Thyroid Levels

I've been promising to post my thyroid test results for about 8 months now. Clearly I've been lazy about it, but for those of you who are into this sort of thing, here they are, finally. I'm including the test names exactly as they are written on the lab results, with the normal ranges in parentheses and abnormal results bolded:

Sept. 2001 (family physician, part of bloodwork for a routine physical) - T3 uptake 35.8% (23.4-42.7); Thyroxine (T4) 7.9 (4.5-12.5); T7 Index 2.8 (1.2-4.3); TSH 0.19 low (0.40-5.20)

Sept. 2002 (family physician, part of bloodwork for a routine physical) - TSH High Sensitivity 1.10 (0.40-5.20); Free T4, Non Dialysis 1.0 (0.8-1.9)

March 2003 (ob/gyn, for irregular cycles after starting TTC, got diagnosis of PCOS at this time) - TSH High Sensitivity 0.51 (0.40-5.20)

April 2005 (endocrinologist, regarding PCOS while on a break from TTC) - TSH High Sensitivity 1.18 (0.45-4.50); T4 Free, Non-Dialysis 1.5 (0.8-1.9)

October 2005 (family physician, part of bloodwork for a routine physical) - TSH High Sensitivity 0.41 low (0.45-4.50); T4 Free Non-Dialysis 1.6 (0.8-1.9)

July 2008 (RE, one-day workup) - TSH 3rd Generation 2.29 (0.40-4.50); T4 Free 1.1 (0.8-1.8)

Sept. 2008 (different familiy physician, part of bloodwork because she thought something was up with my thyroid) - TSH 0.092 low (0.45-4.50); Thyroxine T4 8.3 (4.5-12); Thyroxine T4 Free Direct S 1.30 (0.61-1.76); Triiodothyronine T3 188 (85-205); Triiodothyronine Free Serum 3.3 (2.3-4.2)

Oct. 2008 (endocrinologist) - TSH 3.19 high (0.30 - 3.00); Free T3 3.8 (1.5-4.1); Free T4 1.28 (0.80-2.00); Total T3 76.8 (65.0-185.0); T3 Uptake 32.3% (25.0-40.0); Total T4 6.3 (4.5-12.5); FTI 2.03 (1.13-5.00); Anti-TG Abs 69.2 high (0.0-40.0); Anti-TPO Abs <10.0 (0.0-35.0); TRab <1.0 (0.0-40.0)

Nov. 2008 (endocrinologist) - TSH 4.95 high (0.30 - 3.00); Free T3 5.7 high (1.5-4.1); Total T3 225 high (65.0-185.0); T3 Uptake 23.7% low (25.0-40.0); Total T4 10.5 (4.5-12.5); FTI 2.49 (1.13-5.00)

I'm no longer seeing the endocrinologist who did those last two rounds of bloodwork, because my company went with a new health insurance plan this year, and he isn't on it. I had an appointment about a month ago with a new endocrinologist, and I'm hopeful that she will be a good doctor to work with.

She was very patient and listened to my whole story. She was also encouraging about the baby thing, saying that "when" I get pregnant again, she wants to see me immediately and then will continue to monitor me every 6 weeks or so throughout the pregnancy. She and her husband tried for four years before they were able to conceive, and she just had her baby this year, so she really relates to us wanting to get (and stay!) pregnant.

She said she thinks I have a rare form of thyroiditis called Hashi-something-something-thyroiditis. (Not Hashimoto's.) She said a virus or other triggers may be causing my immune system to attack my thyroid occasionally, which leads my thyroid to dump all the hormone it's holding, initially causing my TSH to drop and then rise slightly abnormally high before settling down again. That kind of makes sense, because when I had the really low TSH level in September, the blood for that test was drawn about two weeks after I had a really bad cold.

My next step is to go back to her in August. I'll get the results of the bloodwork I did last month at that time; I'm guessing it was normal based on how I was feeling. She also wants me to repeat the bloodwork in the meantime if I think I'm feeling significantly hyper or hypo, but so far that hasn't been the case.

From there, she'll continue to monitor me every 6 weeks to 2 months until my bloodwork shows three consecutive normal levels. At that point, we'll look at doing a transfer, depending on how things are going with my dad and how I'm feeling about my weight and overall general health.

I've been wondering how you were doing and how things were with your Dad. I'm glad you're working with someone that understands where you are and where you're trying to get to. good luck with everything.

It sounds like this Dr is on the ball and understanding of the IF issues as well. I hope this is the gameplan that does the trick!

This is very interesting. I've been seeing my TSH go down over the last couple of years, below 1.0. I think this last time it was about 0.6. My Free T3 tends to be high. I had an ultrasound of my thyroid done last March, and they didn't see anything weird. I don't know if I have any kind of auto-immune thing going on. I hope not. Your results make me wonder...

I hope you find some sort of answers for all this!
