T4 and T3 are the two energy-regulating hormones produced by the thyroid gland. These hormones also play a crucial role in maintaining body weight, temperature, and strength of your muscles. T3 is called Triiodothyronine, and like other hormones, it is found in the blood. The T3 Triiodothyronine test measures the levels of T3 in the blood, usually in 2 forms: attached or bound T3 and unattached or free T3.

This test will help detect the T3 level in your blood since an abnormal level (either too much or too little) could be an indication of several disorders. T3 (Triiodothyronine) test helps to identify hyperthyroidism effectively.
High levels of total T3 may indicate hyperthyroidism. On the other hand, low levels hint that you have hypothyroidism. To better understand the overall hormonal balance, it is better to take the T3 test, along with T4 and TSH tests.
Many symptoms may prompt your doctor to request a T3 test. Some of the symptoms may include unexplained weight loss, anxiety, shaky hands, an increased heart rate, tiredness and fatigue, sleep issues, digestive issues, and more. Since this hormone is associated with many other bodily functions, it can affect the body in many ways.
This process is relatively simple and will not take longer than a few minutes. The medical staff will clean a section on your skin, after which they will take a small sample of your blood using a needle and syringe. Your blood will then be collected in a syringe for testing.
Normal attached T3 levels are typically around 75–195 ng/dl, while free T3 is around T3 0.2–0.5 ng/dl. If your levels are higher or lower, it does not always mean you have a T3 deficiency. Your doctor will confirm the diagnosis by comparing it with your T4 and TSH tests.
T3 levels over 200 nanograms per deciliter of blood are typically considered high. Anything much more than that is an abnormally high level of T3. Even if your levels of T3 are high, do not worry. Thyroid hormone issues are an established field of study, and your doctor will help you with your treatment.
Your T3 (Triiodothyronine) test will show your T3 hormone levels in your blood. It will also show how much attached versus unattached T3 hormone is present in your blood. High levels of T3 may indicate hyperthyroidism, and low levels may be a symptom of hypothyroidism.
Low levels of T3 (and the corresponding T4) levels may indicate that your thyroid is underactive. Your thyroid may be underperforming due to some autoimmune diseases, or it may be due to thyroid surgery or even radiation therapy that was performed near the thyroid. Low levels of T3 may also occur due to starvation.
Triiodothyronine deficiency is the result of defective thyroid functioning. The thyroid gland itself can become underactive due to autoimmune diseases, medications that affect thyroid function, beta-blockers that affect the performance of thyroid hormones, thyroid surgery, or radiation therapy.
Sudden and unexplained weight loss or weight gain is one of the first external signs that you may have a T3 (Triiodothyronine) deficiency (although this can also occur for many other reasons). Other symptoms include fatigue, puffy eyes, dry skin, shaky hands, problems falling asleep, and weakness.
