Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of multiple sclerosis and other demyelinating conditions

 

Evaluation of patients presenting with a clinically isolated syndrome, which is a clinical episode where patient reports symptoms (headaches, optic neuritis, fatigue and many others, depending on the disease location) characteristic of inflammation and demyelination of the central nervous system

 

A testing recommendation in cases where the imaging findings are atypical, and in populations in which multiple sclerosis is less common (eg, children, older individuals, or non-white populations)

 

The test is not useful when a clear diagnosis is already known because a positive result does not correlate with severity of the disease or disease outcomes.
