Cerebrospinal Fluid (CSF) Protein by Manual Electrophoresis
This test measures the different types of proteins found in your cerebrospinal fluid (the fluid surrounding your brain and spinal cord). It helps identify abnormalities that may indicate conditions like inflammation, infection, or neurological disorders.

Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like headaches, neck stiffness, confusion, or neurological issues. It’s also used to monitor conditions such as multiple sclerosis, meningitis, or brain tumors. Sometimes, it’s part of a broader evaluation for unexplained neurological symptoms.
What to Expect Before the Test
You’ll likely have a small needle inserted into your lumbar spine to collect a sample of CSF. The procedure is usually quick and done in a hospital or clinic setting. You may feel pressure or mild discomfort, but it’s generally well-tolerated. Avoid heavy lifting or strenuous activity for a few hours afterward.
What the Test Results Mean
The test separates CSF proteins into bands (like albumin, globulins, and other fractions) using electrophoresis. Abnormal patterns—such as high albumin or specific globulin spikes—can signal underlying issues like inflammation, immune disorders, or metabolic problems. Your results will be interpreted by a healthcare provider based on your symptoms and medical history.
Common Conditions This Test Helps Diagnose
This test can help diagnose or monitor conditions like meningitis, encephalitis, multiple sclerosis, subarachnoid hemorrhage, or certain types of brain tumors. It may also identify metabolic disorders or immune-related diseases affecting the central nervous system.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
CSF protein electrophoresis is critical for identifying subtle but significant abnormalities that standard blood tests might miss. For example, elevated albumin in the CSF can indicate a blood-brain barrier disruption, while specific globulin bands may suggest autoimmune or infectious processes. Early detection can lead to timely treatment and better outcomes.
