What does a low result mean?
A slightly lower level occurs with low-selenium soils or limited consumption of seafood and Brazil nuts.
What does a high result mean?
A high reading is almost invariably linked to recent dietary supplementation.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Would eating 2 to 3 Brazil nuts a day easily optimize my selenium status?
- Does this align consistently with my thyroid function tests?
- Is an annual checkup adequate?
Do you have a full blood test report?
