Percepta Nasal Swab
Use
The Percepta Nasal Swab test is a non-invasive genomic test designed for assessing lung nodules in patients with a history of smoking. It utilizes whole-transcriptome sequencing and machine learning to detect genomic changes in nasal epithelial cells, aiding in lung cancer risk assessment. The test helps physicians provide better care by identifying patients at low or high risk of lung cancer, potentially reducing unnecessary invasive procedures for low-risk patients and supporting timely interventions for high-risk patients.
Special Instructions
The test involves a simple, in-office nasal brushing for non-invasive sample collection. It provides actionable results and evidence-based guidance for risk stratification, allowing physicians to make informed decisions and reduce unnecessary procedures.
Limitations
The test's limitations include its reliance on genomic changes detectable in nasal epithelial cells, which may not be as comprehensive as tissue-based assessments. It is designed for patients with a history of smoking and may not be applicable to non-smokers. Additionally, the test's predictive values are based on a population with a 25% cancer prevalence, which may not reflect all clinical settings.
