#ExistRefRange>Antibody concentration of > 0.1 IU/mL is usually considered protective.
#ExistInterpData>Responder status is determined according to the ratio of a one-month post-vaccination specimen to pre-vaccination concentration of diphtheria IgG antibody as follows:
1. If the post-vaccination concentration is less than 1.0 IU/mL, the patient is considered a nonresponder.
2. If the post-vaccination concentration is greater than or equal to 1.0 IU/mL, a patient with a ratio of less than 1.5 is a nonresponder, a ratio of 1.5 to less than 3.0, is a weak responder, and a ratio of 3.0 or greater, is a good responder.
3. If the pre-vaccination concentration is greater than 1.0 IU/mL, it may be difficult to assess the response based on a ratio alone. A post-vaccination concentration above 2.5 IU in this case is usually adequate.
