View Full Version : help understanding hypo lab results

Hi all,
I would love it if someone could provide educated feedback on my most recent lab results. I was diagnosed hypo with hashimotos about 6 years ago and took 100 mcg of synthroid, which was a steady increase from the original 50mcg. Anyway, I just got switched to armour (60mg daily) and am waiting to start feeling better. My problem is that my TSH level (I haven't paid much attention to the other numbers) always seems to go up every 6 months and I need a medication adjustment. I'm hoping it will level out with the armour and I'll feel better. I have all the classic symptoms. Anyway,wondering if these results look pretty good (except for the higher TSH which I try to keep under 2.0) or if you can tell what might be going on, i.e. what I should pay attention to and watch for or any additional tests I should have. My TSH has been up to 7 in the past so this doesn't seem that bad, but I feel pretty terrible...

TSH 3.52 ("normal" range at lab .40 - 4.50 ha ha)
Thyroxine -Free 0.9 (normal range 0.8 - 1.8)
T4 Total 6.1 (normal 4.5 - 12.5)
T3 Uptake 33.1 (normal 22 - 35

Those are all the tests I had done. I had the antibody test 5 years ago and not since then. Please let me know your thoughts as I'm realizing now that this condition requires us to be very self educated! I'm working on it.

Hi Katie. Just so you know, now that you are on Armour the TSH is not a meaningful measure of your thyroid function. The T3 in Armour will 'most likely' suppress your tsh to a level below the normal range - think levels like .01 - .04. Hopefully your doctor knows this and doesn't freak out if it becomes below normal. The most important labs you will need done to monitor your status going forward is of course how you're feeling as well as FT4 and FT3. It looks like your last labs didn't include a FT3 measurement which feels a bit weird since usually it is the T3 level doctors are trying to raise when using Armour. Without an understanding of where you're at on this, it's hard to say if you truly need T3 supplementation. Most people benefit from T3 so it may not be an issue for you but you will need to monitor your FT3 level going forward.

Hope this helps.

Katie..................When you get labs done always get TSH, FT4, and FT3. Getting the total T3 and T4 are useless. Your are still very hypo, but drs. usually like to increase the Armour slowly. You want the get the free's up to70% - 80% of range and balanced. Sometimes to balance them, you may have to add a little "t4 only". Have you had an ultrasound to see if you have any nodules?

Hope you get to feeling better soon.
