Introducing a needle between the lower bony vertebrae of our spinal column allows a physician to sample the fluid (Cerebrospinal Fluid (CSF)) surrounding the brain and spinal cord. Laboratory tests on the fluid are used for diagnostic purposes such as presence of bacteria in Meningitis, special proteins in Multiple Sclerosis (MS) or blood cells! What is the procedure called?
1) Lumbar puncture
2) Spinal tap
3) Cerebrospinal fluid analysis
4) Brain biopsy
