A liquid biopsy is a simple and non-invasive alternative to surgical biopsies that allows doctors to learn about tumors from a simple blood sample. In 1994, scientists advanced to the point where they could detect specific mutations in ctDNA. Dennis Lo discovered fetal cfDNA in the blood in 1997, and Veridex released the first commercially available liquid biopsy assay, the CELL SEARCH CTC test, in 2000.
