CSF total protein

Normal values:

The normal protein range is 15 to 45 mg/dl.

Note: mg/dl = milligrams per deciliter

What abnormal results mean:

When the protein level increases considerably, it may indicate tumors, hemorrhage, diabetes mellitus, polyneuritis, trauma, or blood in the CSF.

When the protein level decreases, it can indicate rapid CSF production.

• chronic inflammatory polyneuropathy
• primary lymphoma of the brain
• hemorrhage - intracerebral (deep)
• hemorrhage - intracerebral (hypertensive)
• hemorrhage - intracerebral (lobar)
