The aim of this prospective, observational, non-interventional, multi-centre study of the diagnostic use of DISQVER in neutropenic patients with FN is to provide further evidence of the efficacy of an NGS-based approach for detecting bloodstream infection in neutropenic patients.

The aim of this prospective, observational, non-interventional, multi-centre study of the diagnostic use of DISQVER (Platform for digital pathogen diagnostics from Noscendo GmbH) in neutropenic patients with FN (Febrile neutropenia) is to provide further evidence of the efficacy of an NGS (Next-generation seqzencing)-based approach for detecting bloodstream infection in neutropenic patients.
