Details about Thyroid Ultrasound
What is a Thyroid Ultrasound Scan?
A thyroid ultrasound scan is a diagnostic imaging test used to examine the thyroid gland, a small butterfly-shaped gland located at the front of the neck. The thyroid plays an essential role in regulating metabolism, energy levels and hormone production.
Ultrasound imaging uses high-frequency sound waves to produce detailed images of the thyroid gland and surrounding tissues. This allows clinicians to assess the gland’s size, structure and the presence of nodules or cysts.
Because it does not use radiation, thyroid ultrasound is considered a safe, painless and effective method for evaluating structural thyroid abnormalities.
Why do I need a Thyroid Ultrasound?
A thyroid ultrasound may be recommended when there are symptoms or clinical findings suggesting thyroid abnormalities. It is often used alongside thyroid blood tests to provide a more complete assessment of thyroid health.
You may benefit from this scan if you experience:
- A lump or swelling in the neck
- Enlarged thyroid gland (goitre)
- Abnormal thyroid blood test results
- Difficulty swallowing or throat discomfort
- Persistent hoarseness
- Neck pain or tenderness
- Suspected thyroid nodules
- Monitoring of known thyroid conditions
- Family history of thyroid disease
- Follow-up after abnormal physical examination
Thyroid ultrasound helps determine whether structural abnormalities are present and whether further investigation is needed.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
