Why This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms like headaches, neurological issues, or signs of an infection/inflammation in your central nervous system. It’s also used to monitor conditions like multiple sclerosis, meningitis, or brain tumors.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your lumbar spine to collect a small amount of cerebrospinal fluid. The procedure is quick and usually painless, though you may feel mild pressure or a slight ache afterward.

What the Results Mean

Elevated protein levels could indicate conditions like Guillain-Barré syndrome, multiple sclerosis, or infections. Lower-than-expected levels may suggest bleeding or other rare conditions. Results are interpreted by your doctor in the context of your symptoms and medical history.

Common Conditions This Test Helps Diagnose

This test supports diagnosing neurological disorders, infections (e.g., meningitis), or inflammatory diseases affecting the central nervous system. It may also help assess the effectiveness of treatments for these conditions.
