Cerebral spinal fluid (CSF) is a clear fluid that circulates in the
space surrounding the spinal cord and brain. CSF protects the brain
and spinal cord from injury by acting like a liquid cushion. CSF is
usually obtained through a lumbar puncture (spinal tap). During the
procedure, a needle is inserted usually between the 3rd and 4th
lumbar vertebrae and the CSF fluid is collected for testing
