  • Reason
    As described in the equipment use manual (chapter 2, "results and interpretation", table 2), the vitek ms system can provide 03 types of identification results for the samples, depending on the confidence interval obtained. the myla software displays the results indicating the level of confidentiality. to consolidate the results, the identification of each sample is presented in a graphic and colored way: green square = good identification (means good confidence level and the system displays 01 identification as result); yellow triangle = low identification (means, low discrimination in the result.) the user will have several identification options as a result, so the user must do additional tests to obtain the final result of the identification); red circle = no identification (the system will show "no result" or "more than 04 identification results." the user must perform additional tests to obtain the result of the identification). a limitation of the vitek ms system has been identified: it may provide an incorrect identification result if the tested species are not included in the vitek ms equipment database. this is a system limitation for the entire maldi-tof database, which is not currently described in the system documentation. the vitek ms system is a system of identification of microorganisms that works based on a classification pattern of the species. the limitation verified in the system is due to the use of predictive modeling based on supervised learning. typically these types of models include an algorithm that learns certain properties of a set of data spectra (eg presence of peaks) to make these predictions. when the micro-organism tested is not part of the.
