Episode - What Are Thyroid Stimulating Immunoglobulins?


What Are Thyroid Stimulating Immunoglobulins?

Thyroid stimulating immunoglobulins (TSI) are a type of thyrotropin receptor antibody commonly associated with Graves’ Disease.

Even though most people with hyperthyroidism would benefit from getting their TSI tested, many endocrinologists ignore this test altogether or test only once per year.

Today I’m sharing what thyroid stimulating immunoglobulins are and why monitoring your levels is essential.


During this episode, you’ll learn:

  • What are thyroid stimulating immunoglobulins (TSI)?
  • The association between elevated TSI levels and Graves’ Disease
  • Why you can’t compare levels from different labs
  • Optimal TSI reference ranges
  • What you can do to lower thyroid antibody levels
  • The relationship between TSI and thyroid eye disease
  • How you can decrease TSI


As always, I hope you found this episode valuable, and I look forward to catching you in the next episode!
