In brief: Lumbar puncture (LP)

Cerebrospinal fluid (CSF) bathes brain & spinal cord (cns).
CSF may be abnormal in some diseases. In an lp, you are either on your side or sitting. Md feels lower back for interspace between 4th & 5th lumbar vertebrae, below end of cns. Lidocaine is injected. 3” hollow needle is inserted thru interspace & into sac holding CNS & csf. Md collects CSF (usually ~1 tsp) into 3-4 tubes. CSF sent to lab.
