Lumbar punctures usually take place in a doctorâs office â most often a neurologist â that has been equipped to do this procedure. Who will be in the room with my child during the procedure? Your child will be with her doctor or nurse practitioner performing the lumbar puncture, and a nurse or clinical assistant who will help.
A lumbar puncture may be performed for various reasons. The most common reason is to remove a small amount of CSF for examination and diagnosis of various disorders. CSF is tested for red and white blood cells, protein, glucose (sugar), clarity, color, and the presence of bacteria, viruses, or abnormal cells.
