Cerebrospinal Fluid (CSF) Protein by Fluorescence Immunoassay (Qualitative)

Why This Test Is Done

Your doctor may order this test if you have symptoms like severe headaches, neck stiffness, confusion, or neurological problems. It’s often used alongside other tests, such as a lumbar puncture, to investigate conditions like infections, inflammation, or tumors in the central nervous system.

What to Expect Before the Test

You’ll typically undergo a lumbar puncture (spinal tap) where a small needle is inserted into your lower back to collect CSF. The procedure is usually quick and done in a hospital setting. No special preparation is needed, but inform your doctor about any medications you’re taking.

What the Results Mean

Protein levels in CSF can vary widely depending on the underlying condition. Elevated protein levels may suggest conditions like meningitis, multiple sclerosis, or brain tumors. Lower-than-expected levels might indicate issues with CSF production or circulation. Your doctor will interpret the results in the context of your symptoms and other tests.

Common Conditions This Test Helps Diagnose

This test is particularly useful for diagnosing or monitoring conditions such as viral or bacterial meningitis, encephalitis, subarachnoid hemorrhage, brain tumors (like gliomas), and inflammatory diseases like multiple sclerosis.
