Diphtheria Titer Blood Test

This titer test is used to check for immunity to Diphtheria by measuring the level of protective antibodies.  Diphtheria is caused by a bacterial infection that typically attacks the respiratory system.  Infections can be fatal if not properly treated. 

Vaccinations for Diphtheria may require boosters approximately every ten years to maintain immunity.  Titer testing in advisable for anyone who is unsure of the status of their immunity, especially people who believe they have come into contact with a person suffering from a Diphtheria infection.  Anyone traveling to a part of the world where Diphtheria is common should verify the status of their immunity. 

The Diphtheria Titer test is also included in the Tdap Panel along with Tetanus and Pertussis.

Turnaround time for this test is typically 2-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


The Diphtheria Titer test has no special requirements.
