Thyroid hormone blood test..

[pumpkinhead]

So my wife and I decided to get our thyroid checked, as we felt our metabolisms have slowed a bit. Years ago we used to do experiments with our rats and How t3 Effected them... so we just wanted to make sure as researchers our body did not accidently absorb any thru our skin and we were completely normal....

Can someone explain this result to me:

Her TSH level: 1.64
My TSH level: 1.28

With this result you would assume we are HYPER thyroid, but it sure doesnt feel like it. Would this result be from our experiements in the past and our body still trying to slow down the amount of thyroid that could have been potentially absorbed into our system from a synthetic outside source?

normal range for TSH is .5 - 5.0. The lower the number indicates less stimulating hormone, as the body is saying their is TOO much T3/T4 in the blood and trying to get the thyroid gland to produce Less. I can't figure out why both our bodies would be telling our natural thyroid hormone to SLOW down. I wish he would have ran a free t3 free t4 test, but he didn't. When I asked him to test the thyroid I expected him to run a full panel, not just TSH.

According to my endo, a better range for tsh is .5-3.0
You might be just fine. Did you test thyroid antibodies? Maybe get the other thyroid test as well to determine overall blood levels.

It changes from lab to lab but generally 0.5 to 4.5 is considered a normal range. That is a wide range. But having a TSH in the 1s is basically normal. People that have severe hyperthyrdoidism come in with TSH of 0.1 which means their T4 T3 is so high that no TSH is basically being produced. You obviously can make a better assessment with a Free t4 and t3 but i am 99% sure even with those numbers they will be within normal range looking at your TSH.

Thanks for the reply guys.... Had my doc run a free t3 / t4 test as well... nurse called me with yesterday to tell me they both fell in the normal range. I hate how the call and just say your "Normal".. I guess the general population just cares about Normal, rather then hearing exact numbers. Too lazy to call her back, but knowing my FSH is 1.2ish and t3 and t4 are "normal"....looks like we are good.

For thoose of you who express concerns with doing experiments with rats for more then 8 weeks, no worries.
