The usual diagnosis of hyperthyroidism is determined by an elevated thyroxine (T4) level. Less commonly, isolated increased triiodothyronine (T3) levels are found, especially in nodular thyroid disease. Rarely has hyperthyroidism been diagnosed with normal (or low) T4 and T3 levels.
甲状腺功能亢进的常见诊断是根据甲状腺素（T4）水平升高来确定的。较少见的情况是，发现三碘甲状腺原氨酸（T3）水平单独升高，尤其是在结节性甲状腺疾病中。甲状腺功能亢进极少在T4和T3水平正常（或偏低）的情况下被诊断出来。
