Cerebrospinal fluid: raised protein

Cerebrospinal fluid: raised protein

Normal values of cerebrospinal fluid (CSF) are as follows:
  • pressure = 60-150 mm (patient recumbent)
  • protein = 0.2-0.4 g/l
  • glucose = > 2/3 blood glucose
  • cells: red cells = 0, white cells < 5/mm³

The following conditions are associated with raised protein levels
  • Guillain-Barre syndrome
  • tuberculous, fungal and bacterial meningitis
  • Froin's syndrome*
  • viral encephalitis

*describes an increase in CSF protein below a spinal canal blockage (e.g. tumour, disc, infection)
