Preparation guide

Preparation for thyroid ultrasound

Public guide to confirm clothing, necklaces, medications, previous exams, and the difference between thyroid ultrasound and puncture.

How to use this guide

There is usually no fasting. The most important steps are arriving comfortably and bringing prior reports or relevant laboratory tests.

If there is a known nodule, prior surgery, previous biopsy, or recent hoarseness, it is worth informing the team at the time of the exam.

This material summarizes the most common preparation, but the final instruction must always be confirmed with the clinic or the requesting physician.

What is commonly requested for this exam

• No fasting or special preparation needed
• Avoid necklaces and high collars
• Bring previous reports and thyroid blood tests
