What is molecular or gene testing?

  • When a thyroid nodule is biopsied, the pathologist cannot always tell if the nodules is benign (meaning no cancer) or malignant (meaning cancer is present). These nodules are considered “indeterminate.”
  • Molecular or gene testing helps doctors estimate the risk that a nodule is cancer.
  • Several different types of molecular or gene tests exists. Some examples are the Afirma® and the ThyroSeq® tests.
