For assessment of immunization efficacy with the Haemophilus influenzae type b (Hib) vaccine. As a guide, a concentration of Haemophilus infleunzae type b IgG antibodies of 0.15 mg/L is generally accepted as the minimum level required for protection. When the postvaccinations to prevaccination ratio is >4, the patient is considered a good responder.

Serum should be obtained 3-4 weeks after primary immunization or 2-3
weeks after booster if clinically indicated and tested simultaneously
with the pre-vaccination sample. Pre- and post-vaccination sera
must be sent together. Please label the tubes "pre" and "post"
so that the sera can be assayed simultaneously.
