Lumbar puncture (LP), also referred to as “spinal tap,” is a commonly performed procedure that involves obtaining and sampling cerebrospinal fluid from the spinal cord. It was developed by Heinrich Quincke in the late 19th Century. It is the gold standard diagnostic procedure in the diagnosis of meningitis, subarachnoid hemorrhage, and certain neurological disorders. It is also used in the measurement of intracranial pressure and administration of medications or diagnostic agents.
