How to read your patient’s test results
The Oncodetect™ Molecular Residual Disease (MRD) test report is simple and straightforward, showing whether circulating tumor DNA (ctDNA) was detected in your patient’s blood, as well as a chart of their ctDNA levels over time.

Explore the report
The Oncodetect MRD report provides a simple view of a patient’s MRD status and allows for the tracking of ctDNA levels over time. Knowing a patient’s MRD status can help you to guide adjuvant therapy, detect recurrence or progression earlier than the current standard of care,1 and assess their response to treatment.

Positive or negative
The report begins with a positive or negative result (detected or not detected), indicating the presence or absence of ctDNA associated with your patient’s tumor. A positive result indicates a higher risk of cancer recurrence or progression. A negative result correlates with a better prognosis for the patient.2

Amount detected
If ctDNA is detected,* the amount of ctDNA in your patient’s bloodstream will be stated as mean tumor molecules per milliliter of plasma (MTM/mL).

Longitudinal monitoring
Track your patient’s ctDNA levels over time — pre-surgery, post-surgery, during and after adjuvant therapy, during patient surveillance, and, as needed, upon recurrence. This lets you monitor tumor burden, detect recurrence, and assess response to therapy.
Breaking down the results
Each Oncodetect MRD report will show the amount of tumor-specific ctDNA in your patient’s bloodstream. If you are monitoring MRD over time, you’ll get a historical view of your patient’s levels, showing quantifiable evidence of cancer recurrence, progression, or regression.
Negative
A “ctDNA not detected” result indicates there is no identifiable evidence of MRD, and could signify a lower risk of recurrence or progression.2†

Positive
A “ctDNA detected” result indicates a higher risk of recurrence or progression. Knowledge of a positive result and the trajectory of ctDNA levels over time can help inform the best treatment plan for a patient.
