The method includes detecting elevated levels of one or more carbonyl-containing volatile organic compounds (VOCs) that are biomarkers for lung cancer in exhaled breath from the subject specimen. The method may further include obtaining exhaled breath from the subject specimen; forming adducts of the carbonyl-containing VOCs with a reactive chemical compound; quantifying the adducts of the carbonyl-containing VOCs to establish a subject value for each of the adducts; and comparing each subject value to a threshold healthy specimen value for each of the adducts of the carbonyl-containing VOCs. One or more subject values at quantities greater than threshold healthy specimen values are also useful for screening for lung cancer in the subject specimen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noninvasive detection of lung cancer using exhaled breath","description":"A non-invasive method of detecting or screening for lung cancer in a subject specimen is provided.
