Your doctor will recommend 

• To stop any blood thinning medications or any other drugs, a few days before the procedure.
• CT scan of brain, to rule out any abnormal swelling in or around the brain.
• To empty the bladder before the procedure.

The procedure lasts up to 40 to 60 minutes. During the procedure,

• You will be asked to lie down on one side with knees drawn up to the chest or sit leaning forward with head and chest bent over the knees. 
• The lumbar area on the lower back from where the fluid will be withdrawn is marked, cleaned with aseptic solution and local anesthetic is injected to numb the area.
• Under local anesthesia, a long thin needle is inserted between the two lumbar vertebrae on the lower back to withdraw a sample of cerebrospinal fluid. 

There will be some pain and tenderness in the lower back after the procedure. Pain killers will be prescribed for the pain.

The cerebrospinal fluid that is collected is analyzed for texture, white blood cell count, glucose level, protein concentration and cancerous cells. Cultures of CSF samples are done when infections are suspected.

Although rare, there may be some side effects of spinal tap. Commonly known are

• Bleeding near the puncture site.
• Headache due to leak of cerebrospinal fluid to nearby tissues causing nausea, vomiting and dizziness.
• Increased intracranial pressure can lead to compression of the brain stem after CSF sample is removed.
