I found this on the internet. I had read this before also. You probably had some bleeding or trauma during the tap. My docs never tell me when things are "slightly off" either. I don't understand why there are guidelines and then they excuse them when they are not way off! LOL!
PROTEIN Total protein levels in CSF are normally very low, and albumin makes up approximately two-thirds of the total. High levels are seen in many conditions, including bacterial and fungal meningitis, tumors, subarachnoid hemorrhage, and traumatic tap.
