Checks how well your thyroid is working by measuring the T3, T4 and TSH hormones.
Also known as: Thyroid Function Test, TFT, Thyroid Profile, T3 T4 TSH Test
The Thyroid Profile Total (T3, T4 & TSH Ultra-sensitive) is a blood test used to evaluate how well your thyroid gland is functioning. The thyroid is a small butterfly-shaped gland located in the front of the neck that produces hormones responsible for controlling metabolism, body temperature, heart rate, energy levels, and growth.
This profile measures three important thyroid hormones:
Abnormal thyroid hormone levels may indicate conditions such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). Early diagnosis helps prevent complications and allows timely treatment.
A thyroid profile test evaluates the functioning of the thyroid gland by measuring the levels of T3, T4, and TSH hormones in the bloodstream.
Doctors commonly recommend this test for:
Common thyroid disorders
Occurs when the thyroid gland does not produce enough hormones.
Common symptoms:
Occurs when the thyroid gland produces excessive thyroid hormones.
Common symptoms:
An enlargement of the thyroid gland that may occur due to iodine deficiency or thyroid disease.
Symptoms:
Small lumps inside the thyroid gland that may require further evaluation.
Although uncommon, thyroid cancer can often be successfully treated when detected early.
Benefits of thyroid profile testing:
Doctors may recommend this test if you:
1.T3 (Total Triiodothyronine)
Measures the level of the active thyroid hormone responsible for regulating metabolism, heart function and energy production.
2.T4 (Total Thyroxine)
Measures the amount of thyroxine produced by the thyroid gland. T4 is converted into T3 inside the body.
3.TSH Ultra-sensitive
Measures Thyroid Stimulating Hormone released by the pituitary gland. It is the most sensitive indicator of thyroid function.
No special preparation is usually required.
Before the test:
| Parameter | Normal range |
|---|---|
| T3 | 0.97 – 1.80 ng/mL |
| T4 | 5.53 – 14.00 µg/dL |
| TSH | 0.46 – 4.68 µIU/mL |
Reference ranges can differ between labs. Your report shows the range used by the lab.
