Detailed explanation-2: -T4 Production All T4 in your body is produced by the thyroid gland-about 80 to 100 micrograms (mcg) per day. Roughly 10 times that amount of T4, about 1000 mcg, is constantly circulating in your blood.
Detailed explanation-3: -TSH, in turn, stimulates thyroid follicular cells to release thyroxine or T4 (80%), and triiodothyronine or T3 (20%).
Detailed explanation-4: -A normal Total T4 level in adults ranges from 5.0 to 12.0g/dL. A normal Total T3 level in adults ranges from 80-220 ng/dL.
Detailed explanation-5: -A typical normal range is: 4.5 to 11.2 mcg/dL (micrograms per deciliter).
