Understanding the result
This result should be interpreted with symptoms, medical history and other investigations. An abnormal value does not identify the cause by itself.
About T3-T4-USTSH
This comprehensive Thyroid Function Panel measures Total/Free T3 (Triiodothyronine), T4 (Thyroxine), and Ultra-sensitive TSH (Thyroid-Stimulating Hormone) levels in the blood. Why it is important: The thyroid gland regulates metabolism, energy production, and overall hormonal balance. This panel is crucial for diagnosing thyroid imbalances—such as hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid)—and is an essential tool for monitoring ongoing thyroid therapies.
Also known as: Thyroid Profile, Thyroid Function Test (TFT), T3 T4 Ultra-sensitive TSH, Thyroid Panel with Ultra-sensitive TSH, T3 T4 TSH Test
Who may need it?
A healthcare professional may recommend this test based on your symptoms, medical history, risk factors or need for routine monitoring.
What is the T3-T4-USTSH Test?
The T3-T4-USTSH test is a comprehensive thyroid function panel designed to evaluate how efficiently your thyroid gland is working. This panel measures the concentration of three vital hormones in your blood: Triiodothyronine (T3), Thyroxine (T4), and Ultra-sensitive Thyroid-Stimulating Hormone (USTSH). Together, these biomarkers help healthcare professionals analyze metabolic rate, hormone production, and overall endocrine balance.
What Does This Panel Measure?
This profile provides a complete assessment of thyroid health by checking three essential markers:
- T3 (Triiodothyronine): The active form of thyroid hormone that regulates cellular metabolism, energy levels, and heart rate.
- T4 (Thyroxine): The primary reservoir hormone secreted by the thyroid gland, which converts into T3 when needed by bodily tissues.
- Ultra-sensitive TSH (USTSH): A highly precise baseline marker released by the pituitary gland to regulate thyroid production. This ultra-sensitive test can detect even the most minute hormonal imbalances.
Why is the T3-T4-USTSH Test Important?
The thyroid regulates major functions like digestion, body temperature, and weight management. This test is essential for:
- Screening for and diagnosing clinical thyroid disorders such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).
- Investigating symptoms like unexplained fatigue, sudden weight shifts, hair loss, mood changes, or temperature sensitivity.
- Monitoring response rates to ongoing thyroid hormone therapies or medications.
