How is hypothyroidism diagnosed?

Hypothyroidism is typically diagnosed through blood tests that evaluate thyroid hormone levels. The most common screening test measures thyroid-stimulating hormone (TSH).

At Vital Living Healthcare, physicians may also evaluate additional markers such as Free T4 and Free T3, which provide more insight into how much thyroid hormone is circulating and available for use by the body. Diagnosis also includes evaluating symptoms, medical history, and overall hormone balance.
