Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 It would be good to see the rest of the thyroid tests together with the reference ranges and the exact name of each test. T3 uptake is an obsolete test which does not measure T3. It measures thyroid binding globulins and is used in a calculation together with the semi-accurate Total T4 to yield the Free Thyroxine Index, also called T7, another obsolete test which estimates free T4 levels. I am not sure what the other tests you have listed may mean. henningc50 wrote: I got a copy of my comprensive workup from the doctor. I did not feel good at the time this testing was done.

Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 Not a problem. I can't provide you with the T3 information because they don't test for it. I can speak to my doctor next time I see her, but for now this is what I have to work with. TSH .5(.3-5.1) Free T4 1.86 (.73-1.95) T3 uptake 39.7 (20.-38.5) If the T3 uptake measure thyroid binding globulins, is a high number like mine saying that the binding is below normal or above?

Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 At the time this test was taken, I was showing most of the normal hypothyroid problems, brain fog, achey, tired, cold etc. My old doctor had agreed to raise my synthroid. The new meds arrived a week after this test was taken. The increase took away all my hypo symptoms. I just got blood drawn by my new doctor today. She cautioned me that she was concerned about the numbers and the suppressed TSH. She also decided to run antibodies to see if I have hashi or any other autoimmune activity. Until I looked at these lab results after leaving the doctor's office, I had not remembered that 20 years ago, a doctor told me that 10% of my thryoid output was defective. Now I wonder if this is what the T3 uptake number is saying? And this is why I seem to be at the edge of all the ranges. I don't see ferritin tested on this lab result. Why should I have it tested?

Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 Ferritin is your iron stores..you can have several of the hypo symptoms and the iron stores that are low. It can be common with hypo people. If your new doctors is looking at the numbers that closely and not your symptoms, I'd run. If she is going to rule your meds by TSH that is not good. My doctor does look but allows me to go up if I still have hypo symptoms and NO hyper symptoms. I no nothing about the T3 uptake other than it is an outdated test.

Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 Well, she has agreed to keep me on this higher dose of synthroid, but I really get the feeling she thinks something else is going on. And frankly, so do I. Every 6 months or so, my dosage goes up. I had subacute thyroidis and I should not be experiencing a continual deterioration of thyroid output. Her concern about the TSH was that if it gets too low, it can encourage osteoporosis. Since I am post menopausal, it is something that needs to be watched carefully. This is only the second time I have seen her, so we are just getting to know each other. I was quite frightened of my previous doctor, so I am a bit hypersensitive at this point.

Guest guest Posted May 31, 2005 Report Share Posted May 31, 2005 The bigger concern about osteoporosis is staying hypo. You will lose more bone mass staying hypo. If by symptoms you are still hypo, she shouldn't worry about it. There is no study out there that shows a connection between suppressed TSH and osteoporosis.

Guest guest Posted June 2, 2005 Report Share Posted June 2, 2005 Remember: It is not the lack of TSH that has these effects on bone minerelization, it is the thyroid hormones themselves. TSH is NOT the thyroid hormones, T3 and T4 are. This is where doctors don't seem to know how to add. 1 + 0 does NOT equal 2. So the TSH is not stimulating the thyroid. So what? In what way does that mean that bones will be affected. Even when the TSH is a flat "0", if the thyroid hormones are low, it's still hypothyroid by any other name. You do not know whether or not you have autoimmune thyroid disease? Why has she not tested for this already? In Hashimoto's, the TSH should ALWAYS be suppressed, not just low. Doctor doesn't know her stuff at all! And guess who will suffer for it. Re: numbers Well, she has agreed to keep me on this higher dose of synthroid, but I really get the feeling she thinks something else is going on. And frankly, so do I. Every 6 months or so, my dosage goes up. I had subacute thyroidis and I should not be experiencing a continual deterioration of thyroid output.

Guest guest Posted June 2, 2005 Report Share Posted June 2, 2005 Why didn't my previous 2 doctors check for Hashi? I have seen her twice now and just this time told her I had not been checked. She was surprised. She immediately ordered the antibody test. I do think I recently read something on the TSH and osteoporosis. My efficient computer eliminated the link. wrote: Remember: It is not the lack of TSH that has these effects on bone minerelization, it is the thyroid hormones themselves.
