What is a high T3 reading?
If your results show high total T3 levels or high free T3 levels, it may mean you have hyperthyroidism. Low T3 levels may mean you have hypothyroidism, a condition in which your body doesn’t make enough thyroid hormone. T3 test results are often compared with T4 and TSH test results to help diagnose thyroid disease.
What does it mean when your T3 level is normal?
Normal T3 levels indicate that someone’s thyroid is producing an adequate amount of T3 hormone. High levels can indicate hyperthyroidism, and low levels can be a sign of hypothyroidism.
What are the symptoms of low free T3?
Any serious illness can decrease free T3 levels. Abnormally low T3 may cause symptoms of hypothyroidism including weakness and fatigue, cold intolerance, shortness of breath, weight gain, constipation, cognitive problems, dry skin, hoarseness, and swelling (edema). Some specific causes of low free T3 are:
Where does T3 come from in the body?
Abnormal levels of T3, which is produced in the thyroid, may signal hyperthyroidism. The thyroid is a small gland in the neck that produces hormones that regulate how the body stores and uses energy. The main hormone that the thyroid makes is thyroxine (T4). Cells in the body then convert T4 into T3.
Why do doctors order the T3 blood test?
But, doctors usually don’t order this test because the results aren’t as helpful. Doctors often order the T3 test along with other blood tests that look at thyroid function, such as the TSH test. They do this because the T3 test alone may not help them diagnose or assess your health status.

What does the T3 test tell you about your thyroid?
The T3 test simply measures how much of this hormone is present in your blood. If the level is either abnormally high or abnormally low, it can be an indicator of thyroid disease.
