Oncodetect™ Molecular Residual Disease test

Make circulating tumor DNA stand out among cell-free DNA

The Oncodetect Molecular Residual Disease (MRD) test quantifies and monitors levels of circulating tumor DNA (ctDNA) in the blood. The results can help you make more personalized treatment decisions regarding adjuvant therapy, cancer recurrence, and response to treatment.

Turn insights into action

The tumor-informed Oncodetect Molecular Residual Disease (MRD) test provides clear, quantitative† MRD results on which to base your patient’s treatment decisions. The test report can help guide adjuvant therapy decisions, monitor cancer recurrence, and assess response to treatment.6

Guide adjuvant therapy

Gain insight into your patient’s risk for cancer recurrence or progression.6 Oncodetect MRD test results can help inform the use and intensity of therapy.

Early detection of recurrence

MRD testing can identify recurrence sooner than standard-of-care imaging,1,6 enabling you to intervene earlier, adjust follow-up frequency, and possibly improve patient outcomes.

Therapy response

Assess your patient’s response to therapy through ongoing monitoring, which can help inform the intensity and duration of treatments.

MRD testing can change the course of cancer care throughout the treatment journey2-5

Highly personalized, highly sensitive6

The Oncodetect MRD test tracks up to 200 variants specific to a patient’s tumor, granting more opportunities to detect ctDNA in the blood.6,7 It also has a low limit of detection — 0.005% variant allele frequency (VAF) — so it can detect MRD with high sensitivity6 after surgery or at the early stages of recurrence. To minimize false negatives in most clinical scenarios, the limit of detection should be below 0.01%.8
78%

In the post-surgical setting, the Oncodetect MRD test correctly identified 78% of colorectal cancer patients whose cancer would recur.6

94%

In the surveillance setting, the Oncodetect MRD test correctly identified 94% of patients with stage III colorectal cancer whose cancer would not recur.6

91%

In the surveillance setting, the Oncodetect MRD test correctly identified 91% of patients with stage III colorectal cancer whose cancer would recur.6

Up to 200 variants

The tumor-informed Oncodetect MRD test analyzes up to 200 variants specific to your patient's cancer to detect even a slight amount of ctDNA.6

The Oncodetect MRD test can detect cancer recurrence more than 2 years earlier than imaging.6

The Oncodetect MRD test provides residual disease detection and monitoring, allowing you and your patient to make more informed treatment decisions.

MRD testing could benefit over 3 million patients—including yours

It’s estimated that 3+ million patients in the United States alone could benefit from MRD testing,‡ and your patient could be one of them. The Oncodetect MRD test can detect and monitor ctDNA levels in the blood of patients with solid tumors,§ allowing you to make treatment decisions with more confidence.

    This test was developed, and its performance characteristics determined by Genomic Health, Inc. The Oncodetect test was clinically validated in colorectal cancer patients with stage II-IV disease. Performance characteristics may not apply in tumor types not included in this test’s clinical validation. The test has not been cleared or approved by the US Food and Drug Administration. The test has been validated as a Laboratory Developed Test per institutional and applicable CLIA regulation (CLIA# 03D2048606) and College of American Pathology (CAP# 8869063) as qualified to perform high complexity clinical laboratory testing.
