The incidence of IFD correlated directly and significantly (x2 p=0.0005) with risk stratification group: highest proportion in the high-risk group. ?Since all the biomarkers have inherent limitations, a better diagnosis yield is achieved combining the biomarkers. ? All three biomarkers share high negative predictive value and can exclude reasonably IFD in haematology adult patients treated with wide spectrum antifungals.;Evaluation of two serologic test for diagnosis invasive Aspergillosis C. Castro, A. Romero, A. Aller, T. Gonzalez, A. González, E. Martín-Mazuelos H. U. Valme, SEVILLA, Spain;A total of 236 sera from 51 patients in risk of IA were tested for GM using Platelia Aspergillus kit (Bio Rad, France) which 36 sera (10 patients) were tested for BG also using Fungitell kit (Associates of Cape Cod., USA). Patients were attended at the University Hospital of Valme from Seville from January of 2008 to December 2008. Patients with GM index ≥0.5 in two consecutive samples have been marked as GM
