what tests are taken to diagnose ms
No single set of symptoms or laboratory test, such as a blood test, imaging test, genetic test, or immune function test, can independently identify MS. A doctor must use multiple tools to diagnose MS. The most important tools are the medical history, a careful and thorough neurologic exam, and magnetic resonance imaging (MRI). Other tests include visual evoked potentials (VEP) and analysis of spinal fluid taken by lumbar puncture.
