Conclusion:

Induced sputum samples were processed to collect single cell suspensions while removing debris through filtration. Sputum samples can be analyzed by flow cytometry while contaminating squamous epithelial cells (SECs) can be excluded from further analysis with the inclusion of a viability dye. Two macrophage populations were identified, and morphologies confirmed by sorting experiments, that can serve as verification that the sample was obtained from the lung as opposed to being saliva. We determined at least 0.75 million cells are needed for reliable analysis. The use of flow cytometry to analyze sputum-derived cells serves as a reliable, non-invasive means to monitor the health status of the lung.
