Order Diphtheria Antibody Test | Immunity TestingThe Diphtheria Antibody Test measures the level of antibodies produced against diphtheria toxoid, the inactivated toxin used in vaccination. This blood test helps determine whether an individual has protective immunity from prior vaccination or, in some cases, from natural exposure. It is a quantitative test, meaning it reports a numerical value rather than a simple positive or negative result.
About Diphtheria Antibody Test | Immunity Testing in Berkeley
Diphtheria is a serious bacterial infection caused by toxin-producing strains of Corynebacterium diphtheriae. Immunity is primarily achieved through vaccination with diphtheria toxoid, which stimulates the body to produce neutralizing antibodies.
The test works by measuring the concentration of IgG antibodies specific to diphtheria toxoid in the blood. Results are typically reported in international units per milliliter (IU/mL), and a threshold value is used to indicate whether the level is likely protective.
This test is often used to assess immune status in individuals with uncertain vaccination histories, those who may have received incomplete series, or in certain occupational or travel-related contexts where documentation of immunity is needed. It can also be used to evaluate response following vaccination.
Antibody levels can decline over time, and a low result does not necessarily mean a person is unprotected, as immune memory may still provide rapid response upon exposure. Interpretation should always be made by a healthcare provider in the context of clinical history and vaccination records.
