Thyroid Gland
Investigations to check function
what we check for
Free thyroxine
Free T3
TSH : thyroid stimulating hormone
How should an elevated TSH level be investigated?
If TSH is high, check TSH with free T4 (FT4)
Thyroid ultrasonography and thyroid scintigraphy should not be performed for uncomplicated hypothyroidism without a palpable nodule.
How should a suppressed TSH level be investigated?
if TSH is low, check FT4 and FT3
positive TSH receptor antibodies (TRAb; or thyroid stimulating immunoglobulins [TSI]) support a diagnosis of Graves’ disease
thyroid ultrasonography is generally unhelpful in determining the cause of hyperthyroidism
