How could these new Guardant360 Liquid applications affect Guardant Health’s market opportunity?

The five added tools widen Guardant360 Liquid’s reach into breast and lung cancers where traditional genomic markers are missing or unclear.

What should investors watch next to gauge whether this epigenomic expansion is working?

The clearest signal is how much of Guardant Health’s Guardant360 Liquid oncology revenue mix management attributes to epigenomic applications in upcoming quarterly reports. Investors can track whether usage linked to InfinityAI and these breast and lung cancer predictors grows fast enough to influence the firm’s US$1.36b to US$1.37b 2026 revenue guidance over time.
