Use of thyroid function tests in urine: a position statement of the Belgian Thyroid Club.

The article, titled "Use of thyroid function tests in urine: a position statement of the Belgian Thyroid Club," discusses the use of urine testing for thyroid hormones and argues against its reliability and usefulness in diagnosing and managing thyroid disorders. The authors highlight limitations such as lack of sensitivity and specificity, susceptibility to interference, and lack of standardized assays and reference ranges. They emphasize that blood testing for thyroid hormones is the only evidence-based method recommended by international scientific societies for the diagnosis and management of thyroid diseases.
