Sponsored by Oslo University Hospital · Observational
The project aims to increase the diagnostic accuracy in occupational asthma (OA), with emphasis on Irritant Induced Asthma (IIA). Currently, most patients are evaluated in occupational medicine by comparing the exposure and symptom characteristics with epidemiological data. Biological markers may be present in AA, but presently not in IIA. The majority of cases evaluated are considered as possible IIA, i.e. low-dose multiple exposures. VOC features will be analyzed with the Breath Biopsy® and TD-GS-MS (Owlstone Medical Ltd, UK).
3,921 studies on the registry are indexed under Asthma; 507 are open to participants now.
This study's planned enrollment of 80 is below the median of 150 across 970 observational studies indexed under Asthma.
