Are you awake for a spinal tap?
A spinal tap is done in the lower lumbar area, below the point where the spinal cord ends. So, the risk of harming the spinal cord is avoided. A lumbar puncture is not a surgery. So someone getting one might be awake during it, and won’t need stitches or extended recovery time.
How long does it take for a spinal tap to come back?
Simple tests are ready the same day, if not within a few hours. If we’re looking for bacteria, we’ll know the results within 72 hours. Other, more demanding tests may be ready in a matter of days or weeks; and specific biochemical tests that are looking for certain antibodies may take six to eight weeks to come back.
What diseases can be found in spinal fluid?
A CSF analysis may include tests to diagnose:
- Infectious diseases of the brain and spinal cord, including meningitis and encephalitis.
- Autoimmune disorders, such as Guillain-Barré Syndrome and multiple sclerosis (MS).
- Bleeding in the brain.
- Brain tumors.
Does a Spinal Tap hurt?
Do spinal taps hurt? Spinal tap pain is rare, though sometimes the needle may brush by a nerve root as it’s inserted. “That can feel like a little zing or electric shock down one leg or the other.
Does a Spinal Tap hurt more than an epidural?
In most people, a spinal tap causes no more than a small amount of discomfort.

Because the needle is inserted well below where the spinal cord ends, there is almost no chance of nerve damage or paralysis.
Can I go to work after a lumbar puncture?
Avoid strenuous activity for the first 24 hours after the procedure. You can return to all your usual activities such as work and driving, as soon as you feel well enough after that. Some of the test results from the lumbar puncture will take a few days, but others can take several weeks.
What drugs can be detected in a spinal tap?
Classes of drugs evaluated in this study included: benzodiazepines, anticonvulsants, sedatives, opioids, antidepressants, anesthetics, and antihistamines. The majority of the drugs tested were readily detected in CSF specimens. The average CSF/blood ratio for most drugs was in the range of 0.05-0.50.
What happens if you lose all your spinal fluid?
The tear or hole allows the CSF to leak out. The loss of CSF causes the previously cushioned brain to sag inside the skull, which results in a headache. Loss of fluid also causes a lowering of pressure within the skull, a condition called intracranial hypotension.
What does bacteria in spinal fluid mean?
Bacteria or other germs found in the sample may be a sign of meningitis. This is an infection of the membranes covering the brain and spinal cord. The infection can be caused by bacteria, fungi, or viruses.
Why does the physician order a test in the spine to diagnose a problem in the head?
If you have headaches or migraines, your doctor may use a spinal tap to look for signs of infection, bleeding in the brain, to measure the pressure around your brain, or other things that could be causing your pain.

Does a Spinal Tap show MS?
MS is often difficult for doctors to diagnose because a spinal tap alone can‘t prove whether you have MS. In fact, there is no single test that can confirm or deny a diagnosis. Other tests include an MRI to detect lesions on your brain or spinal cord, and an evoked potential test to help detect nerve damage.
Why is a spinal tap so painful?
There are lots of nerves within the fluid in the spinal canal but usually they have room to move out of the way. If one of the nerves is touched, it can give a nasty ache or pain, usually in a leg. Once the needle is in the right place, it takes a few seconds to get the sample.
