Artificial intelligence (AI) and machine learning gather information without filtering or expert supervision and translate it into medical instructions or prescriptions. The language used in “standards” or “guidelines” is therefore becoming increasingly important. We extracted VIM3 correspondence of glossaries from a selection of CLSI documents, noting language anomalies and inconsistencies. Having a hierarchy of sources can help reduce ambiguities.

Nuova definizione di incertezza delle misure e conseguenze per il laboratorio medico

https://doi.org/10.23736/S1825-859X.25.00313-5

Joint Committee for Guides in Metrology today presents a definition of measurement uncertainty that corrects the previous one and improves the management of scenarios other than scalar (quantitative) measurements, such as classificatory or qualitative (nominal and ordinal) properties. Nominal results are often found in biology and medicine. For the accreditation of medical laboratories and testing laboratories, both ISO 15189 and ISO 17025 require the management of these situations, using the professional expertise of specialists, with the support of systems and consumables manufacturers. ISO produces detailed guides for this purpose, such as ISO 20914, ISO 27877, ISO 16393, ISO 20397-2, and ISO 22692. Laboratories now have all the tools they need to meet accreditation requirements. The SIPMeL Q16 Recommendations are confirmed and reinforced.

The Joint Committee for Guides in Metrology (JCGM) today presents a definition of measurement uncertainty that modifies the previous one and improves the management of scenarios other than scalar (quantitative) measurements, such as classificatory or qualitative (nominal and ordinal) properties. Nominal results are often found in biology and medicine. For the accreditation of medical laboratories and testing laboratories, both ISO 15189 and ISO 17025 require the management of these situations, using the professional expertise of specialists with the support of manufacturers. Some of the members of JCGM WG2 developed a discussion on the concept of measurement uncertainty and raised some criticisms. ISO produces detailed guides for this purpose, such as ISO 20914, ISO 27877, ISO 16393, ISO 20397-2, and ISO 22692. Laboratories now have all the tools they need to meet accreditation requirements on uncertainty.

Controllo di qualità interno: divergenze tra raccomandazioni IFCC, standard ISO e raccomandazioni SIPMeL

IFCC produced a Recommendation that claims to be inspired by ISO 15189:2022 but diverges from it in many places: in the glossary, in the general principles, where it introduces commutability and known values of control materials, on the objectives of IQC, not compatible with statistical rules, on control materials with commutability, in the case of control lot change or reagent change. IFCC introduces the case of multiple instruments, absent in ISO 15189:2022. IFCC proposes control repetition, absent in ISO and disapproved by subject matter experts, does not follow CLSI C24 guidance for estimation of imprecision and expected value with which to construct control rules and charts. IFCC, in addition to statistical rules and Sigma metrics, adds the additional criterion of clinically acceptable limits, without providing the scientific basis. IFCC diverges from bibliographic sources and ISO 15189:2022 on the moving average of patient and repeat patient samples, as on the mixture (pool) of patient samples, as well as on “sentinel” examinations. IFCC never considers CLSI C24 guidance. IFCC supports the comparison between instruments despite multiple critical points, contained in the references cited by IFCC too. IFCC does not correctly describe the difference between measurement uncertainty and total allowable error.
