PExA

PExA develops, produces and markets a research instrument to study respiratory diseases such as asthma and chronic obstructive pulmonary disease, COPD.

It is a new non-invasive method for sampling of Respiratory Tract Lining Fluid (RTLF) from small airways. Small droplets, or particles, that arise when small airways close and re-open, are collected from the exhaled air and sampled by impaction. The method open-ups for quantitative and reproducible measurements of changes in the composition of the lining fluid from small airways in respiratory disease.

How PExA works

The method is like a blood sample for lungs, however it is not invasive. Lung diseases often begin with pathological changes in the small airways, but there is currently no non-invasive, user-friendly technology to measure the status in these sections of the lungs.
