About the Episode

This episode walks through the logic of Galleri® step by step: cfDNA isolation from the blood sample, generating methylation profiles by next-generation sequencing, the machine-learning classifier computing the score, and the origin prediction across 18 anatomic regions.

We also discuss why methylation is the target and the advantages of this approach.
