Protein, CSF

Diagnostic Use

CSF protein is largely an ultrafiltrate of plasma, and is predominantly made up of low molecular weight and medium molecular weight proteins. In normal health, the protein concentration of CSF is approximately 100-fold less than that of plasma.

There are many causes of an elevated CSF protein. Therefore this test is a non-specific biomarker of CNS pathology that may be of some diagnostic use when applied to the relevant clinical context.
