Performing Lab
Lactic Acid, CSF
Clinical Use
Order TestUse
Lactic Acid levels in cerebrospinal fluid normally parallel blood levels. Increased CSF lactic acid is observed in conditions such as trauma, seizure, brain abscess, multiple sclerosis, and bacterial meningitis.
Special Instructions
Not provided.
Limitations
N‑acetylcysteine, when administered in high concentrations (e.g., for acetaminophen overdose), can interfere with the assay for lactate, leading to falsely low results.
