Method Sodium and potassium cations were calibrated (and continuously verified) with NIST-certified standard mixtures (SPEX CertiPrep, Metuchen, NJ, USA). The osmolarity of 50 µL of CSF was determined in a freezing point osmometer, the 5004 Micro-Osmette™, calibrated with 100 and 500 mosmol reference standards (Precision Systems, Inc., Natick, MA, USA).
Comments The mean 24-h CSF protein was 329±69µg/mL, sodium was 150.6±10.9mM, potassium was 2.96±0.7mM, and osmolarity was 355±39.1mOsmol.
