Diagnosis is made through the patient’s symptoms as well as medical history and blood tests. Your doctor will prescribe blood test to find abnormal levels of hormones. One test is the TSH, thyroid-stimulating hormone, which is very sensitive for detecting hypothyroidism. If it is elevated, hypothyroidism means since the gland to produce more T4. The other is the test of T4, which is attached to a thyroxine-binding globulin (protein).
You can also perform another test with radioactive iodine, and if the iodine uptake is low, is also a sign of hypothyroidism.
