What is an indeterminate thyroid nodule?

When you undergo a fine needle aspiration for a thyroid nodule, there are 3 outcome options:

  • BENIGN, 65% of cases.
  • MALIGNANT, 15% of cases (you have cancer).
  • INDETERMINATE, 20% of cases.

If your result is INDETERMINATE your risk of cancer is between 20% or 30%. Due to this risk, many patients undergo diagnostic surgery to determine the real nature of the nodule. This approach results in 70% rate of patients undergoing unnecessary surgery.

How to avoid unnecessary surgery with ThyroidPrint?

If you have an indeterminate thyroid nodule you may benefit from undergoing the ThyroidPrint test.

A benign result is predicted with a certainty greater than 95% certainty and allows to safely recommend follow up as an alternative to surgery.

If the result is malignant, the probability of cancer increases from 25% to 70%, therfore surgery is recommended.

How does ThyroidPrint work?

The test is performed by performing a new FNA of the indeterminate nodule, followed by genetic analysis to determine if the nodules is benign or malignant.
  • ThyroidPrint has a diagnostic certainty of 95%.
  • ThyroidPrint is able to avoid unnecessary surgery in 88% of cases.
