This test is done to see if myelin is breaking down.
- Bleeding of the central nervous system
Central nervous system trauma

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.
The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.
What abnormal results mean
Myelin basic protein levels between 4 and 8 ng/mL may be a sign of a
If the myelin basic protein level is greater than 9 ng/mL, myelin is actively breaking down.
