The body to record the following information: A statement which says: This protocol has been validated and is approved for patient use. This time, the interpretation of the MIC is resistant. 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 recommendation does not apply to any marker for which a separate validation guideline already exists. endobj << Explain how statistics is applied to validate a new method. Laboratories may choose to validate breakpoints that are not FDA-cleared due to clinical relevance or local needs.
