Chronic Fatigue and Immune Dysfunction Syndrome - Chronic Fatigue Syndrome

How is the condition diagnosed?

The most important part of the diagnosis of CFS is to rule out other causes for fatigue. There are many medical illnesses that can cause fatigue. These include infections, hormone imbalances, immune system diseases, and even cancer. To rule out other conditions, a medical history and physical exam are performed. Multiple blood tests and a urine test are then done. Further tests, such as X-ray tests, may be ordered.

There is no one test that can make a diagnosis of CFS. The diagnosis of CFS is generally made when no other cause can be found for a person's fatigue and other symptoms.
