A thyroid hormone test evaluates whether your thyroid is producing enough hormones to maintain normal function. The thyroid gland dictates your body's metabolism and body growth.
Note any symptoms that are associated with thyroid disorders. For example, many patients with hypothyroidism experience fatigue and weight gain. Hyperthyroidism causes weight loss, rapid heartbeat and anxiety.
Speak to your doctor about ordering a thyroid hormone test. Many doctors check a person's thyroid levels as a part of their yearly physical. Thyroid hormone tests are typically ordered alongside a blood test that measures a person's TSH. TSH is the thyroid stimulating hormone found in the body and it can also indicate a possible thyroid condition.
Allow blood to be drawn. A thyroid hormone test is performed by taking blood from the patient and checking the T4 and T3 levels in the blood sample.
Wait for the results. Thyroid hormone test results usually come back within a couple of days. Your doctor will receive a copy and discuss your options based on the numbers. If the hormone levels come back in an abnormal range, the doctor probably will prescribe a medication to improve the levels. You will repeat the blood test after you start on the medicine.
