ABOUT TOTAL T3 TESTS
The Total T3 test evaluates the overall level of triiodothyronine hormone, which plays a vital role in regulating metabolism, heart rate, and body temperature. This test measures both the free (active) and bound (inactive) T3 circulating in the bloodstream. It is often used to help diagnose hyperthyroidism and monitor thyroid disorders in conjunction with other thyroid hormone tests.
Consider this test if you have symptoms like unexplained weight changes, anxiety, tremors, or palpitations, or if your healthcare provider wants to assess your thyroid status more fully.
The test measures the total T3 hormone level in your blood, including both free and protein-bound T3.
It helps detect thyroid imbalances such as hyperthyroidism and complements other thyroid tests for a comprehensive diagnosis.
No special preparation is necessary. You can have the blood drawn at any time unless otherwise instructed.
