What is a normal finding for the spinal fluid of a lumbar puncture?

Normal lumbar puncture (LP) cerebrospinal fluid (CSF) findings include the following: Appearance: Clear. Opening pressure: 10-20 cm H2 O. WBC count: 0-5 cells/µL (< 2 polymorphonucleocytes [PMN]); normal cell counts do not rule out meningitis or any other pathology.

What are they looking for when they do a lumbar puncture?

During a spinal tap (lumbar puncture), a healthcare provider withdraws cerebrospinal fluid. This test can detect meningitis, leukemia and other illness. Providers also use spinal taps to give spinal anesthesia (epidural) and medications.

Is a spinal tap necessary to diagnose MS?

MS is often difficult for doctors to diagnose because a spinal tap alone can’t prove whether you have MS. In fact, there’s 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.

What drugs can be detected in a spinal tap?
