About this profile

The Thyroid Profile I Test is a comprehensive blood test that evaluates the health and function of your thyroid gland — a small but powerful gland responsible for regulating your metabolism, energy, mood, and overall well-being.

This private thyroid blood test measures three essential hormones that control how your body uses energy:

What’s Included in the Thyroid Profile I Test?

✔ TSH (Thyroid Stimulating Hormone):
Produced by the pituitary gland, TSH controls how much T3 and T4 the thyroid should release. Elevated or low levels of TSH often signal thyroid dysfunction.

✔ Free T3 (Triiodothyronine):
The active thyroid hormone that helps regulate metabolism, body temperature, and heart rate. Low or high levels of Free T3 may indicate hypothyroidism or hyperthyroidism.

✔ Free T4 (Thyroxine):
This hormone is converted into T3 in the body and plays a critical role in energy balance and metabolic rate. It helps diagnose thyroid hormone imbalances.

Why Choose the Thyroid Profile I Test?

  • Detect early signs of underactive (hypothyroid) or overactive (hyperthyroid) function
  • Identify causes of fatigue, weight gain/loss, mood changes
  • Monitor ongoing thyroid treatment or health conditions
  • Quick, confidential, and professional testing available across the UK

If you’re experiencing symptoms such as low energy, mood swings, or weight issues, this test offers a simple and reliable way to assess your thyroid health.
