Episode notes
Test Beyond Just TSH
- Get at least TSH, free T4 and free T3 when screening thyroid function; T3 is the active hormone.
- If symptoms persist, add reverse T3 and thyroid antibodies to detect conversion issues or autoimmunity.
Autoimmunity Often Precedes Dysfunction
- Thyroid autoantibodies often appear years before overt dysfunction, especially in Hashimoto's.
- Testing antibodies early can reveal a silent autoimmune phase and allow earlier intervention.
Which Thyroid Antibodies To Check
- Test TPO, thyroglobulin, and TSH receptor (TSI) antibodies when evaluating thyroid autoimmunity.
- Recognize that people can have multiple antibodies and mixed Hashimoto's/Graves presentations.
