Remarks
  
Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)  
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.
