A. A dysfunction of the thyroid gland can be safely excluded when the local finding of the thyroid gland, perhaps including an ultrasound, is normal and the TSH-levels are unchanged (between 0.4 and 4.0 microE/ml). B. A hyperthyreosis can be proven in 98% when TSH is suppressed (possibly a negative TSH-test) and the T3 levels and the FT3 levels, respectively, are elevated. Following examinations are necessary for the further diagnostics: When a Base-dow hyperthyreosis is suspected, T4, TR and TPO antibodies should be measured and an ultrasound obtained. When a focal or disseminated autonomy is suspected, a scintigraphy and suppression scintigraphy, respectively as well as an ultrasound should be undertaken. C. A hypothyreosis can be proven in 98% when TSH is elevated (possibly an overshooting TSH test), and the T4 levels are low. For further diagnostics, ultrasound and maybe scintigraphy should be undertaken in case of a congenital hypothyreosis. In case of an acquired hypothyreosis, TR and TPO antibodies should be measured, an ultrasound obtained, and a cytology might be taken to exclude a thyreoiditis De Quervain or a Hashimoto thyreoiditis.

UI MeSH Term Description Entries
D006980 Hyperthyroidism Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE. Hyperthyroid,Primary Hyperthyroidism,Hyperthyroidism, Primary,Hyperthyroids
D007037 Hypothyroidism A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.

D003937 Diagnosis, Differential Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures. Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis
D006042 Goiter Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC). Goiters
