Test Code: 1121
Expand All Collapse All
Clinical Utility

A common method for evaluating suspected antibody deficiency is to immunize the patient with an appropriately selected vaccine, such as Tetanus, and determine vaccine-specific antibody concentrations in a serum sample 3-4 weeks post-immunization compared to a pre-immunization sample.

Procedure

The Haemophilus influenza type B capsular polysaccharide is used as a solid phase antigen in a sensitive microtiter EIA. The assay is calibrated against the standard from the Centre for biologics Evaluation and Research, US Food and Drug Administration: Lot 1983. The minimal protective level in non-vaccinated individuals is greater than or equal to 0.15 mcg/mL. The protective level expected in recently vaccinated individuals is greater than or equal to 1.0 mcg/mL. This test has been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
