Frequently Asked Questions
What does the Diphtheria IgG test measure?
It quantifies IgG antibodies against the diphtheria toxin in serum, indicating prior exposure or vaccination immunity status.
Is fasting required for this test?
No, fasting is not required. Serum can be collected at any time of day.
What level is considered protective against diphtheria?
An IgG level of ≥0.1 IU/mL is generally considered protective. Levels below this indicate susceptibility and may warrant booster vaccination.
Who should get this test done?
Adults seeking travel documentation, healthcare workers, individuals with unknown vaccination history, and during outbreak investigations in communities.
How long does it take to get results?
Reports are typically available within 24–48 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
Can childhood vaccination affect results?
Yes, prior DPT vaccination typically produces detectable IgG levels. Immunity wanes over time, so adult booster doses may be needed to maintain protection.
