What Exactly is Liquid Biopsy Testing About?

Liquid biopsy is a minimally invasive diagnostic technique that detects biomarkers, such as circulating tumor cells, cell-free DNA, RNA, and proteins, in bodily fluids such as blood or urine. Unlike traditional tissue biopsies, which require invasive procedures, liquid biopsy offers a non-invasive alternative for monitoring and diagnosing various conditions, particularly cancer. Through analyzing genetic material shed by tumors into the bloodstream or other bodily fluids, liquid biopsy enables early detection, monitoring of treatment response, identification of genetic mutations, and assessment of disease progression. This approach holds promise for personalized medicine, facilitating targeted therapies and improving patient outcomes through timely intervention and tailored treatment strategies.
