Cancer Detection Programs
Biodesix advances two distinct molecular residual disease blood-testing programs for cancer detection.

Key Points
1
Biodesix CEO Scott Hutton said the company is developing both approaches so “the clinical question can drive the testing strategy,” rather than requiring one approach for every patient.
2
Biodesix says tumor-informed testing is generally the most sensitive option when tumor tissue is available, while tumor-naïve testing can extend monitoring to patients without usable tissue.

The programs are designed to run on partner platforms already installed in laboratories around the world; Hutton said this could help reach patients beyond those served by a centralized laboratory model.

Memorial Sloan Kettering has institutional financial interests in Biodesix, according to the report describing the validation collaboration.
Biodesix is developing two blood tests to detect cancer that lingers or returns after treatment using different detection methods. The tumor-informed approach, built with Bio-Rad, hunts for patient-specific tumor DNA in the blood using digital PCR technology. The tumor-naïve program with Thermo Fisher spots methylated tumor DNA through genetic sequencing—a method that works even when tumor tissue is unavailable MarketScreener.
Both tests are still being validated at Memorial Sloan Kettering Cancer Center and do not yet prove they improve patient outcomes. CEO Scott Hutton said the dual approach lets doctors choose the right test for each patient rather than forcing one method for everyone MarketScreener.
Tumor DNA Detection Through Two Different Routes
The tumor-informed test requires tumor tissue from a patient's cancer. It uses the patient's unique tumor changes to build a custom DNA search. Then digital PCR finds circulating tumor DNA—cancer DNA floating in the blood. This method is generally the most sensitive when tumor samples are available MarketScreener.
The tumor-naïve test doesn't need tumor tissue. It instead looks for methylated DNA—genetic material with chemical tags added by cancer cells—using next-generation sequencing. This opens testing to patients whose tumors were removed, are too small to sample, or don't have enough tissue available MarketScreener.
Partner Platforms Could Expand Patient Reach
Both programs run on lab equipment already installed worldwide through Bio-Rad and Thermo Fisher. This avoids requiring patients to send samples to a single centralized lab. CEO Hutton said the partner platforms mean more hospitals and cancer centers can offer the tests locally MarketScreener.
Using existing lab infrastructure could speed adoption. Hospitals wouldn't need to buy new machines or rebuild workflows. The tests integrate into labs that already use these partner platforms daily MarketScreener.
Validation Still Underway at Leading Cancer Center
Memorial Sloan Kettering is the primary research partner validating both tests. The center has a financial stake in Biodesix, which the company disclosed transparently MarketScreener. Researchers are still measuring how accurately each test detects residual cancer.
The validation step matters because detecting cancer DNA in blood is only the first milestone. The real goal is proving these tests help doctors catch cancer sooner and improve survival. That evidence hasn't been established yet MarketScreener.
