Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
0 – 115 UI/mL
0 – 115 UI/mL
0 – 115 UI/mL
What does a low result mean?
A negative test confirms absence of significant autoimmune reactivity toward thyroglobulin.
What does a high result mean?
A moderate positive titer is common and harmless, often mirroring anti-TPO patterns to describe thyroid individuality.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this antibody finding have any practical impact while my TSH remains normal?
- Is a yearly routine TSH monitoring plan the standard approach?
- Would a baseline thyroid ultrasound offer helpful anatomical context?
Do you have a full blood test report?
