The College of American Pathologists (CAP) in a questionnaire-based survey of 727 laboratories in the USA, found that a significant proportion (63%) of respondents did not have written procedures for validation of immunohistochemical test of cytologic material. If the breakpoints routinely reported by the laboratory do not match CLSI, EUCASTor FDA, they are obsolete and must be updated to at least 2021 breakpoints before Jan. 1, 2024. The Clinical Laboratory Improvement Amendments (CLIA) regulate laboratory testing and require clinical laboratories . 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.

While this story serves as an example, it is not fiction. there are no evidence-based guidelines regarding valida-tion of immunohistochemical assays. They use terminology such as "accurate and reliable test system operation". <> Not reporting the drug MIC might be a preferable option to completing a verification or validation. Are the mucin cells clear of color (often seen as a pale blue color if you are using a Gill hematoxylin and/or are not doing a regressive stain)?
