Thyroid Function Tests at Tarlac Medical Center
Thyroid function tests are essential laboratory assessments that evaluate how well your thyroid gland is working. The thyroid produces hormones that regulate metabolism, energy levels, growth, and overall body function. Monitoring these hormones helps detect disorders such as hypothyroidism, hyperthyroidism, and other thyroid-related conditions.
At Tarlac Medical Center, we provide comprehensive thyroid testing, including TSH, T3, T4, Free T4, and Free T3, offering accurate results to guide diagnosis and treatment.
What Are Thyroid Function Tests?
- TSH (Thyroid Stimulating Hormone) – Regulates thyroid hormone production
- T3 (Triiodothyronine) – Active thyroid hormone affecting metabolism and energy
- T4 (Thyroxine) – Main thyroid hormone converted into active T3
- Free T4 and Free T3 – Measures active forms available to tissues
Thyroid function tests measure hormone levels in the blood to determine whether the thyroid is functioning properly. Abnormal levels may indicate thyroid dysfunction, autoimmune disorders, or other health conditions.
Why Thyroid Function Testing Is Important
- Diagnose hypothyroidism or hyperthyroidism
- Monitor thyroid hormone replacement therapy
- Detect autoimmune thyroid diseases such as Hashimoto’s or Graves’ disease
- Evaluate symptoms like fatigue, weight changes, palpitations, or mood swings
- Screen high-risk individuals including pregnant women and those with family history
Early detection ensures timely intervention and prevents complications affecting multiple body systems.
Signs You May Need Thyroid Function Tests
- Unexplained weight gain or loss
- Persistent fatigue or low energy
- Sensitivity to cold or heat
- Hair thinning or brittle nails
- Palpitations or irregular heartbeat
- Mood changes, anxiety, or depression
Routine thyroid testing may also be recommended for annual checkups or when monitoring known thyroid conditions.
Test Procedure
- Blood is drawn from a vein, usually in the morning
- Samples are sent to the laboratory for analysis
- Results are interpreted by a physician
Most thyroid tests do not require fasting, but specific instructions may be given depending on your condition or medications.
Understanding Test Results
- High TSH + Low T4/T3 – Suggests hypothyroidism (underactive thyroid)
- Low TSH + High T4/T3 – Indicates hyperthyroidism (overactive thyroid)

Results are used alongside clinical evaluation to guide treatment decisions such as hormone replacement or antithyroid medications.
