What does a low result mean?
A low or undetectable level is standard, confirming the absence of prominent thyroid autoimmune traits.
What does a high result mean?
A positive finding is very common (found in up to 15% of healthy people) and simply advises checking TSH once a year.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this antibody presence simply call for an annual routine TSH check?
- Is my active thyroid function completely normal today?
- Would a baseline thyroid ultrasound offer helpful structural reassurance?
