Podcast 556: CSF - What is it good for?

Contributor: Eric Miller, MD

Educational Pearls:

  • A cell count is performed on tubes 1 and 4 to account for changes that may occur from blood entering the first sample from the needle insertion
  • Tube 2 and 3 are usually used for the other studies like protein levels, glucose levels and gram staining
  • Protein levels are often elevated in bacterial meningitis but can be helpful in diagnosis conditions like multiple sclerosis
  • Glucose levels are typically low in bacterial meningitis due to the use of glucose by bacteria
  • Cell counts above 3-5 cells are typically abnormal, but cell counts can vary widely depending on the type of meningitis (viral vs. bacterial) and how long the infection has been present.
  • Cell type and differential can indicate viral vs. bacterial meningitis
    • Neutrophils are more associated with bacterial causes
    • Lymphocytes are more associated with viral etiologies
  • CSF cultures are used to identify the cause of bacterial meningitis but can take days to result.
  • A gram stain can help determine if any bacteria are present as well as cell types present.
