Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 Hi Jae, Try to Thyroid Manager website, www.thyroidmanager.org/thyroidbook.htm It's important to have an FT3 at the time of diagnosis to see if you have T3 thyrotoxicosis. Your endo should know this. If FT3 is high and FT4 is normal then you would need to monitor your ATD therapy with FT3 levels. If both FT4 and FT3 are high, then you wouldn't need an FT3 test every time you have labs. TSH, though, should never be used as the sole test for monitoring TSH. Your endo can find this in Werner & Ingbar's The Thyroid and in numerous articles. A Pub Med search on Brokken will link you to his articles, which explain the mechanism here. Take care, Elaine Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 Does anyone have any links or references at all in professional journals that discuss the role of monitoring and/or replacing FT3 and FT4 in ATD therapy and discuss the need to test FT3? My doc says that most of the information on these boards is the equivalent of superstition, utterly without scientific foundation. I'M NOT SAYING I AGREE. I think there is a lot of experience represented here. I'm just asking if anyone has any professional journal articles. jae Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 A thousand thanks! One thing, though. I did look on the list files for this and could not find the answer. The tests you all talk about are called different things on my endo's test form or are not even listed at all. You all talk about FT3 and FT4 and here are tests I have listed: -------------- Thyroxine Thyroid uptake (this is a lab test not the radioactive iodine test) Free Thyroxine index TSH 3rd generation T4 (Free) TSH -------------- I see nothing that says T3 at all. Are any of these T3? Also are any of these the " old tests " or the bad tests? What are the lab names or words that the doctor would write to get the FT3 test you all say is important? I will write it on the form myself. What is the name and/or abbreviation of the antibody test? My endo says this test is meaningless. Sigh. But I think I had it.
