Liquid biopsy in cancer

spotlight topic:

Molecular, genetic and genomic biomarkers

Cell free DNA and next generation sequencing

Published 29 May 2025

These tests use genetic sequencing to look for changes in the cell free DNA such as mutations, including single nucleotide polymorphism (SNP) copy number variations (CNV), which may be associated with particular types of cancer.
