TSI (Thyroid stimulating Immunoglobulin)

The TSI test has replaced and updated the TRab test. Please note some labs are still doing the TRab. This test will be provided in those cases. 
Thyroid stimulating immunoglobulin (TSI): A form of immunoglobulin G (IgG) that can bind to thyrotropin (TSH) receptors on the thyroid gland. TSIs mimic the action of TSH, causing excess secretion of thyroxine and triiodothyronine. The TSI level is abnormally high in persons with hyperthyroidism due to Graves' disease.

Reverse T3

 RT3 is a metabolite of T4 (thyroxine). Typically, when T4 loses an atom of iodine—a process known as monodeiodination, or T4 to T3 conversion—it becomes triiodothyronine (T3), the active thyroid hormone. But in some cases, the body conserves energy by converting the T4 instead into RT3, an inactive form of T3 that is incapable of delivering oxygen and energy to the cells, as T3 does.

ETA for results: usually 24-48 hours. the RT3 can be up to 2 weeks. Fasting not required.
