Click for Blood Testing Information



T3 or triiodothyronine is the active form of the thyroid hormone. T3 acts as a metabolic throttle for fueling all of the daily cellular functions. This test measures the amount of T3 available to the tissues, or free T3.

Hypothyroidism is a condition where T3 blood levels are low. This condition causes cellular dysfunction and metabolic break-down. Symptoms may include weight gain, constipation, dry skin and hair loss. Low T3 levels may even lead to the development of chronic diseases such as heart disease and diabetes.

Hyperthyroidism is the term for elevated T3 blood levels. Symptoms can include anxiety, insomnia, heart palpitations, and bowl discomfort.

This test measures the amount of T3 available to the tissues, or free T3. Many doctors believe that evaluating the levels of free T3 is the best indicator of thyroid function. For a more extensive evaluation of thyroid function, Life Extension offers several comprehensive thyroid panels.

Fasting is not required. Take all medications as prescribed.
