About Our Diphtheria Immunity Test

Fasting Instructions:

This blood test is used to assess the amount of antibody response to the diphtheria toxoid vaccine. This test is used to help determine if an individual has immunity to diphtheria (caused by Corynebacterium diphtheriae) following immunization.

Determination of vaccine response should be performed at least three weeks following immunization.

Diphtheria is a serious infection of the nose and throat that's easily preventable via vaccine. It is spread from person-to-person through coughing and sneezing and can be fatal if not treated.
