Understand a molecular diagnostic test before you act on it.

MDI explains what a test is for, who was studied, which test version was evaluated, and where reported performance came from.

• Galleri — Prescription-only multi-cancer early detection test.
• Oncoguard Liver — Blood-based aid for HCC detection in an at-risk surveillance population.
• Shield — Blood-based colorectal cancer screening test.

Performance is not a fixed property of a test. Reported results depend on study, population, stage or stratum, assay version and operating context.
