    Hi Sue – If your doc ordered a T3 test as part of your panel, the lab results will tell the full story. However, keep in mind that the majority of patients do just fine on T4 alone. As Karen noted, the time to think about T3 issues is if your levels are normal/stable after a period of time (the European Thyroid Association recommends 6 months) and you are taking the meds properly – but you still aren’t feeling well.
