Curious, I don't have my LP results any longer. Way too many years ago but a positive LP (meaning possibly MS) requires oligoclonal bands (o-bands) which will usually mean the patient has high protien (IGg - if I have that correct).

LPs are not just to diagnose MS. There are other diseases where you can have an abnormal LP.

CSF oligoclonal banding is a test to look for inflammation-related substances in the cerebrospinal fluid (CSF), the clear fluid that flows in the space surrounding the spinal cord and brain.
Oligoclonal bands are substances called immunoglobulins, which suggest inflammation of the central nervous system. The presence of oligoclonal bands may be a sign of multiple sclerosis.

Normal values vary from lab to lab but typically range as follows:

• Pressure: 50 - 180 mm H20
• Appearance: clear, colorless
• CSF total protein: 15 - 45 mg/100 mL
• Gamma globulin: 3 - 12% of the total protein
• CSF glucose: 50 - 80 mg/100 mL (or approximately 2/3 of blood sugar level)
• CSF cell count: 0 - 5 white blood cells, no red blood cells
• Chloride: 110 - 125 mEq per liter

Note: mg/mL = milligrams per milliliter; mEq/L = milliequivalent per
