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.


Tetanus Toxoid is used as a solid phase antigen in a sensitive microtiter EIA. Calibrators are referenced to the antitoxin reference preparation 76/589. The recommended protective level is greater than or equal to 0.10 IU/mL. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
