Chronic Fatigue Syndrome - Diagnosis

Diagnosis

There are no characteristic laboratory abnormalities to diagnose CFS, so testing is used to rule out other potential causes for symptoms. When symptoms are attributable to certain other conditions, the diagnosis of CFS is excluded. Important conditions and disorders to exclude are current/active major depression, schizophrenia, eating disorders such as anorexia nervosa, bulimia, bipolar disorder, alcohol abuse or other substance abuse; current morbid obesity, and active medical diseases need to be resolved and excluded before a diagnosis of chronic fatigue syndrome can be made.
