What exactly is a CSF culture & what is its purpose? Is it difficult to perform and does it take longer than blood cultures for a result to come back?

What exactly is a CSF culture & what is its purpose? Is it difficult to perform and does it take longer than blood cultures for a result to come back?

Similar to blood: A CSF culture is when you take a sample of CSF (usually from a lumbar puncture which samples the CSF from the spinal canal in the lower back - so yes a bit more difficult to perform but still pretty routine) and culture it to see if there are bacteria (or sometimes viruses) growing in it, usually to look for meningitis. It takes the same amount of time as a blood culture (48 hours). ...Read more

Meningitis diagnosis: Medical diagnosis of any condition, including meningitis, rarely depends on any one lab test but also overall clinical presentation, symptoms, exam findings, etc. Viral meningitis often has mostly neutrophils in CSF early on, becoming mononuclear cells in a few days. It would be unusual to have very low CSF glucose in viral meningitis, but slightly low often is OK. Discuss w/ patient's doctor(s). ...Read more

Treatment could involve antibiotics, diuretics, steroids or surgery. ...Read more
