The research that resulted in PExA began in 2004 and was conducted by Anna-Carin Olin, Professor in the Department of Occupational and Environmental Medicine at the University of Gothenburg’s Sahlgrenska Academy, which at the time examined workers exposed to various respiratory irritants and who went on to develop respiratory problems such as asthma and COPD.

Many workers developed work-related respiratory conditions, but the disease could not be identified using the examination methods available at the time. Some workers had increased levels of nitric oxide in exhaled air, which proved to be a marker of inflammation in the lungs in people with allergic asthma. However, it turned out that it was not a marker in people with any other type of asthma or COPD. It was on this basis that Anna-Carin Olin and her research team began working on looking for markers for different types of respiratory diseases.

Since its inception, around 35 Million SEK have been received in support from various research funds, such as the Heart and Lung Foundation, and through grants, loans and equity capital for commercial development.
