Reference Interval

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
