Thyroid stimulating hormone.
If TSH is suppressed: Free T4 (thyroxine free).
If TSH is high or high normal, and there is a strong clinical suspicion of hyperthyroidism (ie, pituitary origin): Free T4 (thyroxine free).
If Free T4 (thyroxine free) is normal and there is a strong clinical suspicion of hyperthyroidism: Free T3 (triiodothyronine free).
See also Hyperthyroxinaemia
Radioactive isotope uptake studies (nuclear medicine).
Monitoring: TSH should be within the reference interval although this may take 2-3 months to achieve; Free T4 may be useful in the early stages of treatment.
Patients with a history of thyroid disease should always have TSH performed prior to anaesthesia/surgery.
