By combining the results of a physical exam, lab tests, and imaging tests, your practitioner can determine if you have thyroid eye disease or something else. A Word From Verywell Talk to your healthcare provider if you have questions about the diagnosis process. Usually, you will need several tests to figure out if you have thyroid eye disease. The process may take less time if you already have a Graves' disease diagnosis. It is important to stay patient throughout the diagnosis process. You may need to see specialists, which can take time. Reach out to friends and family for support so they can help while you wait. The right diagnosis is important for receiving the correct treatment and preventing complications that may appear from Graves' disease and thyroid eye disease. You should feel comfortable asking your healthcare providers questions and getting the care you need. 4 Sources Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
