postanalytik

Postanalytik, or the post-analytical phase, is the part of laboratory medicine that occurs after test analysis. It includes result verification, reporting, interpretation, and communication of results to clinicians, as well as the archival and management of data. The aim is to provide accurate, timely, and actionable information while safeguarding patient privacy and data integrity.

Key processes in the post-analytical phase include result release and authorization, where laboratory personnel review data for correctness and completeness, ensuring that reports contain patient identifiers, test names, units, reference ranges, and any interpretation or comments. Critical value notification procedures are defined to promptly alert clinicians when results indicate life-threatening conditions or require urgent clinical decisions. Reporting and communication involve delivering results through laboratory information systems, electronic health records, or secure messages, using standardized formats and codes to minimize transcription errors and ambiguity.

Interpretation support may be provided through automated flags, interpretive comments, and decision-support tools to help clinicians understand complex results or multi-test panels. Data management covers archiving, retention, retrieval of reports, audit trails, and compliance with privacy and data-protection regulations. Quality and safety focus on reducing post-analytical errors such as misreporting, misidentification, transcription mistakes, delayed release, or incorrect reference ranges, typically monitored through quality indicators and incident reporting.

Quality improvement efforts in the post-analytical domain emphasize standardizing report formats, harmonizing units and reference ranges, and ensuring efficient turnaround times. The post-analytical phase relies on integration with pre-analytical and analytical stages to form a complete and safe testing workflow within modern health-care information systems.
