Testing for MS
The earlier that testing is done, the more steps can be taken to prevent rapid progression of multiple sclerosis. The McDonald criteria used in testing for MS includes a spinal fluid evaluation, and MRI scanning for tracking lesions in the central nervous system over time. Disorders that mimic MS are Lyme disease, chronic fatigue syndrome, fibromyalgia, AIDS, lupus and other autoimmune conditions. Blood tests may be conducted to rule out other disorders. Multiple sclerosis severity is measured by using the Expanded Disability Status Scale.
