How is Hashimoto’s Disease diagnosed?

Hashimoto's disease is usually diagnosed through a combination of blood tests, physical examination, and sometimes imaging tests. The most common blood tests used to diagnose Hashimoto's disease include:

• Thyroid-stimulating hormone (TSH) test: This test measures the level of TSH in the blood. People with Hashimoto's disease typically have an elevated level of TSH and a low level of thyroid hormones, such as T4 and T3.
• Thyroid peroxidase (TPO) antibodies test: This test measures the level of TPO antibodies in the blood. People with Hashimoto's disease typically have elevated levels of these antibodies.
• Thyroglobulin antibodies test: This test measures the level of thyroglobulin antibodies in the blood. People with Hashimoto's disease typically have elevated levels of these antibodies.

Physical examination such as feeling the thyroid gland to see if it is enlarged, and imaging tests such as ultrasound of the thyroid can also aid in diagnosis. A doctor may also evaluate the patient's medical history, family history, and symptoms to arrive at a diagnosis.

It is important to note that Hashimoto's disease can sometimes be difficult to diagnose, as the symptoms can be like other conditions, and the blood test results may not always be definitive. If you have symptoms that suggest Hashimoto's disease, it's important to see a doctor for a proper diagnosis and treatment.
