Diagnosis involves several aspects:
- Medical history: The doctor will ask the patient about the symptoms and how long the patient has had them.
- Clinical examination: The doctor will check for any medical signs (e.g. swollen lymph nodes, inflamed joints, etc.).
- Laboratory tests: The doctor may test the patient's blood for inflammation markers and/or autoantibodies.
Additionally, the doctor's knowledge and awareness, and effective communication between doctor and patient, are essential to the process of making an accurate diagnosis.
