II. Interpretation: Increased CSF Glucose
- Reflects serum Hyperglycemia
- CSF Glucose lags Serum Glucose by 2 to 4 hours
- CSF Glucose is two thirds of Serum Glucose
- CSF Glucose does not usually rise above 300 mg/dl
III. Interpretation: Decreased CSF Glucose (Hypoglycorrhachia)
- Hypoglycemia
- Granulomatous process
- Chemical Meningitis
- Bacterial Meningitis (Protein normal in 50% of cases)
- Fungal Meningitis
- Subarachnoid Hemorrhage
- Neoplasm
- Certain CNS Viral Infections
- Herpes Simplex Virus
- Mumps
- Lymphocytic choriomeningitis
