Cerebrospinal Fluid (CSF) Analysis

The Cerebrospinal Fluid (CSF) Analysis at Pamel Laboratories is a comprehensive diagnostic test performed on a sample of cerebrospinal fluid — the clear, protective fluid surrounding the brain and spinal cord. This test helps detect serious neurological conditions, infections, hemorrhages, and inflammatory disorders affecting the central nervous system.

Often performed following a lumbar puncture (spinal tap), CSF analysis provides critical information for diagnosing conditions like meningitis, encephalitis, multiple sclerosis, and subarachnoid hemorrhage.

What the Test Measures:

• Physical appearance of CSF (color, clarity)

• Cell counts: White blood cells (WBCs), red blood cells (RBCs)

• Glucose and protein levels

• Chloride levels

• Microbiological examination (e.g., Gram stain, AFB, cultures)

• Cytology (if cancer or malignancy is suspected)

Purpose of the Test:

• Diagnose or monitor:

  • Meningitis (bacterial, viral, or fungal)

  • Encephalitis

  • Brain or spinal cord inflammation

  • Bleeding in the brain (subarachnoid hemorrhage)

  • Neurological autoimmune disorders (e.g., multiple sclerosis)

  • Cancers of the brain or spinal cord

Sample Type: Cerebrospinal fluid (collected via lumbar puncture)
Fasting Required: No
Turnaround Time: 24–72 hours (depending on the tests requested)

Important Notes:

• Interpretation must be done in clinical context with symptoms such as fever, neck stiffness, seizures, confusion, or headache

• CSF testing may include special stains, cultures, or PCR tests for detecting infections

• Specimens must be handled and transported immediately and carefully
