In general there should be less than 4 ng/mL of myelin basic protein in the CSF.

Note: ng/mL = nanogram per milliliter

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

Myelin basic protein levels between 4 and 8 ng/mL may be a sign of a chronic breakdown of myelin, or recovery from an acute episode of myelin breakdown.

If the myelin basic protein level is greater than 9 ng/mL, myelin is actively breaking down.
