PART 1Executive Overview
1Definition

Liquid biopsies are non-invasive diagnostic tests that analyze circulating tumor DNA (ctDNA) or RNA (circulating RNA) found in bodily fluids, such as blood. These tests can detect the presence of genetic material from tumors, enabling early disease detection and monitoring.

2Problem It Solves

Liquid biopsies address the limitations of traditional invasive biopsy methods by providing a less risky, more accessible alternative for early disease detection and monitoring. They can help identify cancer at an earlier stage when treatment is most effective, potentially improving patient outcomes.

PART 2Technical & Manufacturing
4How It Works

Samples of bodily fluid, typically blood, are collected from patients. The sample is then processed to isolate and analyze the DNA or RNA fragments present. Advanced sequencing technologies and bioinformatics tools are used to identify specific genetic alterations indicative of cancer or other diseases. This process allows for the detection and quantification of ctDNA or circulating tumor RNA (ctRNA) in a non-invasive manner.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves sample collection, processing, and analysis using advanced laboratory techniques. This includes blood draw, plasma isolation, DNA/RNA extraction, sequencing, and bioinformatics data analysis.

7Build Process

Samples are collected from patients through a simple blood draw. The blood is then centrifuged to separate the plasma, which contains circulating tumor DNA or RNA. These nucleic acids are extracted, amplified if necessary, sequenced using next-generation sequencing (NGS) technologies, and analyzed for specific genetic alterations.

14Glossary
circulating tumor DNA (ctDNA)
Genetic material from tumors that circulates in the bloodstream. It is used as a biomarker for cancer detection and monitoring.
circulating RNA
RNA molecules found in bodily fluids, often associated with cancer cells or other diseases. They can be used to detect specific genetic alterations indicative of disease.
next-generation sequencing (NGS)
Advanced DNA sequencing technologies that allow for rapid and accurate analysis of large volumes of genetic material, enabling the identification of specific genetic changes in ctDNA or RNA.
