Overview
This section provides a short and straight to the point overview of the disease or symptom. The first sentence of the overview must contain the name of the disease.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
Common Causes
Diagnosis
Serum TSH measurement has the highest sensitivity and specificity of any single blood test used in the evaluation of suspected thyrotoxicosis and should be used as an ini-tial screening test . However, when thyrotoxicosis is strongly suspected, diagnostic accuracy improves when aserum TSH, free T4, and total T3 are assessed at the initial evaluation. Serum TSH levels are considerably more sensitive than direct thyroid hormone measurements for assessing thyroid hormone excess. In overt hyperthyroidism, serum free T4,T3,or both are elevated, and serum TSH is subnormal (usually<0.01mU/L ina third-generation assay). In mild hyperthyroidism, serum T4 and free T4 can be normal, only serum T3 may be elevated, and serum TSH will be low or undetectable
