PRESS RELEASE: SABCS23: REVEAL GENOMICS® unleashes groundbreaking DNADX® liquid biopsy data for metastatic breast cancer

INFORMATION FOR HEALTHCARE PROFESSIONALS

Packaging of the product DNADX

DNADX® analyzes tumor tissue or plasma circulating tumor DNA to identify clinically relevant biomarkers. The test provides Copy Number Alteration (CNA)-based molecular subtyping* and reports Single Nucleotide Variants (SNVs), indels, and CNAs in breast cancer driver genes.

DNADX®  is a groundbreaking test designed for patients facing advanced breast cancer.

Our proprietary software, used for diagnostic testing, examines the DNA from tumor tissue or circulating tumor DNA (ctDNA) in the blood.

By analyzing distinctive gene patterns, we uncover crucial details that go beyond single gene alterations, offering valuable insights to shape personalized and targeted treatment plans.
