Utility of (1–3)-β-d-Glucan Testing for Diagnostics and Monitoring Response to Treatment During the Multistate Outbreak of Fungal Meningitis and Other Infections

Our data suggest that measuring BDG in CSF is a highly sensitive test for diagnosis of fungal meningitis in this outbreak. Analysis of BDG levels in serially collected CSF demonstrated that BDG may correlate with clinical response. Routine measurement of BDG in CSF may provide useful adjunctive data for the clinical management of patients with outbreak-associated meningitis.
