Thyroid Function Test

Who Should Book This Test?

For most thyroid function tests, no special preparation is needed—eating and drinking normally is fine unless instructed otherwise. However, if other blood tests are being done simultaneously, fasting may be required. For a thyroid scan, avoid iodine-rich foods (e.g., seafood, dairy, iodized salt) for about a week prior to the procedure. Always follow your healthcare provider’s specific instructions to ensure accurate results.
