Liquid biopsies are a set of minimally invasive diagnostic methods that analyze tumor-derived materials that can be found circulating in biological fluids, to provide information for the diagnosis, treatment, and monitoring of cancer. While tissue biopsies and imaging techniques remain the current standards of care in the diagnosis of solid tumors, they have risks and limitations and limitations, some of which can be overcome by the use of liquid biopsy in clinical oncology, as an alternative or complementary technique to the current standards of care.

The liquid biopsy market is expected to surpass $1.5 billion by 2023, according to our latest report,  World Market for Liquid Biopsy, 2018-2023. 

As of 2019, over 40 companies are active in the global market for liquid biopsy diagnostics and monitoring tests. The market for liquid biopsy testing, still in its infancy, is rapidly evolving as vendors develop and commercialize innovative new technologies to meet the needs of the clinical diagnostic market. Demand is also growing swiftly, at a projected CAGR of 27.9% over the next five years, as patients, clinicians, and payors increasingly accept liquid biopsy as an alternative or complementary procedure to traditional tissue biopsies.
