What is a lumbar puncture (LP)? A lumbar puncture (LP) is the insertion of a needle into the fluid within the spinal canal to collect and examine the fluid that surrounds the brain and spinal cord (cerebral spinal fluid). It is termed a lumbar puncture because the needle is placed in the lumbar portion of the back and used to puncture through tissues to enter the spinal canal. Other names for a lumbar puncture (an LP) include spinal tap, spinal puncture, thecal puncture, and rachiocentesis.
