Cerebrospinal Fluid Protein by Electrophoresis (Qualitative)

What Does This Test Measure?

Electrophoresis separates proteins in your CSF into different bands, each representing distinct protein types. This qualitative test does not provide exact amounts but helps visualize protein distribution, which can reveal abnormalities like elevated levels of specific proteins (e.g., albumin, globulins) or unusual patterns.

Why Might You Need This Test?

Your doctor may order this test if you have symptoms like headaches, neurological issues, or signs of conditions such as meningitis, multiple sclerosis, or other spinal/central nervous system disorders. It’s also used to monitor treatment progress or rule out certain causes of symptoms.

How Is the Sample Collected?

A small amount of CSF is collected via a procedure called a lumbar puncture (spinal tap). A doctor inserts a needle into your lower back to draw fluid from the spinal canal. This is usually done in a hospital setting with sedation or local anesthesia.

What Are Common Results?

Results are qualitative, meaning they describe patterns rather than specific values. Normal results show typical protein distribution, while abnormal patterns may indicate inflammation, infection, or other underlying issues that require further evaluation.
