About Thyroid evaluation
A thyroid evaluation interprets TSH, free T4, and — when indicated — free T3, thyroid antibodies (TPO, thyroglobulin), and thyroid ultrasound. The clinical pattern guides interpretation: elevated TSH with low free T4 indicates overt hypothyroidism; suppressed TSH with elevated free T4 or T3 indicates hyperthyroidism; subclinical patterns may or may not need treatment. Levothyroxine is the standard treatment for hypothyroidism; hyperthyroidism treatment depends on cause and may include antithyroid drugs, radioactive iodine, or surgery.
