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 liter

I found those values on MedlinePlus Medical. I'm not sure if they vary much from site to site. That was the first one I found.
