The Thyroid Function Test (T3, T4, TSH) is one of the most important hormone panels for assessing thyroid gland health. It evaluates how effectively your thyroid is producing and regulating hormones that control your body’s metabolism, energy, and mood.
At Islamabad Diagnostic Centre (IDC), this test is performed with advanced automated analyzers to ensure accurate and reliable results. IDC is a leading diagnostic facility in Pakistan, known for its precision testing, professional staff, and nationwide branches.
Whether you’re struggling with fatigue, unexplained weight changes, mood swings, or irregular heartbeat, the IDC Thyroid Function Test (T3, T4, TSH) can help identify thyroid imbalances such as hypothyroidism or hyperthyroidism.
What is a Thyroid Function Test (T3, T4, TSH)?
The Thyroid Function Test (TFT) is a blood test that measures the levels of three vital hormones:
- T3 (Triiodothyronine): Regulates metabolism, temperature, and energy.
- T4 (Thyroxine): Supports metabolic rate and body functions.
- TSH (Thyroid-Stimulating Hormone): Produced by the pituitary gland to control thyroid hormone release.
Doctors recommend the T3, T4, and TSH test when you experience symptoms of thyroid imbalance or for ongoing thyroid management.
It helps diagnose:
- Hypothyroidism (underactive thyroid)
- Hyperthyroidism (overactive thyroid)
- Thyroiditis or autoimmune thyroid disorders
- Hormonal irregularities related to fertility and metabolism
Why is the Thyroid Function Test Important?
The thyroid gland influences nearly every cell in your body. When it doesn’t function properly, it can lead to widespread health problems from weight gain and fatigue to heart disease and infertility.
The Thyroid Function Test at IDC is important because it:
- Detects early thyroid problems even before major symptoms appear.
- Helps doctors evaluate medication effectiveness in thyroid patients.
- Prevents complications related to metabolism, mental health, and cardiac issues.
- Supports better management of lifestyle and hormonal disorders.
Regular monitoring ensures that your thyroid hormone levels remain stable and within a healthy range.
