The Thyroid Function – Diagnosis & Monitoring profile is designed to assess how well your thyroid gland is working by measuring two essential thyroid hormones: Thyroid Stimulating Hormone (TSH) and Free T4 (FT4).
The thyroid plays a vital role in regulating metabolism, energy production, body temperature, heart function, and overall wellbeing. Even mild changes in thyroid function can affect many aspects of your health, making blood testing the most reliable way to detect thyroid disorders.
This profile is suitable for both individuals investigating possible thyroid symptoms and those already diagnosed with a thyroid condition who require ongoing monitoring.
The test can be completed using either a finger-prick home sample or a phlebotomy blood sample.

Thyroid disorders are among the most common hormonal conditions, yet many people remain undiagnosed because symptoms often develop gradually and can easily be mistaken for other health issues.

The test is commonly used to investigate both:
Regular thyroid testing may be particularly beneficial for:
The thyroid gland produces hormones that regulate metabolism, growth, energy production, and numerous essential bodily functions. Measuring both TSH and Free T4 provides a clear assessment of thyroid performance.
Free T4 (Thyroxine)
Free T4 is one of the main hormones produced by the thyroid gland and plays a central role in regulating metabolism, energy levels, body temperature, and normal organ function. Measuring the free, biologically active portion of thyroxine helps determine whether your thyroid is producing the correct amount of hormone.
Abnormal Free T4 levels may be associated with symptoms such as fatigue, weight changes, hair loss, reduced concentration, fertility issues, or changes in heart rate.
Thyroid Stimulating Hormone (TSH)
TSH is produced by the pituitary gland and controls how much thyroid hormone your thyroid releases. It is one of the most important laboratory markers for identifying both underactive and overactive thyroid conditions.
High or low TSH levels can indicate thyroid dysfunction even before significant symptoms develop. When assessed alongside Free T4, it provides a reliable overview of your thyroid health and helps support both diagnosis and ongoing monitoring of thyroid disorders.
