Diagnosis
The most effective and efficient way to diagnose hypothyroidism is by measuring the thyroid stimulating hormone (TSH) level in your blood, which will be high if you have the disease. At the same time, the thyroid hormones, T4 and T3, will be low.
Other tests may be performed to determine the cause of hypothyroidism, including measuring thyroid antibody levels.
