PART 1Executive Overview
1Definition

Liquid biopsy is a non-invasive diagnostic technique that involves analyzing circulating tumor cells (CTCs) or cell-free DNA (cfDNA) from a patient's blood to detect the presence and characteristics of cancer.

2Problem It Solves

Liquid biopsy addresses the limitations of traditional tissue biopsies by providing a non-invasive alternative that can be performed more frequently, leading to better patient outcomes through early detection and personalized treatment plans.

PART 2Technical & Manufacturing
4How It Works

The process typically involves collecting a small volume of blood, which is then processed using various techniques such as filtration, magnetic sorting, or microfluidics. The isolated CTCs or cfDNA are then analyzed for specific genetic markers or mutations associated with cancer. This allows for the identification and monitoring of cancer progression in real-time.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves developing and optimizing techniques for blood sample collection, processing, and analysis. This includes the design and production of microfluidic devices or filtration systems, as well as the development of assays for detecting specific genetic markers.

7Build Process

The build process starts with the selection of appropriate technologies for sample preparation and analysis. This is followed by rigorous testing to ensure accuracy and reliability. The process also involves creating databases of known cancer mutations and developing algorithms for interpreting the results.

14Glossary
circulating tumor cells (CTCs)
Cells that have detached from a primary tumor and entered the bloodstream, which can be analyzed for cancer characteristics.
cell-free DNA (cfDNA)
DNA fragments found in the blood plasma or serum, often derived from dying cells, including cancer cells.
microfluidics
A technology that deals with the control of fluids at the microscale, used to manipulate and analyze small volumes of liquid samples.
