Protein (CSF)
![](/files/tests/1534504090_csf-plain-bottle.png?03bc6a3aa6)
Background:
CSF protein may be elevated by increased permeability of the blood brain barrier (Meningitis/Guillian-Barre) or due to reduced flow of spinal CSF (disc prolapse/abscess/tumour)
CSF protein can be falsely elevated in the presence of RBCs from subarachnoid haemorrhage or traumatic LP.
Reference ranges:
