title: [The TRH test in latent thyroid pathology].
abstract: TRH-test is an usefull tool for diagnostic purpose in thyroid disease. We challenged with TRH 4 groups of patients (1 degrees non toxic diffuse goitre, 2 degrees nodular goitre (Plummer's disease), 3 degrees euthyroid ophthalmic Graves' disease, 4 degrees hemithyroidectomy) with different thyroid affections who showed no symptoms and presented normal values of total thyroid hormones, in comparison with a control group. These groups displayed normal and pathological (blunted or absent and exaggerated) responses of TSH to TRH. Therefore TRH-test ra presents a good mean to recognize subclinical forms both hyperthyroidism and hypothyroidism.
