About this test

A simple way to check your thyroid function

Your thyroid gland produces hormones that help regulate metabolism, energy use, body temperature and many other processes throughout the body.

When thyroid hormone production is too low or too high, it can contribute to symptoms such as tiredness, changes in weight, sensitivity to cold or heat, changes in mood and alterations in heart rate.

This screen measures Thyroid Stimulating Hormone (TSH) and Free T4, providing a focused assessment of thyroid function. Results should be interpreted alongside symptoms, medical history and the laboratory reference ranges.
