Thyroid Panel
What preparation is needed for this Checkup?
No test preparation is needed. However, certain medications, multivitamins and supplements can interfere with thyroid testing, so tell your healthcare practitioner about any prescribed or over-the-counter drugs and/or supplements that you are taking. If you take thyroid hormone as treatment for thyroid disease, it is recommended that your blood sample be drawn before you take your dose for that day. Acute illness may affect thyroid hormone test results. It is generally recommended that thyroid testing be avoided in hospitalized patients or postponed until after you have recovered from the illness.

When you have signs and symptoms suggesting underactive thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism) due to a condition affecting the thyroid; when you have an enlarged thyroid (goiter) or a thyroid nodule (a small lump on the thyroid gland that may be solid or a fluid-filled cyst)
