What is FoundationOne Liquid?

FoundationOne Liquid helps guide cancer care from a simple blood draw.

This liquid biopsy test provides targeted gene and microsatellite instability (MSI) results1 that can help direct therapy selection and clinical trial options for advanced-stage cancer patients using a minimally invasive sample type. By analyzing ctDNA with our comprehensive genomic profiling approach and providing expertly curated reports, FoundationOne Liquid empowers providers to make more informed clinical decisions even when tissue is not ideal.

1 MSI status will be reported for samples determined to have high microsatellite instability.

2 >99% PPV for all alterations, calculated as a weighted average of the PPV for each class of alteration, with the weighting based upon the frequency with which FoundationACT detects each class of alteration. The PPV for base substitutions, indels and rearrangements is >99% at >0.5% MAF. The PPV for copy number variations at ≥20% tumor fraction is 97.6%. Internal data on file.

3 >99% sensitivity for base substitutions, indels and rearrangements at >0.5% MAF. Sensitivity for copy number variations is >95% when the tumor fraction is ≥20%. Internal data on file.
