Hyperthyroidism is a condition where your thyroid gland produces too much of the hormones triiodothyronine (T3) and thyroxine (T4). It can induce an array of symptoms, such as fatigue, weight loss, and an irregular heart rhythm. If left untreated, it can potentially lead to serious health consequences, so it is important to look out for signs and symptoms, and then run the tests necessary to diagnose it.

Blood Tests
The most common test is a blood test, which measures your T3 and T4 levels. It is often also used to check for thyroid-stimulating immunoglobulin (TSI), which is responsible for triggering thyroid overactivity. This test is important in determining if you have hyperthyroidism.
Imaging Tests
Imaging tests help doctors examine the structure of the thyroid gland and detect any abnormalities that may be causing the hyperthyroidism. An ultrasound is the most common imaging test used to diagnose hyperthyroidism. It uses high-frequency sound waves to create detailed images of the thyroid that can detect nodules and other potential abnormalities. Most nodules are benign, but some can cause excessive levels of T4 and T3.
Thyroid Scan
A thyroid scan is another imaging test that can help diagnose hyperthyroidism. It uses small amounts of radioactive iodine to create detailed images of the thyroid. This helps physicians detect any problems with the size and shape of the gland.
Thyroid Peroxidase Antibody Test
A thyroid peroxidase antibody test helps diagnose the autoimmune form of hyperthyroidism, called Grave’s Disease. This test checks for higher-than-normal levels of antibodies which can trigger the overactivity of the thyroid.
Other Diagnostic Tools
Your doctor may also use other diagnostic tools to diagnose hyperthyroidism. These include physical exams and a detailed medical history to look for any other symptoms and determine what could be causing them. They may also request thyroid function tests, which measure the levels of thyroid hormones in the blood.
Conclusion
Hyperthyroidism is a condition with serious health consequences if left untreated, so it is important to be aware of the signs and symptoms, and to talk to your doctor if you think you may have it. Your doctor can use a combination of tests and imaging tools to diagnose it and, if needed, recommend a treatment plan.
