This study is intended to determine the positive predictive value (PPV) and negative predictive value (NPV) of the multiprotein classifier based on the observed study prevalence of Non-Small Cell Lung Cancer (NSCLC) in the study participants.
Condition or disease
Patients must present with previously non-diagnosed lung nodules as found on CT. There is no change to the typical standard of care that any of the investigating physicians and/or centers provide the patients enrolled in this study. The data from this study will not be used to diagnose cancer nor be used to influence treatment decisions for the study participants.

Age ≥ 40 years
Smoking history: Never, Former, Current
Subject undergoing diagnostic evaluation for a lung nodule
Subject undergoing evaluation for a lung nodule by a pulmonologist, and/or by a thoracic surgeon
Baseline CT scan identifying lung nodule performed within 60 days of subject enrollment
Nodule(s) identified by CT scan previously not followed
Subject willing to provide informed consent for the collection of blood specimens
Nodule work-up at the time of enrollment eligibility indicates any prior attempted or completed diagnostic biopsy procedure, such as transthoracic needle aspiration, bronchoscopic biopsy or surgery

Current diagnosis of any cancer
Prior diagnosis of any cancer within 2 years of lung nodule detection, except for non-melanoma skin cancer
Administration of blood products, e.g. packed red blood cells, fresh frozen plasma, or platelets, within 30 days of subject enrollment
History of human immunodeficiency virus (HIV) or Hepatitis C
