PART 1Executive Overview
1Definition

Liquid biopsy is a minimally invasive technique for detecting circulating tumor DNA (ctDNA) or RNA (ctRNA) in blood samples. It enables the early identification of cancer by analyzing small fragments of genetic material shed from tumors into the bloodstream.

2Problem It Solves

Addresses the limitations of traditional biopsy methods by providing a non-invasive alternative that can be repeated over time, reducing patient discomfort and invasiveness.

3Lifecycle / Journey Stage
early commercial
PART 2Technical & Manufacturing
4How It Works

The process involves drawing a patient's blood sample, which is then processed to isolate and sequence ctDNA or ctRNA. Bioinformatics tools are used to analyze these sequences for mutations indicative of cancer. This allows for both early detection and continuous monitoring of disease progression or treatment efficacy.

5Materials Used
6Manufacturing / Creation Process

Involves the development of advanced sequencing technologies, sample preparation kits, and bioinformatics software. The manufacturing process requires precise handling to ensure the integrity of genetic material during extraction and analysis.

7Build Process

The build process includes steps such as blood collection, plasma isolation, ctDNA/ctRNA extraction, library preparation for sequencing, and data analysis using sophisticated algorithms.
