The biggest influence on basal metabolic rate (BMR) is exerted by hormones from the thyroid gland — T3 thyroid hormone.
<h3>What are T3 levels a sign of?</h3>
- A person's thyroid is producing enough T3 hormone when their T3 levels are normal.
- Low levels may be a sign of hypothyroidism, while high levels may be an indication of hyperthyroidism.
- T3 levels, however, can also be influenced by other variables, such as pregnancy and some drugs.
<h3>What takes place when T3 levels are high?</h3>
High total T3 or high free T3 levels in your test findings could indicate hyperthyroidism.
You may have hypothyroidism, a condition in which your body doesn't produce enough thyroid hormone, if your T3 levels are low.
To assist in the diagnosis of thyroid illness, T3 test results are frequently matched with T4 and TSH test findings.
