Ethical StatementThe work was ethically approved by the East London & the City Local Research Ethics Committee (REC reference number 05/ Q0603/6 and, as amended on 28 October 2009, reference ReDA 003933 QM). All patients in the Barts study cohort gave informed written con- sent. BAL fluid samples from the Innsbruck University Hospital were obtained during routine diagnostic investigations and analyzed anony-mously. This study was approved by the local ethics committee, Medical University Innsbruck (UN4529/308/4.1).

Disease Introduction MechanismInvasive fungal disease (IFD) is a major cause of infectious mor- tality in hemato-oncology patients due to their underlying dis- ease and its treatment, which lead to periods of prolonged immu- nosuppression. Invasive pulmonary aspergillosis (IPA) is the most common cause of mortality due to mold disease, and early diagnosis and treatment are vital for improving outcomes. However, early diagnosis is hampered by the limitations of current biomarker tests and a lack of consensus on the best sam- ples to be tested (i.e., blood, bronchoalveolar [BAL] fluid, or tissue biopsy specimens) in terms of both test sensitivity and practica- bility. Direct examination or culture of pulmonary tissue remains the “gold standard” for the diagnosis of IPA.
