Quizplus · Accepted Answer

Lumbar puncture is commonly used to collect a sample of cerebrospinal fluid (CSF) for laboratory testing. CSF is the clear, colourless liquid that surrounds the brain and spinal cord, protecting them from injury and infection. Examination of the CSF can help diagnose a number of medical conditions, including infections, multiple sclerosis, and certain types of cancer.
