• Cell count: less than 5 white blood cells (WBC) and 0 red blood cells (RBC)
• Culture and sensitivity: no organism growth
• Protein: 15 to 45 mg/dL
• Glucose: 50 to 80 mg/100 mL
• Serology for syphilis: no presence of antibodies
• Fungus: no presence of fungus
• Immunofixation: 1 or 0 bandings
• Glutamine: 6 to 15 mg/dL
• Lactate dehydrogenase: less than 2.0 to 7.2 U/mL
• Chloride: 700 to 750 mg/dL
• Cytology: no malignant cells present

Abnormal glutamine results may indicate hepatic encephalopathy or Reye's syndrome. Elevated lactate dehydrogenase levels may indicate inflammation or infection. Decreased glucose may suggest meningitis due to bacteria, fungus, or tuberculosis. Increased white blood cells may indicate an infection or another inflammatory process.
