Test Results - Opinions Please


I have recently switched from T4 only (for 35+ years) to a T4/T3 combo - I've been on the new combo for 6 weeks and have received the test results below. I feel much better, like I'm on the right track - if not 100% perfect (though it's been awhile since I've known what that might feel like).

I would appreciate any feedback on what you see in these results to double confirm I am on the right track:

Dosage: T4 (100 mg) / T3 (16 mg)
TSH: .006  (0.450-4.5)
T4: 7.1  (4.5-12.0)
T3: 115 (71-180)
Free T4: 1.52   (0.82-1.77)
Free T3: 3.3  (2.0-4.4)

Thank you!

At this point I think I would deal with the least amount of change possible and just look to increase the Free T3 level.  Yes your Vitamin D is lower than optimal at 55-60.  I would not assume iron is okay just from that one test.  Better to test for ferritin, which should be about 70 minimum.

Thank you for your quick response. I'm encouraged by your feedback both with regards to my progress and with my understanding of things. I was thinking a skosh more T3 could continue to improve things. In your opinion, is the T4 too high? Wondering if it would serve to lower that... Thanks, too, for the info on the supplements - My iron is good at 83, Vit D is a bit low at 38.1 and my B12 is oddly high at 1312(?). Appreciate the support and your sharing of knowledge!

Glad to hear that you are feeling some better.  Your current results show that your Free T4 is at about 74% of its range, which is above minimum recommended of middle of the range.  So plenty there.  Your Free T3 is at only 54% of its range, which is not high enough if you still have hypo symptoms.  So you can ask about raising your T3 dosage and see how that affect your symptoms.  

Since hypo patients are so frequently low in the ranges for Vitamin D, B12 and ferritin, and those can adversely affect metabolism of thyroid hormone as well as cause symptoms that sometimes mimic hypothyroidism,  I suggest tests for those and supplements as needed to optimize.  D should be about 55-60, B12 in the upper end of its range, and ferritin should be about 70 minimum.
