The three main types of thyroid antibodies are thyroid peroxidase (TPO) antibodies, thyroglobulin antibodies, and thyroid stimulating immunoglobulins (TSI). Although it’s rarely mentioned, there is a fourth type of antibody known as TSH-binding inhibitor immunoglobulins (TBII). Today, I’m sharing what the research tells us about the role of TBII and whether it’s worth testing as part of your thyroid panel.

In this episode, you’ll learn about:
- Different types of thyroid antibodies
- Controversy surrounding TSH-binding inhibitor immunoglobulins
- Whether you should test for TSH-binding inhibitor immunoglobulins
- Interpreting thyroid antibody test results in context
- My approach to thyroid antibody testing

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