Within the past few years, several molecular tests have become available to help determine whether some nodules are cancerous or benign. These tests look at many genes within the thyroid nodule’s genetic make-up (DNA). They are being used when a nodule biopsy comes back with a diagnosis of ‘indeterminate’. Sometimes, the person doing the biopsy will perform an additional pass of the needle to obtain material for such a test. This may be done on the first biopsy or at the time of a repeat biopsy.

Ask if your FNA physician can collect and hold a sample for marker testing just in cast the result is indeterminate. It can be discarded if the result is benign.
