This studyis designed to look at the effectiveness of a new technology call Nanotechnology Biomarker Tagging (NBT) in detecting COVID-19 infection using breath samples of patients. Participation in this study is expected to take less than one month and will consist of a breath sample being taken by the research team, a cheek swab being taken by the research team, a questionnaire that will be completed by the participant with the help of the research teams, and a review of your medical record.

The main objective of this study is to analyze sputum collected from the residue remaining from bronchoalveolar lavage (BAL) procedures to compare the cellular characteristics of BAL samples to those of sputum samples collected from the acapella® airway assist device. We intend to enroll volunteers who are being evaluated by an MUSC pulmonologist as part of their standard medical care. The Control Sputum sample will be collected by volunteers at home over a three day period using an acapella® airway assist device. The cellular profiles of the BAL and sputum samples will be analyzed by flow cytometry. Active participation in this study is expected to last less than one month and will be complete once a sample is obtained from the BAL procedure.

This is an observational study that will analyze electronic health records data from real-world populations and settings in order to fully characterize the outcomes of Lung Cancer Screening with Low-Dowse CT scans.

The primary objective of this study is to develop a blood-based gene expression signature, known as the ONC-LN-04 Lung Test, to be used in the detection of lung cancer in patients who underwent radiologic screening for lung cancer and had lung nodules detected. We intend to enroll volunteers who are being evaluated by a Medical University of South Carolina (MUSC) pulmonologist as part of their standard medical care. Participants will be current or former smokers, who have either (a) radiologic evidence of lung nodules, or (b) a confirmed diagnosis of non-small cell lung cancer (NSCLC) and has not undergone surgical excision, chemotherapy or radiation therapy for this malignancy. A single blood sample will be obtained from willing participants, then stored and analyzed for measurement of gene expression and development of the ONC-LN-04 test. Active participation in this study will be over once a blood sample is obtained; however, we may need access to participants' medical records post-enrollment and sample collection in order to monitor medical outcomes. Review of participants' medical records will occur until up to approximately 3,500 subjects have been enrolled and have provided clinical information and a blood sample.
