Can you tell me what 'normal' levels of TSH and T4 would be?

Question

I have hypothyroidism and my doctor always reads the numbers out to me and says this is high or low, but I'd like to know what the normal range is.

Answer 1

TSH 0.40 - 5.5

T4, FREE 0.8 - 1.8

Answer 2

Test / Name Normal Range Interpretation
"TSH" Test -- Thyroid Stimulating Hormone / Serum thyrotropin 0.4 to 6 0.3 to 3.0 (as of 2003) Under .4 can indicate possible hyperthyroidism. Over 6 is considered indicative of hypothyroidism. Note: the American Association of Clinical Endocrinologists has revised these guidelines as of early 2003, narrowing the range to .3 to 3.0. Many labs and practitioners are not, however, aware of these revised guidelines. (See Endos Say Normal TSH Range Now .3 to 3: Millions More at Thyroid Risk)
Total T4 / Serum thyroxine 4.5 to 12.5 Less than 4.5 can be indicative of an underfunctioning thyroid when TSH is also elevated. Over 12.5 can indicate hyperthyroidism. Low T4 with low TSH can sometimes indicate a pituitary problem.
Free T4 / Free Thyroxine - FT4 0.7 to 2.0 Less than 0.7 is considered indicative of possible hypothyroidism.
T3 / Serum triiodothyronine 80 to 220 Less than 80 can indicate hypothyroidism
