👉The primary application of ThyroSeq is to provide accurate cancer diagnosis in thyroid nodules with indeterminate FNA cytology.
👉Indeterminate FNA cytology encompasses diagnostic categories III, IV, and V of the Bethesda System for Reporting Thyroid Cytopathology.
👉Uncertain and variable risk of cancer in these nodules hampers clinical management of these patients.
👉ThyroSeq stratifies thyroid nodules with indeterminate cytology into those that are most likely benign and can frequently be followed by observation and those that have a high probability of being cancer or pre-cancer, which in most cases need surgical management.

👉ThyroSeq Clinical Validation Study Overview
- Reported in the premiere medical journal – JAMA Oncology (Steward, DL et al. JAMA Oncol. 2018.)
- Largest prospective double-blind multicenter study of any commercially available molecular test
- Highest NPV (97%) and PPV (66%) among well validated tests
- Highest reduction in diagnostic surgery – allowing avoidance of surgery for up to 61% of all Bethesda III/IV nodules and 82% of indeterminate nodules with benign pathology
- Reliable detection of all types of thyroid tumors including Hurthle cell cancer
- Reports probability of cancer and predicted risk of cancer recurrence, empowering individualized patient management
