How MALDI-TOF Identifies Organisms
- MALDI-TOF creates a protein 'fingerprint' to ID organisms rapidly using laser desorption and time-of-flight measurement.
- Its database-matching approach improves with more data, increasing accuracy over time.
Use MALDI-TOF To Speed IDs
- Use MALDI-TOF to cut identification time from ~18 hours to under an hour for colony identification.
- Prioritize it for blood-culture-derived colonies to speed clinical decision-making.
Low Running Costs And Streamlined Workflow
- MALDI-TOF has low consumable costs and simplifies lab workflows by replacing many biochemical tests.
- This consolidation reduces validation burden and long-term running costs despite high initial equipment expense.
