The Thyroid Profile Total Test is a blood test that measures the levels of Total T3 (Triiodothyronine), Total T4 (Thyroxine), and Ultra-Sensitive TSH (Thyroid Stimulating Hormone) to evaluate thyroid gland function.
This test helps detect and monitor thyroid disorders such as hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), and thyroid hormone imbalance. It is commonly recommended for individuals experiencing symptoms like fatigue, weight changes, irregular heartbeat, hair loss, mood changes, or metabolism-related concerns.
1.T4 (Total Thyroxine)
The main hormone made by the thyroid gland; measures total T4 (protein-bound and free) to assess thyroid function and metabolism.
2.T3 (Total Triiodothyronine)
An active thyroid hormone with a strong effect on metabolism, heart rate, digestion and body temperature; measures total T3 in the blood.
3.TSH Ultra-Sensitive (Thyroid Stimulating Hormone)
Made by the pituitary gland to control thyroid hormone production; the ultra-sensitive test detects small changes in thyroid function.
Also known as: Total Thyroid Function Test, Thyroid Function Test (TFT), T3 T4 TSH Test, Thyroid Panel Test, Thyroid Hormone Profile Test
The Thyroid Profile Total Test evaluates the hormones produced and regulated by the thyroid gland. The thyroid gland, located in the neck, produces hormones that control important body functions including metabolism, energy production, body temperature regulation, heart function, and growth.
The test measures total levels of thyroid hormones circulating in the blood, including hormones bound to proteins and the biologically available portion. TSH helps regulate thyroid hormone production and provides important information about communication between the pituitary gland and thyroid gland.
The test measures three important thyroid-related hormones.
T4 (Total Thyroxine):
Total T4 is the primary hormone produced by the thyroid gland. It plays an important role in:
High Total T4 levels may be seen in:
A Thyroid Profile Total Test may be recommended for:
The test requires a blood sample collected from a vein.
Before the test:
| Parameter | Normal range |
|---|---|
| TSH Ultra-Sensitive | Approximately 0.4–4.0 mIU/L |
| Total T4 (Thyroxine) | Approximately 5–12 µg/dL |
| Total T3 (Triiodothyronine) | Approximately 80–200 ng/dL |
| Note | Reference ranges may vary depending on age, pregnancy status, laboratory methods, and individual health conditions. Thyroid test results should always be interpreted by a qualified healthcare professional along with symptoms and medical history. |
Reference ranges can differ between labs. Your report shows the range used by the lab.
A Thyroid Profile Total Test is a blood test that measures Total T3, Total T4, and TSH levels to evaluate thyroid gland function.
Total T3 and T4 measure both protein-bound and available hormone levels, while Free T3 and Free T4 measure only the unbound active hormone portion.
No. Fasting is generally not required unless advised by your healthcare provider.
High TSH levels commonly indicate that the thyroid gland is not producing enough thyroid hormone, which may suggest hypothyroidism.

Low Total T4 levels may indicate:
T3 (Total Triiodothyronine):
Total T3 is an active thyroid hormone that has a strong effect on metabolism and energy regulation. It helps regulate:
High T3 levels may occur in:
Low T3 levels may occur in:
TSH Ultra-Sensitive (Thyroid Stimulating Hormone):
TSH is produced by the pituitary gland and controls thyroid hormone production. It acts as a communication signal between the brain and thyroid gland.
High TSH levels may suggest:
Low TSH levels may suggest:
Ultra-sensitive TSH testing can detect small changes in thyroid function.
Doctors may recommend a Thyroid Profile Total Test to:
The test may be advised if you experience:
Benefits of the Thyroid Profile Total Test:
Low TSH levels may indicate increased thyroid hormone production or hyperthyroidism.
Yes. Thyroid hormones regulate metabolism, and abnormal levels may contribute to unexplained weight gain or weight loss.
Yes. Thyroid hormone imbalance may contribute to hair loss, dry skin, or changes in skin texture.
Testing frequency depends on symptoms, thyroid condition, medications, and your healthcare provider's recommendation.
Yes. Pregnancy can change thyroid hormone levels, and pregnancy-specific reference ranges may be used for interpretation.
