This Thyroid Function Risk test measures the blood level of Thyroid Stimulating Hormone (TSH) to evaluate thyroid function, which plays an important role in regulating weight, energy, body temperature, mood, and overall health.

If TSH levels are too high or too low, this may indicate that your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism). In either case, Free Thyroxine (T4) blood levels will be evaluated at no additional cost to help accurately diagnose a thyroid disorder (including hyperthyroidism and hypothyroidism).

An undiagnosed thyroid disorder may put patients at risk for cardiovascular diseases, osteoporosis, infertility, and other serious conditions but most thyroid conditions can be managed with medication.

This test does not require fasting.
