During a lumbar puncture, a needle is placed in your back to collect cerebrospinal fluid (CSF). Care of the puncture site, expected complications, and instructions for bathing, activity, and diet are outlined. A list of symptoms that require immediate medical attention are provided.
This test is sometimes called a spinal tap. A small amount of fluid is taken out from the space around your spinal cord that is fluid-filled. The cells in the fluid are studied under a microscope in a lab to check for any problems.This pamphlet explains how the test is done, how long it takes and follow-up care.
