Haemophilus Influenzae (IgG) antibodies

This antibody is one of a group of antibodies commonly referred to as “functional antibodies”. The others in this designation are anti-pneumococcal and anti-Tetanus toxin. Functional antibodies are used to assess the capacity of an individual with suspected immunodeficiency to respond to challenge immunisation. When used to assess challenge immunisation a pre-challenge and a 4-6 weeks post-challenge blood sample is required. This test measures IgG antibodies to H. influenzae type b capsular antigens. The protective level is reported as 0.15 µg/ml and the optimal level > 1.0 µg/ml.
