Drugs producing increased TBG include clofibrate, lithium, methimazole, phenothiazines, and propylthiouracil. Decreased T3 uptake may occur in hypothyroidism Normal Adult Range: 10 - 26 mcg/dL back to top FREE T4 INDEX (T7) Normal Adult Range: 0.8 1.8 ng/dL back to top TRIIODOTHYRONINE - T3 TOTAL Normal Adult Range: ng/dL back to top THYROID -STIMULATING HORMONE.Because I have a fantastic doc who knows his stuff, I take a combination of Cytomel (T3) and Armour (a natural thyroid medication made from pig thyroid which has all of the thyroid hormones in it).
I will look through my files and try to make sense of your numbers, but I'm not up on the exact ratios and you are missing quite a few numbers. Give me a couple days, as we're getting ready to go out to the in-laws today.T3 Uptake does not measure the level of T3 or T4 in serum. Increased T3 uptake (decreased TBG) in euthyroid patients is seen in chronic liver disease, protein-losing states, and with use of the following drugs: androgens, barbiturates, bishydroxycourmarin, chlorpropamide, corticosteroids, danazol, d-thyroxine, penicillin, phenylbutazone, valproic acid, and androgens.
When my doctor retired, he put me in good hands with another doctor he trained, who combines a lot of natural medicine (and good diets) with his healing practice. My new doctor is now on the list.Decreased levels are found in hypothyroidism, normal pregnancy, and hyperestrogenis status. This test measures the amount of thyroxine-binding globulin (TBG) in the patient's serum. When TBG is increased, T3 uptake is decreased, and vice versa.
Drugs producing increased TBG include clofibrate, lithium, methimazole, phenothiazines, and propylthiouracil. Decreased T3 uptake may occur in hypothyroidism This is what my research pointed to as well. I've heard a lot about hypothyroidism, but not much about hyperthyroidism.Low levels can be found in Cretinism, hypothyroidism, cirrhosis, malnutrition, and chronic thyroiditis. This is a measurement of the total thyroxine in the serum, including both the physiologically active (free) form, and the inactive form bound to thyroxine-binding globulin (TBG).
I think without the Reverse T3 or Reverse T4, we won't really know, because those are supposed to be in a specific ratio. He wrote that ratio on one of my lab sheets - I will have to look for it, as I have several years worth of labs.Thanks! MoonDansyr Sun, Jul-08-12, 09:48 Freckles, I will have to dig out my files and look at these numbers. I am here to tell you that your "TSH" is considered "in range" by 99.9 of doctors; sadly, that's what many of them go by and it doesn't tell the whole story.
If you have a health question, please read about. Signs and Symptoms before our conversation.

My problem is that I don't convert my T4 to T3, so I have to take T3. If I had a doctor that tried that with me, I'd be spinning my wheels and they would consider me a nut job because they'd tell my my TSH was in range, therefore it must all be in.View Full Version : What do these results mean?

Thu, Jul-12-12, 11:05 Your T4 looks a tad less than optimal. TSH is a bit highish, which means your body might like more thyroid hormone. Thyroxine-Binding Globulation (T3-UPTAKE ) - Increased levels are found in hyperthyroidism, severe liver disease, metastatic malignancy, and pulmonary insufficiency.
Drugs producing increased TBG include clofibrate, lithium, methimazole, phenothiazines, and propylthiouracil. Decreased T3 uptake may occur in hypothyroidism freckles Fri, Jul-13-12, 14:49 Your T4 looks a tad less than optimal. TSH is a bit highish, which means your body might like more thyroid hormone.All of the numbers have to be in the proper ratio, so just because they are all within range, it doesn't mean they are where they should be with each other.
But I think pharmaceutical companies have a hand in causing the current problems. Also, I found my first doctor (who retired his practice to return to education in hopes of spreading knowledge) through Top Doctors (m/m) from deep within the m thyroid disease site.A change in the level of TSH in the blood may signify a malfunctioning of the thyroid gland. THYROXINE (T4) - Increased levels are found in hyperthyroidism, acute thyroiditis, and hepatitis.
I will also tell you that I have symptoms when my TSH is at that number. Currently, mine is below a 1. My doctor allowed me to adjust my meds myself, finding the right dose that made all of my symptoms go away.Most search results about this test indicated that it was basically useless and outdated. Plus when considering all usual symptoms of hyperthyroidism, I had none of them (alas, particularly not weight loss I choose not to worry about it.
Or do I just need to wait for the proper tests? T3 uptake 37 high Thyroxine (T4) 5.7 (4.5 - 12.0) Free thyroxine index, ng/dL 2.1 TSH, mIU/L 2.95 (no range given) I had MANY more tests run, so if there are any others that would be helpful let me know and I will post.It is increased in hyperthyroidism and in euthyroid states characterized by increased TBG. Occasionally, hyperthyroidism will not be manifested by elevation of T4 (free or total but only by elevation of T3 (triiodothyronine).
Doctors like him are 1 in a million. So, many doctors go mostly by the TSH, and won't do anything until you are DEFINITELY out of range. Then, they often will only prescribe Synthroid, which is synthetic T4.What I did do was slightly increase non-starchy vegetable carbs, and supplement with iodine and selenium (realized had basically no sources of iodine in my diet). Mild symptoms of hypothyroidism seem to have improved, so a symptom, rather than test approach worked.
When T4 and T3 are too high, TSH secretion decreases, when T4 and T3 are low, TSH secretion increases. Normal Adult Range: miliIU/L back to top.

I highly recommend going to m Thyroid Disease (m and looking up everything you can find by Mary Shomon. Thyroid disease is horribly taught in medical schools (even with endocrinologists). It shouldn't be that way, as there ARE doctors (few and far between) who do understand it.While I was nervous to switch, at first, I am beyond more than happy with this new doctor and am finding that I may even like him better, which I never thought possible.
COMMON LAB VALUES IN THE THYROID Click here to contact me with questions about your laboratory results - I do not volley e-mails back and forth because it is just too time consuming to keep track of who is responding to what e-mail.I have been looking for a doc who will know to do the right tests. Think I finally found one. In the meantime, my current hematologist had these tests done. Can I glean any information from them?
T4 is decreased in hypothyroidism and in euthyroid states characterized by decreased TBG. A separate test for "free T4" is available, but it is not usually necessary for the diagnosis of functional thyroid disorders Normal Adult Range: 4 - 11 mcg/dL back to top Thyroxine-Binding Globulation (T3-UPTAKE ) - Increased levels are found in hyperthyroidism.I'm not even on any meds at this point. I am still in the process of finding a doc who will do the right tests. :rolleyes: Thyroxine-Binding Globulation (T3-UPTAKE ) - Increased levels are found in hyperthyroidism, severe liver disease, metastatic malignancy, and pulmonary insufficiency.
Interesting that you posted this. I've been listening to The Real Foods Summit and the role of selenium and iodine on thyroid has been mentioned. I was going to do further research about it, actually, since I also don't get much of either in my diet.Forget starvation and fad diets - join the healthy eating crowd!
