What does a low result mean?
A slightly lower level can be constitutional or medication-related, frequently without causing increased susceptibility.
What does a high result mean?
A mildly increased concentration illustrates active immune memory from previous challenges overcome successfully.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this IgG level confirm robust long-term immune protection?
- Could this reflect past minor infections resolved long ago?
- Is a follow-up assessment indicated?
