Neisseria meningitidis Tetravalent Antibodies (Serogroups A, C, W-135 and Y), IgG
Use to assess immunocompetence following Neisseria meningitidis vaccination. To assess suspected immunodeficiency, use pre- and postvaccination serology. Do not use for diagnosis of infection or serotyping.
Quantitative Multiplex Bead Assay
New York DOH Approval Status
Serum separator tube. Postimmunization specimen should be drawn 30 days after immunization and, if shipped separately, must be received within 60 days of preimmunization specimen.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL) MARK SPECIMENS CLEARLY AS PRE- OR POSTPNEUMOCOCCAL VACCINE SO SPECIMENS WILL BE SAVED AND TESTED SIMULTANEOUSLY.
Refrigerated. Pre- and postpneumococcal vaccine specimens can be submitted separately or together for testing.
Plasma or other body fluids. Contaminated, hemolyzed or severely lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles).
N. meningitidis A, C, W-135 and Y, IgG:
0.9 µg/mL or less: Antibody concentration not protective.
1.0-2.0 µg/mL: Equivocal.
2.1 µg/mL or greater: Antibody to Neisseria meningitidis detected. Suggestive of protection.
Responder status is determined according to the ratio of the one month post-vaccination concentration to pre-vaccination concentration of IgG antibodies to N. meningitidis (Types A, C, Y, and W-135) as follows:
1. If the one month post-vaccination concentration is less than 3.0 µg/mL, the patient is considered to be a non-responder.
2. If the one month post-vaccination concentration is greater than or equal to 3.0 µg/mL, a patient with a ratio of greater than or equal to 4 is a good responder, a ratio of 2-4 is a weak responder, and a ratio of less than 2 is considered a non-responder
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
