Clinical Significance

Used in the diagnosis and treatment of conditions such as meningitis, brain tumors, and infections of the central nervous systems.

Most CSF protein originates by diffusion from plasma across the blood-CSF barrier. Elevated levels occur as a result of increased permeability of the blood-CSF barrier or with increased local synthesis of immunoglobulins.
