New thyroid test aims to cut unnecessary surgeries
NCT ID NCT07584447
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a genetic test called Thyroid GuidePx® can help doctors and patients with papillary thyroid cancer make better treatment choices. About 85 adults with early-stage thyroid cancer will take the test before surgery. Researchers will see if the test results change the planned treatment, such as reducing the need for total thyroid removal.
