From: Staci on 26 Nov 2005 23:11 I just received my thyroid workup here are the new numbers: t4 free 1.21 range 0.61-1.76 tsh 1.452 0.35-5.5 t4 -11.6 4.5-12.0 t3 uptake 18% 24-39 free thoxine index 2.1 1.2-4.9 t3-272 85-205 triiodothyronine free serum-3.2 2.3-4.2 Can anyone tell me what they indicate?

Everything else is in range. Normally this would not be cause for concern in and of itself. How are you feeling? Are you on thyroid hormone replacment or antithyroid therapy?
From: Staci on 28 Nov 2005 17:51 I have hyper feelings. I have a fast heart rate and anxiety. However, I am told since my TSH is in normal range to wait and see. My t3 has jumped by 40 in the last 8 weeks. I am not on any antithyroid or hormone replacement. However, I just don't feel well. My resting pulse is around 90. I hate the wait and see approach.

Find another doctor, there is no need to wait when symptoms, marginal test results and rapid major changes have occurred recently and in a short time frame. A low dose of antithyroid drugs or beta blockers or both is the likely prescription. But get a doctor who isn't going to wait until you drop from a heart attack. <gack!> Best wishes Kevin

The key result is the low T3-uptake. That is an indirect measure of the amount of binding proteins. A *low* result for the test as expressed by this lab means that you have *high* levels of binding proteins. Yes, upside down. But high levels of binding proteins means that the total levels of either T3 or T4 must be higher than normal so that your free-T3 and free-T4 levels will be normal. The free-hormone levels are what your body actually uses. The free-thyroxine index is calculated from the total-T4 and the T3-uptake (11.6 x 0.18 = 2.1); it is essentially identical to getting a free-T4 result....but you also got those measured directly. Now then, the problem is: what might be causing the high levels of binding proteins? The easy one to rule out would be drugs you might be taking, including esp estrogen (there are others, of course, including Tamoxifen and heroin(!!), but don't ignore "supplements" as they are drugs, too....so how about soy or broccoli that are high in isoflavones that act like estrogens?). The next easiest would probably be liver damage; since the doc probably did a "complete blood panel" of liver/kidney/CBC tests as start or in addition to testing the thyroid; if you don't have liver enzyme test results, now would be a good time to get them. Something more difficult to rule out would be that you inherited having high levels of binding proteins; anyone else in your family have the same problem? And lastly, this is the most likely cause now, that you have high levels of estrogen in your body from some other problem, usually PCOS for women. So, estrogen is the "usual suspect."

He said I'd gone too long without having anything expensive. |
