Reference IntervalNormal range/expected value(s) for a specific disease state. May also include abnormal ranges.
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
