Reference intervals were estimated using reflimR and refineR, and compared with IFU and direct RIs. Overlap between lower and upper limits was evaluated using a color-coded scheme.

The Working Group for Postanalytics of the Croatian Society of Medical Biochemistry and Laboratory Medicine has decided to describe the necessary steps in designing and monitoring quality indicators, with an emphasis on the quality of the postanalytical and post-postanalytical phase. The main purpose of these recommendations is to facilitate the incorporation of quality indicators into laboratories' daily routines. Laboratories in the Republic of Croatia are recommended to monitor three quality indicators in the postanalytical phase of laboratory work: turnaround time, withdrawn or retracted laboratory test reports, and notification of critical results. Additionally, two indicators are recommended in the post-postanalytical phase: monitoring issuance of laboratory test reports and monitoring user satisfaction.
