Neisseria meningitidis Tetravalent Antibodies (Serogroups A, C, W-135 and Y), IgG
Also known as: NMENING
Use
This test is used to assess immunocompetence following Neisseria meningitidis vaccination. It evaluates the levels of IgG antibodies against four serogroups (A, C, W-135, and Y) to determine the protective response after vaccination. A low concentration suggests a lack of protection, while higher levels indicate a protective antibody response.
Special Instructions

Limitations
This test should not be used for diagnosing an active infection or for serotyping Neisseria meningitidis. It is specifically designed for assessing antibody response post-vaccination and may not reflect the immune status related to ongoing or past infections. The test is developed by ARUP Laboratories and not FDA-approved.
