What is the CSF Biochemistry Test?

The CSF Biochemistry Test evaluates important biochemical substances present in cerebrospinal fluid (CSF), the clear fluid surrounding the brain and spinal cord. It helps diagnose conditions such as bacterial, viral, or fungal meningitis, encephalitis, neurological disorders, bleeding into the brain, and certain autoimmune diseases affecting the central nervous system.

Who should take this test?

• Patients with suspected meningitis or encephalitis.
• Individuals with severe headache, neck stiffness, fever, or confusion.
• Patients with suspected neurological or inflammatory disorders.
• Individuals being evaluated for multiple sclerosis or other central nervous system diseases.
• Patients with unexplained seizures or altered consciousness.
• Doctor-recommended investigation of brain or spinal cord disorders.

Understanding Your Results

Abnormal protein, glucose, chloride, or lactate levels may indicate infections, inflammation, bleeding, autoimmune disorders, or other diseases affecting the central nervous system.

Normal values vary depending on age and the laboratory performing the test.

Results should always be interpreted together with your symptoms, neurological examination, CSF cell count, microbiology results, imaging studies, and your treating physician’s assessment.
