Although distinct, the classical biochemical signature – hyperthyroxinaemia with non-suppressed TSH – is not specific to thyrotropinoma, as drug effects, non-thyroidal illness, and assay interference can all yield similar patterns of thyroid function tests. Even when these more common confounders have been exclude...
