    Test Details

    The multi-target stool (mt-sDNA) test in a non-invasive, at-home colorectal cancer (CRC) screening tool that identifies molecular markers associated with cancer cells in stool samples.1 It is an effective screening tool for patients of any gender, age 45+, and at average risk of developing CRC.1,2  Learn more about how a positive mt-sDNA result may indicate the presence of CRC or Advance Adenoma (AA) and the process for sample collection.

    Key Performance Studies

    Two studies evaluated the performance and specificity of screening with mt-sDNA as a tool to detect CRC in patients at average risk: DeeP-C2  (asymptomatic, average-risk adults, ages 50-84) and Act Now3 (average-risk adults, ages 45-49). Learn more about the data supporting mt-sDNA screening.

    Additional Evidence

    Real-world data demonstrates that mt-sDNA is an effective modality for CRC screening in diverse clinical practice.4 It has high adherence rates5,6 and has been shown to be cost effective.7 Learn more about mt-sDNA testing performance in real-world settings.

    Modeling

    Cancer models are an important tool to help understand the value of healthcare interventions where research is not ethical or feasible.8 Learn more about the models used in CRC screening decision-making.9
