Description
Why It’s Done:
The Neisseria meningitidis Antigen (CSF) Test is performed to:
• Diagnose meningococcal meningitis: It helps confirm the presence of Neisseria meningitidis as the causative agent of bacterial meningitis.
• Detect meningococcal infections early: Rapid detection of the antigen allows for quick diagnosis and treatment to prevent serious complications.
• Confirm meningococcal septicemia in patients with bloodstream infections who are at risk of developing meningitis.
• Monitor treatment progress in patients undergoing therapy for meningococcal infections.
• Assist in differentiating bacterial from viral meningitis, as meningococcal meningitis requires immediate antibiotic treatment.
Preparation:
• No special preparation or fasting is required for this test.
• The test requires a cerebrospinal fluid (CSF) sample, which is typically obtained through a lumbar puncture (spinal tap). The procedure should be performed by a healthcare professional.
• Post-procedure care: After the lumbar puncture, the patient may be advised to rest and drink fluids to reduce the risk of a headache from the procedure.
• Inform your healthcare provider about any recent infections or antibiotic treatments, as these may affect test results.
