CSF Total Protein
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
The CSF Total Protein measurement is a cornerstone of CSF Biochemical Analysis. Normally, the blood-brain barrier (BBB) restricts the entry of large proteins into the cerebrospinal fluid. Elevated protein levels indicate increased permeability of the BBB or local immunoglobulin synthesis within the central nervous system. It is vital for diagnosing meningitis, multiple sclerosis, Guillain-Barré syndrome, and CNS tumors.

Why Context Matters
A 'traumatic tap' (contamination with peripheral blood during the procedure) can artificially elevate protein levels. Additionally, protein concentration varies significantly based on the site of collection (ventricular vs. lumbar) and the age of the patient.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
