What are normal lumbar puncture results?
Normal Results Appearance: clear, colorless. CSF total protein: 15 to 60 mg/100 mL. Gamma globulin: 3% to 12% of the total protein. CSF glucose: 50 to 80 mg/100 mL (or greater than two thirds of blood sugar level)
What diseases can be diagnosed with a lumbar puncture?
A lumbar puncture procedure may be helpful in diagnosing many diseases and disorders, including:
- Meningitis.
- Encephalitis.
- Certain cancers involving the brain and spinal cord.

- Reye syndrome.
- Myelitis.

What does high glucose in spinal fluid mean?
Glucose levels in CSF are compared with blood plasma levels of glucose. CSF protein concentration. Increases may mean brain or spinal cord disease. CSF leukocyte, or white blood cell, count. It’s usually high if you have an infection.
What is considered high protein in CSF?
The CSF protein content is almost always elevated in bacterial meningitis (Tables 20-1 and 20-2). Several studies have shown that protein levels are increased at least to some degree in more than 95% of patients, and its absolute value is over 80 mg/dl in more than 80% of patients.
Does high protein in CSF mean MS?
Cerebral Spinal Fluid Studies Oligoclonal Immunoglobulin Bands can be identified in the CSF of MS patients via electrophoresis. The overall protein level is also slightly elevated – up to 0.1 g/L. Protein level can be higher if the patient is going through a marked relapse (i.e.,. severe optic neuritis).
What is the normal range of protein in CSF?
The normal protein range varies from lab to lab, but is typically about 15 to 60 milligrams per deciliter (mg/dL) or 0.15 to 0.6 milligrams per milliliter (mg/mL).
Why is protein increased in CSF in meningitis?
CSF protein Bacterial meningitis leads to a more permeable blood brain barrier (due to increased inflammation). Protein leaks into the subarachnoid space from the blood, resulting in markedly increased CSF protein levels.
