What is a
liquid biopsy?

Liquid biopsy is a technology for predicting disease by detecting or analyzing the concentration of disease-related biomarkers present in samples such as blood, urine, and saliva. Liquid Biopsy, a non-invasive alternative to tissue biopsy, can help determine cancer treatments by identifying clinically relevant biomarkers. Representative circulating biomarkers used in liquid biopsy include circulating tumor cells (CTCs), exosomes, and circulating tumor DNA (CtDNA).

Tissue Biopsy vs Liquid Biopsy

The biggest advantage of liquid biopsy is its convenience. Liquid biopsy does not require painful
tissue biopsy to directly remove a patient's tissue, and can confirm the presence of disease with only body fluid.

Tissue Biopsy

Invasive
long term (surgery)
Resection/Incision (Risk)
Some patients or tissues are not available
Limited lesion tissue

Liquid Biopsy

Non-Invasive
Short time (small amount of blood)
Blood collection (convenience)
Most patients can be tested
All tissue
