The TFT – Thyroid Function Test measures key thyroid hormones in the blood to determine whether the thyroid is functioning normally, overactive (hyperthyroidism), or underact
The TFT – Thyroid Function Test is a crucial blood investigation that helps evaluate the health and performance of the thyroid gland. The thyroid is a small, butterfly-shaped gland located in the neck, but it plays a vital role in regulating metabolism, energy levels, heart rate, body temperature, and hormonal balance. Any imbalance in thyroid hormone levels can significantly impact overall health.
The TFT – Thyroid Function Test is essential for diagnosing and monitoring thyroid-related conditions. Thyroid disorders often present with vague symptoms such as fatigue, weight gain or loss, hair fall, mood changes, irregular menstrual cycles, and heart palpitations. Without proper testing, these symptoms can be easily overlooked or misdiagnosed.
This test helps doctors:
Identify hypothyroidism (low thyroid hormone levels)
Detect hyperthyroidism (excess thyroid hormone production)
Monitor ongoing thyroid treatment
Evaluate unexplained weight changes, infertility, or depression
Screen individuals with a family history of thyroid disease

2. T3 (Triiodothyronine)
Regulates metabolism and energy levels
Elevated in hyperthyroidism
3. T4 (Thyroxine)
Main hormone produced by the thyroid
Helps regulate growth, metabolism, and brain development
Some advanced panels may include Free T3 and Free T4 for more precise evaluation. At Diagnopein Diagnostic Centre Nashik, all parameters are tested using standardized quality protocols.

Testing frequency depends on individual risk factors and existing thyroid issues. It's best to discuss this with your healthcare provider for personalized guidance.
Abnormal results may suggest thyroid disorders. High TSH levels with low T4 indicate hypothyroidism, while low TSH with high T4 and T3 levels may indicate hyperthyroidism.
Typically, TFT results are available within 1 to 3 business days, allowing for timely diagnosis and treatment planning.
