Microbiology Identification
Typical Use
Rapidly identify bacteria and fungi from colonies using proteomic fingerprinting.
Description
A matrix assisted laser desorption ionization time of flight mass spectrometer that analyzes protein spectra from cultured colonies to provide rapid, accurate species level identification of bacteria and fungi within minutes, transforming clinical microbiology workflows by reducing time to identification compared with biochemical methods. MALDI TOF requires cultured isolates, validated reference libraries, and quality control procedures to ensure reliable identification, and it is often paired with rapid susceptibility testing methods for comprehensive pathogen characterization. Adoption of MALDI TOF improves laboratory efficiency, supports targeted therapy, and reduces time to appropriate antimicrobial selection, but requires investment in instrumentation, database maintenance, and trained personnel.
