Triiodothyronine
Explanation: Triiodothyronine (T3) is a hormone made by the thyroid gland, a small butterfly-shaped gland in the neck. It plays an important role in regulating metabolism, heart rate, body temperature, digestion, and overall energy levels. While some T3 is made directly by the thyroid, most of it comes from the conversion of another thyroid hormone, thyroxine (T4), into T3.
Test purpose: Testing T3 levels helps detect and manage thyroid conditions.
- Detect thyroid conditions such as hyperthyroidism (overactive thyroid), hypothyroidism (underactive thyroid), or other thyroid problems: Evaluate symptoms of thyroid imbalance: Symptoms like rapid heartbeat, weight changes, fatigue, sweating, or mood swings may be linked to abnormal T3 levels.
- Differentiate thyroid conditions: In some cases, T3 may be elevated even if T4 levels are normal, helping to identify specific types of thyroid disorders like T3 toxicosis.
- Monitor thyroid treatment: For people on thyroid medication or treatment, T3 levels can indicate if the therapy is working effectively.
