Reference Interval

< 1.0 µg/mL = Antibody concentration not protective.
≥ 1.0 µg/mL = Antibody to H. influenzae b detected. Suggestive of protection.

Interpretive Data

Responder status is determined according to the ratio of post-vaccination concentration to pre-vaccination concentration of Haemophilus influenza b antibody, IgG as follows:
1.  If the post-vaccination concentration is less than 3.0 µg/mL, the patient is considered to be a nonresponder.
2.  If the 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 nonresponder.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
