Additional Information
Noticeable changes in your metabolism (e.g., weight, temperature, and energy) may be an indication of abnormal levels of thyroid stimulating hormone (TSH) in your blood. This thyroid function test measures the TSH levels in your blood to help identify these abnormalities. High TSH levels may indicate an overactive thyroid (i.e., hyperthyroidism), while low TSH levels may suggest an underactive thyroid (i.e., hypothyroidism). In either case, T4 reflex testing will be performed at no additional cost to help identify a possible thyroid disorder. Thyroid disorders can affect any system of your body and treatment will depend on the specific thyroid condition. An undiagnosed thyroid disorder may put you at risk for cardiovascular diseases, osteoporosis, infertility, and other serious conditions; most thyroid conditions can be managed with medication.
