A spinal tap, also called a lumbar puncture, is a medical test in which fluid is collected from an area surrounding the spinal cord. The sample is studied for traces of bacteria and other infectious agents and is tested for blood cell count, protein, and other blood components. This test can be used to diagnose meningitis, MS, cancer, and more.
