What does a low result mean?
A very low or undetectable level is expected and reassuring following thyroidectomy, confirming complete tissue clearance.
What does a high result mean?
A moderate elevation is common and benign with simple goiters, benign colloid nodules, or mild thyroid inflammation.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this align with known benign thyroid nodules?
- Does companion anti-thyroglobulin antibody testing confirm measurement reliability?
- Is routine ultrasound follow-up appropriate?
