Safety Precautions 15 All samples, microbial cultures and inoculated products should be considered infectious and handled 16 appropriately. Aseptic technique and usual precautions for handling the bacterial group studied should 17 be observed throughout this procedure. Refer to "CLSI M29‐A, Protection of Laboratory Workers From 18 Occupationally Acquired Infections; Approved Guideline ‐ Current revision". For additional handling 19 precautions, refer to "Biosafety in Microbiological and Biomedical Laboratories ‐ CDC/NIH ‐ Latest 20 edition", or to the regulations currently in use in each country. 21 Do not use VITEK MS‐DS target slides after the expiration date. Before use, check that the packaging and 22 components are intact. Allow the VITEK MS‐DS target slides to come to room temperature before use.

Sample Preparation for Bacteria 29 NOTES: Powder‐free gloves should be used when handling VITEK MS‐DS target slides. Avoid touching the 30 spots on the slide. Handle the slide by the end of the slide. Do not write or mark on the slide. 31 Before adding samples to the VITEK MS‐DS target slide, place the VITEK MS‐DS target slide on a flat 32 surface, such as a silicone mat, that will prevent it from sliding. 33 The VITEK MS‐DS target slide used for the VITEK MS is the disposable VITEK MS‐DS target slide with 48 34 sample positions. This VITEK MS‐DS target slide is for single‐use only. The sample positions are divided 35 into three sections. Each section is called an acquisition group. The three small spots in the center of 36 each acquisition group must not be used for identification of microorganisms. These three small spots 37 are used for calibration 38
