The main test for hyperthyroidism is to check three thyroid functions, and the cost of this test is about$150. When hyperthyroidism is suspected, blood tests, liver function and electrocardiogram can be done together with the thyroid function test, and these results can provide some reference for the treatment plan of hyperthyroidism. The total cost of thyroid function, blood test, liver function and ECG together is about 250-300 RMB. When a patient with hyperthyroidism is seen for the first time, the physician will need a cardiac ultrasound if he/she finds or considers hyperthyroidism in combination with heart problems.
