Beaumont Laboratory

Total Triiodothyronine (T3)

T3, Total Triiodothyronine

Specimen Collection Criteria

Effective March 26, 2006 the Total Triiodothyronine (T3) assay will no longer be performed by Beaumont Laboratory. The literature suggests that FreeT3 is the preferred test since it more correctly predicts the thyroid status in the presence of Thyroid Binding Protein abnormalities.
