CSF Albumin
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Albumin is not produced in the central nervous system; therefore, its presence in the Cerebrospinal Fluid (CSF) is derived entirely from the blood. In the 'CSF Biochemical Analysis' panel, it is the gold standard marker for assessing the integrity of the Blood-Brain Barrier (BBB). An increase in CSF albumin indicates that the barrier is 'leaky,' which occurs in infections, tumors, or inflammatory conditions.

Why Context Matters
A 'traumatic tap' (where blood enters the CSF during the puncture procedure) can artificially elevate CSF albumin levels. To distinguish between true pathology and procedure-related contamination, the result should ideally be interpreted as part of the 'Albumin Index' (CSF Albumin / Serum Albumin ratio).
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
