PART 1Executive Overview
1Definition

Liquid biopsies are non-invasive diagnostic tests that analyze blood or other body fluids to detect the presence of cancer-related biomarkers such as circulating tumor cells (CTCs) and cell-free DNA (cfDNA).

2Problem It Solves

They address the limitations of traditional tissue biopsies, which can be invasive, painful, and sometimes unavailable due to tumor location or accessibility.

PART 2Technical & Manufacturing
4How It Works

These tests work by isolating and analyzing CTCs and cfDNA from a patient's blood sample. The isolated genetic material is then sequenced and analyzed for mutations, genomic alterations, or other indicators of cancer.

5Materials Used
6Manufacturing / Creation Process

Manufacturing involves developing sensitive detection methods, such as cell isolation techniques (e.g., magnetic bead separation) and genetic sequencing technologies. These processes require specialized equipment and expertise in molecular biology and bioinformatics.

7Build Process

The build process includes sample collection, processing to isolate CTCs or cfDNA, amplification of DNA if necessary, sequencing, data analysis, and interpretation of results.

Circulating Tumor Cells (CTCs)
Cells that have detached from a primary tumor and entered the bloodstream, potentially leading to metastasis.
Cell-Free DNA (cfDNA)
Genetic material shed by cells into body fluids, which can include fragments of cancer-related DNA.
