Monocyte and Macrophage Protein Levels in Cerebrospinal Fluid (CSF)

Why This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms like headaches, neck stiffness, confusion, or neurological issues that suggest inflammation or infection in the brain or spinal cord. It could also be part of a broader evaluation for autoimmune diseases or conditions affecting the central nervous system.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your lower back to collect a small amount of spinal fluid. You may feel a brief pinch, but it’s usually over quickly. You’ll lie on your side for a few minutes afterward to prevent any leakage.

What the Results Mean

Higher-than-normal levels of these proteins may indicate inflammation, infection, or immune activity in your spinal fluid. Lower-than-normal levels might suggest reduced immune response or certain neurological disorders. Your doctor will interpret results in the context of your symptoms and medical history.

Common Conditions This Test Helps Diagnose

This test can help diagnose or monitor conditions such as multiple sclerosis, meningitis, encephalitis, or other inflammatory or infectious processes in the central nervous system.
