About DELFI Diagnostics

DELFI Diagnostics is developing next-generation, blood-based tests that are convenient, accessible, and reliable, offering a new way to help detect cancer. DELFI's proprietary technology leverages advanced AI to analyze patterns of circulating cell-free DNA fragments in the blood, an approach known as fragmentomics, to help detect lung cancer with high sensitivity. FirstLook Lung, the first commercially available blood-based screening test for lung cancer in the United States, serves individuals eligible for lung cancer screening through a simple blood draw that integrates with routine blood work. With a negative predictive value of 99.8 percent, the test identifies individuals at elevated risk for lung cancer, including early-stage disease, and guides them toward follow-up with guideline-recommended low-dose CT. Through novel health system partnerships, DELFI is pioneering electronic medical record (EMR) integration that makes blood-based testing available to historically underserved populations. FirstLook Lung has not been cleared or approved by the FDA.

DELFI-Tumor Fraction (DELFI-TF) is a liquid biopsy research service for monitoring late-stage cancer patients during their course of treatment. As a versatile precision medicine platform, DELFI-TF provides a non-invasive, tissue-free, and tumor-agnostic quantitative estimate of tumor burden at the time of the blood draw. Based on the standard DELFI cfDNA assay, DELFI-TF overcomes many of the barriers of currently available monitoring products, such as cost, turnaround time, sensitivity, and tissue biopsy, while maintaining market-level performance. DELFI-TF provides critical therapeutic monitoring insights across all solid cancer and treatment types by establishing molecular profiles, tracking therapeutic effectiveness, and identifying emerging resistance patterns earlier than traditional methods. DELFI-TF has not been cleared or approved by the FDA and is intended for research use only.
