Wow, thank you! This is awesome information and way more advice than my doctors provided. I really appreciate you asking the ASCLS for me. I was wondering about iron overload/hemochromatosis myself, after some basic researching. My mother has a rare blood disorder, and I know that other blood disorders have run in my family, too. Hopefully my primary will re-do the test in a few months to just check up on things, though at present he just thinks I have "good nutrition". Which, to me, is somewhat comical, as he was just commenting a few weeks ago that most young women under-eat and that it was probably just poor eating habits causing my hypo symptoms. Haha.
I also had another question for you, if you had the time. How common is it that TSH consistently remains within normal range in hypothyroidism?
Bumping to see if anyone knows about higher iron levels...
Ferritin, Serum: 45 -- range 15-150.
Iron Bind Cap. (TIBC): 422 -- range 250-450.
Iron Saturation: 55% -- range 15-55%.
Iron, Serum: 232 H -- range 35-155.
UIBC: 190 -- range 150-375.
Thank you! I tried looking some info up, and I am even more confused than I was already. I was fully expecting LOW iron. Not high. I don't take any iron supplements. I do take Vitamin C, which I read can help absorption of iron from foods. But honestly, I don't eat that much iron rich foods. I also read that too much iron can suppress thyroid? I'm wondering now if maybe that is part of the problem.
Also, my doctor advised that I will stay on the 88mcg for now, to see how I respond. After 6 weeks, depending on how well I am making T3, we can "look into" a T3 supplementation and talk about upping the Synthroid. I also scheduled an appointment with a holistic/homeopathic ND, who apparently often prescribes T3 -- either synthetic or natural. So hopefully I am on my way. :)
Some of those results seem contradictory. I need to do some reading about them. Will get back to you.
Can you explain the importance of ferritin and the like in thyroid? I had my iron panel done. Surprised with the results. Any thoughts?

Interpretation of test results
Question:
Could someone please comment on these test results? Ferritin, Serum: 45 -- range 15-150. Iron Bind Cap. (TIBC): 422 -- range 250-450. Iron Saturation: 55% -- range 15-55%. Iron, Serum: 232 H -- range 35-155. UIBC: 190 -- range 150-375. [Lab Tests Online Question referred from: /understanding/analytes/ferritin/tab/faq]

Response:
Thank you for contacting the American Society for Clinical Laboratory Science (ASCLS). We are a team of laboratory professionals who volunteer our time and expertise to assist consumers in understanding laboratory tests and results. We try to answer questions within 72 hours, but due to the large volume, we occasionally need more time. An Iron Saturation of 55% is borderline high. All of your other values are normal. You did not give your age or gender which can have a bearing on interpretation of these test results. Also, iron studies should be done on a fasting early morning specimen and you should be off of any iron supplements for at least a week. If you complied with the above, then I would suggest having the tests repeated just to make sure that the saturation level is correct. If it stays the same (i.e. increased or borderline high), depending on your age and gender, you may want to consider some follow-up testing for the condition known as hemochromatosis, or at the very least, repeat the iron studies in six months to see if the % saturation is staying the same or increasing.
