By analyzing DNA methylation patterns in cerebrospinal fluid, the tool offers a minimally invasive alternative to traditional surgical biopsies.
This page surfaces every story mentioning liquid biopsy across our biotech coverage. We track each entity's appearance over time so readers can trace how the narrative evolves — which developments are isolated incidents, which build into longer arcs, and which reframe how operators in the space think about the entity. Story selection uses the same multi-source verification gate applied across the rest of our coverage.
Read our editorial methodology for how we identify, deduplicate, and score entity references. Our glossary defines the technical terms used across stories on this page, and our trends index contextualizes individual developments against the longer-running biotech beat. Cross-entity comparisons live on our compare view.
