Quizplus · Accepted Answer

A cerebrospinal fluid analysis, commonly known as a spinal tap, is a diagnostic test that involves the removal of a small amount of cerebrospinal fluid (CSF) from the space around the brain and spinal cord. This fluid is then examined for abnormalities that may indicate certain neurological conditions, such as infections, inflammation, or bleeding. PET, complete blood count, myelogram, and myelotomy are not tests that examine fluid surrounding the brain and spinal cord.
