Divergences between IFCC recommendations for internal quality control and ISO standards

The Task Force on Global Lab Quality of the International Federation of Clinical Chemistry and Laboratory Medicine published its Recommendations on the topic of IQC, stating that they are derived from the ISO 15189:20222 standard. TF-GLQ deviates in several places from ISO 15189. Some references to CLSI documents are incorrect. Laboratories and Accreditation Bodies, however, may not deviate for the requirements of ISO 15189 from the original text of the ISO standard and the guides that remain compliant with it.
