What is the CSF Microprotein Test?

The CSF Microprotein Test, also known as the CSF Protein Test, measures the amount of protein present in the cerebrospinal fluid. Normally, only a small amount of protein is found in CSF. Increased protein levels may indicate infection, inflammation, bleeding, nerve damage, tumors, or disorders affecting the brain and spinal cord.

Who should take this test?

• Patients with suspected meningitis or encephalitis.
• Individuals with severe headache, fever, neck stiffness, or altered consciousness.
• Patients being evaluated for multiple sclerosis or other neurological disorders.
• Individuals with suspected bleeding around the brain or spinal cord.
• Patients with unexplained seizures or neurological symptoms.
• Doctor-recommended comprehensive CSF evaluation.

Preparation & Test Process

Understanding Your Results

Elevated CSF protein levels may indicate bacterial or viral meningitis, multiple sclerosis, Guillain-Barré syndrome, brain or spinal tumors, bleeding, inflammation, or nerve injury.

Low CSF protein levels are uncommon but may occur due to leakage of cerebrospinal fluid or excessive CSF production.

Results should always be interpreted together with CSF glucose, cell count, microbiological tests, imaging findings, and your physician’s clinical assessment.
