The Science
THE SCIENCE
Percepta GCS was developed using RNA whole-transcriptome sequencing combined with machine learning.

Additionally, the Percepta classifier leverages novel "field of injury" science to identify genomic changes associated with lung cancer in current or former smokers. In current or former smokers with lung cancer, changes in gene expression exist throughout the airway - this is called the field of injury5. These changes occur as a result of damage due to smoke exposure which raises the risk of lung cancer 6.
