Delfi Detects What Others Cannot
We are creating next-generation liquid biopsies fueled by breakthroughs in genomics and machine learning to revolutionize early cancer detection.
Unlocking a Vast Trove of Diagnostic Data
Our unique, genome-wide fragmentomic-based approach to early detection isn’t limited to the small number of mutations or alterations detected by other liquid biopsies, which are just pieces of a much larger picture.
Higher Performance Than Other Methods
By examining cell-free DNA fragments across the genome, Delfi’s machine learning system analyzes orders of magnitude more data on the presence or absence of cancer than possible with conventional technologies that look for limited changes in DNA sequences, methylation, or proteins. Delfi’s highly accurate assays are not affected by confounding conditions such as clonal hematopoiesis of indeterminate potential (CHIP) or other diseases.
A Growing Body of Evidence
First published in Nature in 2019, Delfi’s methods continue to demonstrate the potential of using this technology to develop high-performing, accessible liquid biopsy tests.

FRAGMENTOMICS studies the physical properties of circulating cell-free DNA fragments. DNA is packaged abnormally in cancer cells, resulting in abnormal fragment patterns when cancer cells die and release their DNA into the bloodstream. Cell-free DNA fragments in the blood can indicate the presence of cancer and suggest its likely location in the body.
