Pronunciation: [lˈʌmbɑː pˈʌŋkt͡ʃə] (IPA) 
Lumbar puncture is a diagnostic medical procedure that involves inserting a needle into the lower back to collect cerebrospinal fluid (CSF) for testing. There are several synonyms for lumbar puncture, including spinal tap, spinal puncture, and LP. These terms are often used interchangeably, but they all refer to the same procedure. A lumbar puncture may be performed to help diagnose conditions such as meningitis, multiple sclerosis, or cancer.

Patients should discuss the risks and benefits of a lumbar puncture with their healthcare provider before undergoing the procedure.
