Both leading molecular thyroid tests may reduce the need for diagnostic surgery

A new study compared the performance characteristics of an RNA test and a DNA-RNA test for predicting the malignancy risks of the approximately 20% of thyroid nodules that display indeterminate fine-needle aspiration (FNA) cytology results. The researchers found that each test allowed nearly half of patients with indeterminate nodules to opt for observation to avoid diagnostic surgery and the possibility of lifelong thyroid hormone...
