| Cohort | From April 2016 to March 2018 (24 months), 41 pediatric patients treated at the University Children’s Hospital Würzburg were screened twice weekly by GM and PCR-based diagnostic assays. All available patients with more than two serum samples and existence of frozen backup samples (n = 26) were selected for retrospective BDG analysis. Patients (12 males, median age of 11.5 years (range, 2 to 19 years); 14 females, median age of 8.5 years (range, 2 to 18 years)) were all eligible and in preparation for alloSCT. |

| Disease Introduction Mechanism | (1→3)-beta-D-Glucan (BDG) is a fungal cell wall component released into patients’ blood during invasive fungal disease (IFD). BDG is not specific for Aspergillus infection, and could therefore be used as a broad spectrum fungal biomarker keeping in mind that it is not detectable in IFD caused by mucormycetes, Cryptococcus or Blastomyces dermatitidis. Confounding factors leading to false positivity include bacteremia and various intravenous medications. |
