Description
Why It’s Done:
The CSF Protein test may be ordered for several reasons:
• Diagnose infections: Such as meningitis or encephalitis.
• Detect neurological diseases: Like multiple sclerosis, Guillain-Barré syndrome, or other inflammatory conditions.
• Identify bleeding: From a brain hemorrhage or trauma.
• Monitor tumors or cancers: That involve the brain, spinal cord, or meninges.
• Assess autoimmune conditions: That affect the nervous system.
• Investigate unexplained neurological symptoms: Like severe headaches, confusion, seizures, or weakness.
Abnormal protein levels alone are not diagnostic but help guide doctors toward further testing or diagnosis.
Preparation:
• Fasting: Fasting is generally not required before a CSF protein test.
• Medication disclosure: Inform your doctor about all medications you are currently taking, including blood thinners, as they may affect the lumbar puncture procedure.
• Pre-procedure guidance: You may be advised to empty your bladder before the lumbar puncture.
• Positioning: During the lumbar puncture, you may be asked to lie on your side or sit up and lean forward to create space between your spinal bones.
