These levels are influenced by many factors that affect protein levels in the body, including medications, sex hormones, and liver disease. A normal Total T4 level in adults ranges from 5.0 to 12.0μg/dL. A normal Total T3 level in adults ranges from 80-220 ng/dL.

What is the difference between free T3 and T4 and total T3 and T4?

Free T4 travels into body tissues that use T4. Bound T4 attaches to proteins that prevent it from entering these tissues. More than 99\% of T4 is bound. Because T4 is converted into another thyroid hormone called T3 (triiodothyronine), free T4 is the more important hormone to measure.

What does a low TSH level mean on a T3 test?

A normal free T3 level with a low TSH level might indicate subclinical hypothyroidism. A normal free T3 level with an elevated TSH level might indicate subclinical hyperthyroidism. An elevated free T3 test indicates hyperthyroidism and is virtually always accompanied by elevated free T4 and low TSH levels.

What is the normal range for TSH?

TSH stands for Thyroid Stimulating Hormone– a standard blood test will produce a number of how well your thyroid is performing. Normal range for an adult is typically considered to be between .4 and 4.0 (1); however, in my practice I would say ideal is between 0.5 and 1.5.
