What This Test Measures
Thyroid Signalling
Checks thyroid stimulating hormone (TSH), which helps show how the brain is signalling the thyroid gland.
Thyroid Hormone Levels
Measures FT4, FT3 and total thyroxine (T4), providing insight into thyroid hormone availability and thyroid related metabolic activity.
Thyroid Autoimmunity
Includes TPOAb and TgAb, which may provide context around autoimmune thyroid patterns.

Biomarkers included – Thyroid Test Medium
- Thyroid Stimulating Hormone: Thyroid Signalling — Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland to regulate the production of hormones by the thyroid gland. It is a critical indicator of thyroid health, used to screen for conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).
- Free Triiodothyronine (fT3): Thyroid Hormone Levels — Free Triiodothyronine (fT3) is the unbound, active form of the thyroid hormone triiodothyronine (T3). It is crucial for regulating metabolism, energy levels, body temperature, and heart function. Measuring fT3 provides a direct assessment of the biologically active thyroid hormone available to tissues, reflecting current thyroid function more accurately than total T3 in many cases.
- Thyroxine (T4): Thyroid Hormone Levels — Thyroxine (T4) is the primary hormone produced and released into the bloodstream by the thyroid gland. It plays a critical role in regulating the body's metabolic rate, heart function, and digestive processes, serving as a precursor to the more active hormone, T3.
- Free Thyroxine (fT4): Thyroid Hormone Levels — Free Thyroxine (fT4) is the unbound, active form of the thyroid hormone thyroxine in the bloodstream. It's crucial for assessing thyroid function because it directly reflects the amount of hormone available to regulate metabolism, growth, and energy levels. Measuring fT4 helps diagnose and monitor conditions like hyperthyroidism (too much) or hypothyroidism (too little) thyroid hormone.
- Thyroglobulin: Thyroid Autoimmunity — Thyroglobulin is a protein produced by the thyroid gland that serves as the substrate for the synthesis of thyroid hormones T3 and T4. It is primarily used as a tumor marker to monitor for the recurrence of thyroid cancer after the thyroid gland has been surgically removed.
- TPOAb (Thyroid Peroxidase Antibodies): Thyroid Autoimmunity — TPOAb (Thyroid Peroxidase Antibodies) are autoantibodies that attack thyroid peroxidase, an enzyme critical for thyroid hormone production. Their presence indicates an autoimmune thyroid condition, such as Hashimoto's thyroiditis or Graves' disease, which can lead to hypothyroidism or hyperthyroidism, respectively. Measuring TPOAb helps diagnose and monitor these autoimmune thyroid disorders.
Frequently asked questions – Thyroid Test Medium
How is Thyroid Test Medium different from Thyroid Test Small?
Thyroid Test Medium includes the same key thyroid function markers as Thyroid Test Small, with added thyroid antibodies and total T4 for broader thyroid insight.
Why are thyroid antibodies included?
Thyroid antibodies may provide context around autoimmune thyroid patterns, which can be relevant when exploring thyroid related symptoms or ongoing thyroid concerns.
Can I reschedule my appointment?
Yes, appointments can be rearranged. Please provide sufficient notice before your scheduled appointment.
What happens if my sample cannot be analysed?
If a sample is unsuitable for analysis, our customer support team will contact you with information about the next steps.
Customer reviews – Thyroid Test Medium
4.7/5 (3)
- 5/5 — Fast service and the nurse was very professional during the home visit.
- 5/5 — Great way to check my thyroid levels without the GP hassle.
- 4/5 — The digital report was easy to read, but I wish the AI summary had a bit more detail. Results came back in one day which was great.
