TSH T4 and T3 results. Need help interpreting them.

I received my test results via email and haven't spoken to my dr as it's the weekend. I am trying to work out what my results mean but I'm having trouble understanding. I hate having to wait and worry the whole weekend before I can speak to my dr.

I'm a 28 year old female. I have symptoms of hypothyroidism fatigue, dry skin, cold sensitivity, depression, anxiety, my hair falls out. I could go on.

My results are as follows

TSH - 2.37 - std range 0.27-4.20
T4 FREE - 1.34 - std range 0.93-1.70
T3 FREE - 3.5 - std range 2.5-4.3

Thank you in advance

Without knowledge of your symptoms, I would not be concerned with those test results; however, in view of those symptoms, I think that you need to get some further testing done.  I say that because hypothyroidism is caused by inadequate supply of, or response to, thyroid hormones at the cellular level throughout the body.  This means that your thyroid status is affected by many variables beyond just serum thyroid levels.  Inadequate Vitamin D and ferritin can adversely affect metabolism of thyroid hormone.  Cortisol is an antagonist of thyroid hormone, so high levels of cortisol can cause hypothyroid symptoms, even with what appears to be adequate serum thyroid hormone.  Low levels of B12 can also cause severe fatigue.  Also, when T4 is being converted to T3 some Reverse T3 is also produced.  If excess Reverse T3 is produced, and the ratio of Free T3 to Reverse T3 becomes too low, that can cause hypo symptoms.

So, I suggest that you should ask the doctor to test for Free T3  (again) and Reverse T3, along with Vitamin D, B12 and ferritin.  The best test for cortisol is the 4 panel diurnal saliva cortisol tests, but doctors typically refuse to do that.  Instead they only run serum cortisol tests, which is harder to interpret due to the wide variation in cortisol level through the day.  

If you can get those done and post results and ranges, we will be glad to help interpret and advise further.
