Cell Count: Normal CSF contains very few cells. An increased cell count, especially of white blood cells, may indicate an infection or inflammation. Protein Levels: Elevated protein levels can be a sign of blood-brain barrier disruption, infections, or inflammatory conditions. Glucose Levels: Low glucose levels in CSF may indicate bacterial or fungal infections. Microbial Analysis: Detecting bacteria, viruses, or fungi can help diagnose specific infections. This often involves culture techniques and molecular methods like PCR. Immunoglobulins: Elevated levels of immunoglobulins, particularly IgG, can indicate autoimmune conditions like multiple sclerosis.
