BACTERIAL MENINGITIS PANEL 5 ANTIGENS, SERUM

Bacterial Meningitis Panel 5 Antigens, Serum

What it is

The Bacterial Meningitis Panel 5 Antigens, Serum test is a diagnostic blood test used to detect antigens from five common bacteria that cause meningitis. By identifying these bacterial antigens, the test helps doctors quickly diagnose bacterial meningitis and guide appropriate treatment.

Uses

This test is primarily used to detect bacterial meningitis in patients with suggestive symptoms. It helps confirm the presence of infection, determine the specific bacterial cause, and initiate the correct antibiotic therapy. It may also be used in outbreak situations for rapid diagnosis.

Symptoms That May Lead to the Test

Doctors may order this test if a patient shows symptoms such as sudden high fever, severe headache, stiff neck, nausea, vomiting, sensitivity to light, altered mental status, or seizures. In infants, symptoms may include irritability, poor feeding, or bulging fontanelle.

Abnormal Results

Positive Result: Indicates the presence of one of the five bacterial antigens linked to bacterial meningitis. This confirms bacterial infection and requires urgent treatment.

Negative Result: Suggests no detectable bacterial antigens. However, it does not rule out meningitis completely, as the infection may be viral or caused by less common bacteria.

Risks

The test involves a routine blood draw and carries minimal risks. Possible side effects include mild pain, bruising, or bleeding at the puncture site, and in rare cases dizziness or infection.
