
Establishing accurate thyroid reference ranges is crucial for clinical diagnosis. This study determined specific reference values for free thyroxine (FT4), free triiodothyronine (FT3), and thyrotropin (TSH) in an adult population, addressing analyser discrepancies.
Area of Science:
- Clinical chemistry
- Endocrinology
- Laboratory medicine
Context:
- Observed discordances in thyroid reference ranges using the BCF Access 2 analyser.
- Need for population-specific reference values for accurate thyroid function testing.
- Established inclusion/exclusion criteria for a healthy adult cohort.
Purpose:
- To establish specific reference range values for free thyroxine (FT4), free triiodothyronine (FT3), and thyrotropin (TSH).
- To address discrepancies noted with the BCF Access 2 analyser in a clinical laboratory setting.
- To improve the clinical utility of thyroid biomarkers.
Summary:
- Studied 308 adults (18-65 years) excluding pregnant women and those with iodine contrast media use.
- Excluded patients with thyroidal, cardiac, renal, or multiple-organ-failure illnesses.
- Measured thyroid assays, anti-TPO, and anti-TG levels using the BCF Access 2 immunoassay system.
Impact:
- Highlights challenges in defining reliable reference ranges for thyroid hormones.
- Aims to provide a more accurate biomarker interpretation in the clinical context.
- Facilitates improved diagnosis and management of thyroid disorders.

01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

01:18Functions of Thyroid Hormones
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:23Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
