Diphtheria IgG Antibody, serum

Diphtheria IgG Antibody, Serum

Test Overview:
The Diphtheria IgG Antibody test measures the level of IgG antibodies against Corynebacterium diphtheriae in the blood. These antibodies are produced following vaccination or previous exposure and can help assess immunity against diphtheria.

Why is this test done?

• To assess immunity against diphtheria.
• To evaluate the antibody response after vaccination.
• To investigate inadequate or uncertain vaccination history.
• To support assessment of immune response in selected clinical situations.

Sample Required:
Serum

Test Method:
Immunoassay / quantitative antibody testing, depending on the laboratory platform.

Result Interpretation:

• Protective antibody

  Test Method:
  Immunoassay / quantitative antibody testing, depending on the laboratory platform.

  Result Interpretation:

  • Protective antibody level: Suggests immunity against diphtheria.
  • Low or non-protective level: May indicate insufficient immunity and the need for clinical evaluation of vaccination status.

  Important: Results should be interpreted along with vaccination history and clinical findings. A positive IgG result generally indicates antibody-mediated immunity but does not necessarily indicate current infection.
