Thyroid gland is the master regulator of metabolism, energy, and hormonal balance.

The Thyroid Function BioMap includes the three most essential markers for assessing thyroid function, metabolism, and hormonal balance. By evaluating these together, you get a comprehensive picture of thyroid health.

BioMap included tests are listed below.

    • Reference range: 2.3–4.2 pg/mL

    • Optimal range: 2.5–3.5

    • T3 (triiodothyronine) is a thyroid hormone produced by the thyroid gland, that plays an essential role in metabolism, energy production, and cognitive function. Free T3 is not bound to proteins and can enter bodily tissue.

    • Low Free T3 is associated with slow metabolism, weight gain, fatigue, and brain fog.

    • High Free T3 can indicate hyperthyroidism, leading to symptoms like rapid heartbeat, anxiety, and weight loss.

    • Reference range: 0.8–1.8 ng/dL

    • Optimal range: 1.0–1.5

    • T4 (thyroxine) is a hormone produced by the thyroid gland.

    • T4 is considered to be a prohormone, as it has minimal biological activity on its own.

    • The body converts T4 into T3 (triiodothyronine), the active form, primarily in the liver, kidneys, and other tissues.

    • T3 binds to nuclear receptors and directly regulates metabolism, temperature, energy, and more.

    • Free T4 is crucial for understanding how much thyroid hormone is available for conversion to T3.

    • Reference range: 0.40–4.50 mIU/L

    • Optimal range: 0.5–2.0

    • TSH (Thyroid-Stimulating Hormone) is produced by the pituitary gland.

    • TSH levels in the blood control how much T3 and T4 the thyroid produces, which are hormones regulating metabolism, energy levels, and other vital bodily functions.
