ISO 15189:2012 establishes the requirements for clinical sample management, ensuring quality of process and laboratory information management. The accreditation authority, ENAC in Spain, established the requirements for the authorized use of the label in reports issued by accredited laboratories. These recommendations are applicable to the postanalytical processes and the professionals involved. The Standard requires laboratories to define and document the duration and conditions of sample retention. Laboratories are also required to design an internal quality control scheme to verify whether postanalytical activities attain the expected standards. Information management requirements are also established and laboratories are required to design a contingency plan to ensure the communication of laboratory results. Instructions are finally provided about the correct use of the accreditation label in laboratory reports. A range of nations and scientific societies support that clinical laboratories should be required to obtain accreditation. With ISO 15189 being the most specific standard for demonstrating technical performance, a clear understanding of its requirements is essential for proper implementation., Competing Interests: Competing interests: Authors state no conflict of interest., (© 2021 Mᵃ Libòria López Yeste et al., published by De Gruyter, Berlin/Boston.)
