A panel is just a group of tests routinely run at the same time. For MOST doctors, a thyroid panel includes these tests:
* T4 Total (aka Thyroxine or simply T4)
* T3 Uptake (aka T Uptake--not a T3 test at all, but a measure of thyroid hormone binding proteins used to calculate the next value)
* Free Thyroxine Index (aka FTI, Calculated Free T4 or T7--this is a CALCULATED value and as such is not very accurate compared to a direct measure of Free T4)
The above panel is outdated and not nearly as informative as the next list. Smarter docs will run these tests instead:
- * TSH
* Free T4 (aka Free Thyroxine or T4, Free)
* Free T3 (aka Free Triiodothyronine or Triiodothyronine, Free)
If your doctor feels that you have unusual thyroid binding protein levels, he may add Total T4 as well as the Free T4 to compare those values.
If a doctor suspects Hashimoto's or Graves, they might also add antibodies testing to the panel, but this is an exception to the rule. If you have a doctor that runs the tests on the second list and includes antibodies as well, consider yourself lucky.
