Total T3 and Reverse T3 in Thyroid Diagnosis?
Question by charrismo: Total T3 and Reverse T3 in thyroid diagnosis?
hi,
i recently got some blood work done for my T3 and reverse T3.
however since a lot of endocrinologists do not know/ or have not read the recent studies about reverse T3 for thyroid diagnosis, they do not know how to interpret the results.
below are some extracts from the research papers….
“few practicing physicians, including endocrinologist, are aware this because it was not taught in medical school, but it contributes to low tissue levels of thyroid in a significant percentage of patients with symptoms”
AND
“Most endocrinologists believe that reverse T3 (rT3) is just and inactive metabolite with no physiologic effect, which is not the case, This study and subsequent others demonstrate that rT3 is a more potent inhibitor of T4 to T3 conversion than PTU (propylthiouracil),. In fact, rT3 is 100 times more potent than PTU at reducing T4 to T3 conversion.
anyways till i find a doctor- can someone help me calculate it so i can check if its in the normal range
thx

200-300 pmol/L is the normal range. Levels greater than 400 suggest rT3 dominance.
