Interpretation

Method

Microorganism Identification by Matrix Assisted Laser Desorption Time of Flight Mass Spectrometry (MALDI-TOF MS):

Microorganisms are identified by MALDI-TOF MS with the Bruker MALDI Biotyper®. The MALDI Biotyper® generates a unique protein spectrum of a microorganism. The protein spectrum is matched to curated databases of reference spectra to generate an accurate genus or species-level identification.

This test was developed and the performance characteristics determined by the University of Washington Department of Laboratory Medicine. It has not been cleared or approved by the US Food and Drug Administration. This test is used for clinical purposes. It should not be regarded as investigational or for research. This laboratory is certified under the Clinical Laboratory Improvement Amendments (CLIA) as qualified to perform high complexity clinical laboratory testing.
