Thyroid Function


Additional information


This is the most helpful screening test to evaluate for thyroid disorders (underfunction or overfunction), which may affect your weight, level of energy, mood and overall health.
About 20 million Americans suffer from thyroid disease, with the majority not knowing that they have it. TSH is produced by the brain and changes depending on the thyroid hormone levels in the blood, and is the most used marker to test for this.
If it is abnormal, this test will automatically also test for the level of thyroid hormone in the blood (T4).
