Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
0.4 – 2.3 g/L

What does a low result mean?
A modest count is very common and natural when no recent microbial encounter has taken place.
What does a high result mean?
A mild elevation is the expected hallmark of a recent, successful primary immune defense.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this reflect recent contact with a common seasonal virus?
- Have long-term IgG antibodies assumed primary coverage?
- Is a follow-up test planned later?
Do you have a full blood test report?
