• PExA's noninvasive lung sampling showed shared protein signals with invasive bronchoalveolar lavage in an Australian study of three silicosis patients.
• Matched samples shared 343–688 protein analytes per participant, with signal correlations ranging from 0.48 to 0.71.
• Of 162 protein analytes detected in all three noninvasive samples, 131 (81%) appeared in all three lavage samples.
• The overlap was four times greater than expected by chance, supporting the technique's ability to capture biologically relevant small-airway information.
• The findings strengthen the technology's scientific basis for biomarker discovery and drug development, supporting broader commercial research applications.
