Unless your doctor asks you to fast for your thyroid test(s), usually you do not need to for a blood test. Some thyroid tests, such as a thyroid uptake scan, requires you to stay away from eating certain fish (usually shellfish) prior to and shortly after the test is conducted. Talk with your doctor if you have any questions regarding how they want you to prepare for your thyroid tests.
