Testing for MS – Lumbar puncture
Language
Description
A Lumbar Puncture (spinal tap) is a useful tool that can help doctors diagnose MS. During this test, a doctor takes a small sample of the fluid around your brain and spinal cord, called cerebrospinal fluid, or CSF. The sample is sent to a lab for signs of MS, such as antibodies in the fluid. These antibodies indicate that your immune system is active in your brain and spinal cord.
