glucose in CSF

Reference values: - 40-70 mg/dL (CSF) Clinical significance: - low CSF glucose with normal serum glucose is consistent with bacterial meningitis Decreases: - bacterial meningitis Principle: see glucose in serum/urine/CSF Specimen: No special patient preparation is required. Collect cerebrospinal fluid specimens by standard sterile procedure. (see lumbar puncture) Hemolyzed specimens should not be used. Freeze specimen if not analyzed immediately. CSF specimens are sometimes contaminated with bacteria & other cellular constituents that lower the concentration of glucose with time. Minimum sample required is 0.5 milliliter with an optimum size of 1.0 milliliter or larger.
