... Thanks for your feedback. I've been reading some more and apparently they ran an outdated thyroid test. T3 uptake doesn't measure your level of T3 hormone at all. It just measures how much is "taken up" by the binding proteins. I'm going to try and get a fuller panel ran. ... (4 replies)
... All the tests came back normal and they were about in the middle of the normal range, except for the T uptake, which came back at 30, with the low level of the normal range being 31, i forget what the high normal level number was. What does the T uptake mean? ... (1 replies)
... Absolutely not. It's a miniscule dose, won't harm you, will help diagnose if you have a viral thyroiditis, hashis or graves depending upon the uptake level. ... (9 replies)
... I will have to check my results for my T4 level when I get home. I dont remember, but I do know it was within the normal range. I suppose I can just call my doc. ... (2 replies)
... The free version of hormone tests doesn't only apply to thyroid ones there's at least free testosterone and free insulin and I'm pretty sure both show the bodies level of it more accurately. I think you need to find a new thyroid doctor. How are you gonna convince him that he's been treating people wrong for years. ... (3 replies)
... the blood proteins would take up very little T3. Thus a low T3 uptake implies elevated T4 levels and vice versa. Thus the T3 Uptake test is actually an antiquated, inaccurate way to measure T4 levels. ... (3 replies)
... The T4 test you had is for measuring the total combined levels of bound and free hormone. The total T4 test is a poor indicator of thyroid status. T3 uptake has nothing whatever to do with your T3 level, or anything else, really. ... (1 replies)

... I went ahead and did the RAI Uptake (Nuclear Medicine Scan) & just got my report for a Thyroid Scan & Uptake today. It's a hyperfunctioning nodule & I had a normal thyroid uptake. Now I'm even more confused by all of this. I haven't gotten my new blood work back yet to compare ranges, will post those results as soon as I get them, though.
Any thoughts??? (6 replies)
... So, I just received the Ultrasound CD today...and what do you know? There was a typo error on the measurements in the Report printout...the nodule is actually 1cm x 7.6mm x 8.7mm.
I'm not going to go ahead with the Nuclear Medicine Scan (also called the RAI Uptake Scan). Endocrinologist said it wasn't necessary because my TSH levels are LOW and the nodule would probably... (6 replies)
... At some point, don't most Graves patients go off Tapazole and take radioactive iodine because of the toxicity of Tapazole? That's the main thing I'm worried about long-term.
Also, since you mentioned my TSH level -- when I got my very first blood test done after I first started experiencing hyperthyroidism symptoms, the TSH was the same value (<.006) back then as well. The... (14 replies)
... I'm sorry I didn't suggest antibody testing sooner.
It seemed you were paying out-of-pocket for these tests and I know they're expensive.
Throw in the fact that the first set of labs you posted were so very hypo, I didn't expect to hear about hyper symptoms.
My 20/20 hindsight tells me I should have asked about symptoms. Whatchagonna do with this cheap help? ;)

... Wow what great information! I couldn't have asked for more. Ironically, most of the symptoms I have are of hypERthyroidism. In fact, I suffer from all the major symptoms at a high level (not chronic, but they effect my life thoroughly). I am going in for a TPO test today (3 blood tests in one week, geezzz), so that might add some insight as well. If that comes back negative, I... (16 replies)
... Unfortunately, the T3 uptake and Free thyroxine index tests are outdated calculations and not even true measurements of hormone levels. ... (16 replies)

... Hey everyone, I was wondering if I could have some of you look at the numbers I have been given and help me better understand them. I had my daughter back in July 2010 and ever since then I've been having health issues which no doctor has been able to figure out. I feel awful all of the time. Well I found a NP who decided to draw some blood. The first thing she noticed is... (1 replies)
... My current T-4 level is 10.9 and T-Uptake is 30.2 and T-7 is 3.29. Of course, these were taken before he elected to take me off the every Sunday half extra pill of 137 mg Synthroid. (7 replies)
... Good to know... Hopefully, it will calm down with the meds. The Dr. just up'd the dose this week. The dr. mentioned possibly scanning my thyroid as it feels 'puffy'. And I was just reading some of the posts about iodine scans and thought it would not be a good idea for me as I react so badly to things. Ultrasound, if needed, sounds much safer. (7 replies)
