A spinal tap, also called lumbar puncture, is a procedure in which the fluid surrounding the spinal cord and the brain (called the cerebrospinal fluid, or CSF) is withdrawn through a needle and examined in a lab.

Testing the CSF can help in the diagnosis of disorders of the central nervous system that may involve the brain, spinal cord, or their coverings (meninges).
