New MALDI-TOF MS Microbiology Document

Wayne, Pennsylvania, USA—The Clinical and Laboratory Standards Institute has published the microbiology guideline Methods for the Identification of Cultured Microorganisms Using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (M58-Ed1).

Methods for the Identification of Cultured Microorganisms Using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (M58-Ed1) provides performance, reporting, and quality assurance recommendations for the identification of cultured microorganisms by microbiology laboratory professionals using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Recommendations for end-user verification and workflow integration are also included.

Features of this guideline include:

• The MALDI-TOF MS process, including selecting and preparing testing isolates
• Quality System Essentials for microbial identification using MALDI-TOF MS
• Supplemental information, including a quick reference guide and training and competence assessment checklist and form
