Non-invasive Diagnosis of Invasive Pulmonary Aspergillosis by Use of Biomarkers in Exhaled Breath Condensate

The EBC will be collected by use of the RTube(R) system which is commercially available for the purpose of collection of EBC. As the patient breathes through a mouth piece, the exhaled breath is lead through a cooling chamber where the vaporous part of the exhaled breath condenses. The investigators aim at collecting a total minimum of 3.0 mL EBC per study participant in order to have sufficient amount of protein for the subsequent analysis.
