Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to grading quality (or certainty) of evidence and strength of recommendations, the draft update reaffirms original recommendations but now categorizes 11 of the original 14 statements as Good Practice Statements, which indicates a high level of certainty, but a lack of direct, published evidence. This means that by Jan. 1, 2024, all breakpoints must be up-to-date, with breakpoints considered current as of 2021 (at a minimum).

Blood cultures are collected and sent to the microbiology laboratory, where microbiologists identify the organism causing the infection and set up susceptibility testing, the process by which the organism will be tested against antibiotics in varying dilutions to determine which dilutions prevent growth. Imagine that a patient presents to a hospital seeking care for a bloodstream infection. << Consider what could happen if your lab was sued based on the quality of your work and your employer had to go to court. For initial analytic validation of all laboratory-developed predictive marker assays (with the exception of HER2/neu, ER and PgR), laboratories should test a minimum of 20 positive and 20 negative tissues. endstream While this story serves as an example, it is not fiction. Can muscle be differentiated from collagen?
