When should a thyroid test be performed?
When you have signs of a thyroid issue, such as fatigue, weight gain, or depression, you should have your thyroid checked. If thyroid issues run in your family, you should also get a thyroid test.
Every year to check for changes in your thyroid hormone levels, your doctor may likely request a thyroid function test from you. If you have an autoimmune illness or are taking medications that can impact the thyroid gland, he or she could also recommend more frequent testing.
