Prior to staining patient tissue, you will need to test the staining protocol(s) to make certain that the stain quality that the new instrument is providing is acceptable for diagnosis. For example, updating carbapenem breakpoints for the Enterobacterales is considered a top priority, as the adverse clinical and public health outcomes associated with not doing so are significant. 3. xwTS7PkhRH
