TSH levels high but T3 and T4 normal, am I hypo?

I went in to the Dr. because I was having GI problems and I was tired all the time. I mentioned that I also get cold very easily in comparison to others. He said it sounded like IBS.
Tests come back and my TSH is a 12 (twelve). A week later I take T3 and T4 tests. They start me on 50mcg levothyroxine after the test.
Four days after starting the pills I am told to stop taking them because my T3 and T4 levels are normal and that my first TSH test must have been a lab error.
I didn't even know what hypothyroidism was when this all started, but now I've found out that my mother (whom I don't speak with regularly) has had hypo since she was 40. I'm 22 now, am I hypo, are the tests wrong, should I see a specialist?
Thank you for any suggestions, I'm really confused.

Forget the TSH result.  TSH is a pituitary hormone that is affected by so many things that at best it is only an indicator to be considered along with more important indicators such as symptoms and also levels of the biologically active thyroid hormones, Free T4 and Free T3.   When already taking thyroid hormone TSH is basically a wasted test, since it is so frequently suppressed to the low end of the range, or below when thyroid med dosage is adequate.  Note the words of a good thyroid doctor, " in tests done about 24 to 28 hrs after their last daily dose, most people on adequate NDT therapy have a suppressed TSH. They usually have FT4 levels that
are 1 to 1.3ng/dL, and free T3 levels that are rather high in the range or even slightly above the range."

Which raises the question whether you took your med before the blood draw for those tests?  Also do you split the dose into halves for morning and early afternoon doses?

Please post the actual cortisol test results and ranges shown on the lab report.

I have been treated for Thyroid issues for the past 3 or 4 years, starting out on Synthroid.  I recently switched to a desiccated thyroid and my results are as follows:

TSH 3.31 - lab range 0.3-4.00
Free T3 5.8 - lab range 3.5-6.5
Free T4 15 - lab range 9-23

I have also had the 24 hour Saliva test done and found that my cortisol levels are less than 0.01.  My Naturopath path told me I should feel like a 90 year old with those cortisol levels and quite frankly I am pretty close to feeling that way!  I have also had both my antibodies tested and they both came back within range so he ruled out Hashi's.

My question is - since my Free T3 & T4 appear to be pretty normal, but my TSH is still higher than optimal - is my issue my Thyroid right now or do I need to focus on getting my Cortisol up and in turn that will fix my TSH levels?  

Thanks!

What are the reference ranges for your T3 and T4?  Reference ranges vary from lab to lab and have to come from your own report.  Also, can you tell us if those are Free T3 and Free T4 or is they are Total T3 and Total T4? Free T3 and Free T4 are the most important, while Total T3 and Total T4 are considered obsolete and not real useful.

Your doctor has tested total T3 and total T4.  Next time, request the FREE T3 and FREE T4 tests; they tell you the amount of hormone actually available for your body to use.

Both your FT3 and FT4 are low of the midpoint or above that they should be.  So, it would seem that a meds increase is in order.  What are you currently taking?

How do you feel?  Do you still have hypo symptoms?
