The normal levels for the T4 need to be 4-11.

TSH 05-25 uIUmL free T3 38-44 pgmL free T4 14-177 ngdL anti-TPO 00 IUmL and anti-TG 00 IUmL. T3 is more biologically active than T4. T4 Free 09-18 T3 Free 23-42 Ive been on Thyroid NP which I love for a little over 2 12 months now but still feel something is a bit off because i have a little lingering dizziness from time to time and.

We feel the Free T3 is the most clinically relevant test to assess optimal thyroid function. Reverse T3 – Reverse T3 is the anti-thyroid metabolite which competes for binding with T3. Based on the reference ranges given above for the normal reference range the following gives the optimal range that most thyroid patients report feeling their best at.

The normal range of TSH levels in adults is between 04 to 40 mIUL milli-international units per liter. Pregnancy can also increase total T3 levels. Reverse T3 at a ratio less than 101 RT3Free T3.

2 – 44 pmolL. Many factors influence T3 levels including age sex and some preexisting health conditions such as liver disease. Now lets figure out the math.

In low adrenal function the body temperature is low and unstable but TSH T3 and T4 are low. For this reason it would seem intuitive that if a low TSH is commensurate with good health that a high free T3 and free T4 would be as well. Total T3 levels can vary depending on the amount of binding proteins available which is influenced by many different factors like liver disease malnutrition and pregnancy.

In a healthy person TSH T3 and T4 are optimal and body temperature is 986. These metrics are a good point of reference to use when trying to identify your optimal values. Optimal is a feeling not a number.

Free T3 – Free T3 may be the most important measure of thyroid function in the serum because it measures the free and active thyroid hormone. Some research suggests that this range should actually be more like 045 to 25 mIUL. We like to see a Free T3 level greater than 32.
