Over-testing Galactomannan in patients with hematological malignancies: A retrospective analysis from a tertiary care
1Department of Clinical Microbiology and Infectious Diseases. Ondokuz Mayis University School of Medicine, Samsun, Türkiye.
Abstract:
This study aimed to evaluate the Galactomannan (GM) correlation with radiologic findings, treatment decisions and financial impact of over-testing. In this cohort, GM testing yielded a low diagnostic return, requiring 53 tests to obtain one positive result and 103 tests to identify a probable invasive aspergillosis (IA) case, generating a considerable avoidable financial burden. These findings highlight the need to rationalize GM utilization and align testing with IA risk to reduce hospital costs.
