The thyroid is a butterfly-shaped gland placed in the front part of the neck, and it produces the thyroid hormones. These hormones traverse the bloodstream, regulating several aspects of the body’s metabolism affecting temperature, weight, and energy. When physicians observe abnormalities in these or related parameters, they advise testing the thyroid gland’s functioning by measuring the quantum of thyroid hormones in the blood.
Thyroid function tests done at Maurya Labs Purnia in Bihar require blood samples. The thyroid function tests reveal whether the thyroid is normal, overactive (hyperthyroidism) or underactive (hypothyroidism).

Thyroid blood tests are diagnostic tools for ascertaining thyroid disorders associated with hyper- or hypothyroidism. Such conditions include thyroiditis, Graves’ disease, Hashimoto’s disease, thyroid tumours, goitre, thyroid nodules or lumps, and thyroid cancer. Thyroid Stimulating Hormone (TSH) level, which regulates the balance of thyroid hormones (including T3, T4) in the body, is a primary indicator.
The thyroid test results done at Mauruya Labs, Purnia in Bihar show levels of TSH, T3, T4. High TSH and low T3, T4 indicate an underactive thyroid, while the converse implies an overactive thyroid. Thyroid antibodies and calcitonin values inform the doctor of thyroiditis, type 1 diabetes, or rheumatoid arthritis which are also done at Maurya Labs Purnia, Bihar in case of derranged thyroid function test results.

What does the TFT Measure?
A Thyroid Function Test measures the amount of T3 (Triidothyronine), T4 (Thyroxine) and TSH (Thyroid Stimulating Hormone). T3 and T4 are the two main hormones that are produced by the thyroid. T3 and T4 are collectively known as thyroid hormone, which controls the body's metabolism, growth, and other bodily functions. They affect the heart, weight, body temperature, muscle strength, and mood. In children, thyroid hormones also affect growth.
TSH is measured first, with the normal adult range being 0.40 - 4.50 mIU/mL
T3 is measured [normal 100 - 200 ng/dL
T4 [normal 5.0 – 11.0 ug/dL
Why should I do the Thyroid Function Test ?
The main reason for the thyroid test is when doctor suspect that you are having hyper thyroidism or hypo thyroidism.
