Neurology® Podcast CSF Correction Factors for Traumatic Lumbar Puncture in Adults
Jan 16, 2025
Dr. Adrian Budhram, a neurologist known for his expertise in autoimmune encephalitis, discusses the complexities of cerebrospinal fluid (CSF) analysis after traumatic lumbar punctures. He highlights the challenges neurologists face with red and white blood cell contamination and the research gaps in correction factors for accurate diagnoses. Patient anxiety during these procedures also becomes a focal point, emphasizing the importance of effective doctor-patient communication. Ultimately, the conversation stresses the significance of clinical judgment in interpreting CSF results.

Episode notes
Four-Tube CSF Collection
- Ideally, collect CSF in four tubes to avoid contamination.
- Analyze tube four, as it's less likely to have blood contamination.
Correction Factor Usage
- Simple correction factors are commonly used for traumatic LPs.
- These involve subtracting a fixed number of white blood cells per a certain number of red blood cells.
Limited Research on Correction Factors
- The simpler correction factors are easier to apply, but their efficacy isn't well-documented.
- Literature on correction factors for adults is surprisingly sparse.
