Thyroid function tests are usually used to fully reflect the functional indicators of the thyroid gland, and the cost of thyroid function tests cannot be generalized. The average price is around 300 to 400 yuan, but if the city level and the hospital level are high, the cost may be higher. The five thyroid tests are an important part of the medical checkup because some diseases are difficult to detect because of their early symptoms. The five thyroid tests usually include serum total T3 measurement, serum total
T4, serum free T4, serum free T4, and thyroid stimulating hormone TSH. A high value indicates hyperthyroidism or primary biliary cirrhosis, while a low value indicates hypothyroidism or iodine-deficient goiter. If the results of the five thyroid tests are unsatisfactory, further tests are usually needed, and if B-form ultrasound is added, the total cost is about $500 to $600. Therefore, the cost of the five thyroid tests varies from region to region and from hospital to hospital, and if B-form ultrasound is added, the cost will be around 400 to 800 RMB.
