Hopefully its acceptable to post questions regarding thyroid in this forum. If not I apologize in advance.
I had a host of blood tests run recently which did include tsh as well as free t3 and t4. The reference range listed for the TSH on the Labcorp sheet is .35 - 5.5. My result was 3.987. I have read in several places that the AACE changed this range in early 2003 (http://thyroid.about.com/cs/testsforthyroid/a/newrange.htm) to .3 - 3.00 and suggest that people who test above 3 be treated as hypothyroidal.
Secondary to the question above I would add that my Free T3 level was 3.9 with a range of 2.3 - 4.2 and Free T4 1.02 with a range of .61 - 1.76. Although I am struggling to understand all of the variables with the thyroid processes as I understand it in laymans terms a high TSH value is the pituitary calling out for T3. Generally from what I read this is accompanied by a low T3 level and would be diagnosed as primary hypothyroidism. In my case the T3 level is actually on the high normal. Although I cant seem to find much info this appears to possibly indicate an issue with the pituitary and a possible secondary hypothyroidism.
Any thoughts would be appreciated and if this is wildy off base or crazy I apologize. Just trying to read , learn and evaluate.
