About Diphtheria Antibody Test | Immunity Testing in San Rafael
Diphtheria is a serious bacterial infection caused by toxin-producing strains of Corynebacterium diphtheriae. Antibodies against the diphtheria toxoid are produced after vaccination or infection and are considered a marker of immune protection.
The test quantifies serum antibody levels to diphtheria toxoid using standardized immunoassay methods. Results are typically reported in international units per milliliter (IU/mL), with established thresholds indicating protective, indeterminate, or non-protective antibody concentrations.
Antibody levels can decline over time, and this test is often used to assess whether an individual maintains adequate immunity. It does not diagnose active diphtheria infection; rather, it evaluates humoral immune status related to the toxoid antigen.
Interpretation of results should consider vaccination history, age, and clinical context. A healthcare provider can determine whether additional vaccination or other follow-up is appropriate based on the measured antibody level.
