A simple, regular blood test is used to guide treatment for hypothyroidism and monitor the condition. The main job of the thyroid gland is to make the hormone thyroxine, also known as T4 because it has four iodine molecules. The thyroid also makes the hormone triiodothyronine, known as T3 because it has three iodine molecules, but in smaller amounts, explains Cathy Doria-Medina, MD , an endocrinologist with HealthCare Partners Medical Group in Torrance, California.

The pituitary gland at the base of the brain controls hormone production in your body. It makes thyroid-stimulating hormone TSH , which tells the thyroid gland how much T4 and T3 to produce. The TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make. If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism.

Doria-Medina explains. A normal range for TSH in most laboratories is 0. Your doctor may also order a T4 test. A blood test can measure how much free T4 if available. Hypothyroidism is treated with daily medication.

Taking synthetic thyroid hormone medication can bring your T4 and TSH levels back to their normal ranges. When you first start taking medication, your doctor will need to monitor your blood to fine-tune the dosage. Medication for hypothyroidism is slow acting, and it can take several weeks for your body to adjust.
