Improved patient access

Our commitment is to improve patient access to personalized and tumor-informed testing to help guide treatment decisions

When Is Signatera Used?

Signatera is a tool that allows physicians to stratify their patients, closely monitor the effectiveness of adjuvant therapy and detect early relapse better than conventional tools. Signatera is a custom-built and tumor informed molecular residual disease (MRD) assay used to inform the presence of circulating tumor DNA (ctDNA), enabling physicians to get in front of disease or provide patients with much-needed peace of mind.

  • Risk Stratification
    After surgical resection to inform adjuvant treatment decisions
  • Recurrence monitoring
    To find early signs of cancer recurrence in patients with a previous cancer diagnosis
  • Therapeutic response
    To monitor the cancer’s response to treatment like immunotherapy (IO) on a molecular level

Natera accepts all commercial and public insurances
