Postanalytisk

Postanalytisk is a term used in medical laboratory science to describe the post-analytical phase of testing, i.e., the activities that occur after laboratory analysis has been completed. In Danish, Swedish, and Norwegian contexts, postanalytisk refers to the final steps that convert analytical data into usable information for clinical decision-making. This phase encompasses result verification, interpretation, reporting, and communication, as well as data management and archiving.

Key activities in the postanalytical phase include the validation and release of test results, ensuring correct units and reference ranges, and adding clinician-oriented interpretive comments when appropriate. Critical value or panic value reporting is a central component, with defined policies for timely notification to responsible clinicians. Turnaround time goals are commonly established to ensure results are available when needed for patient care. Results are transmitted through laboratory information systems to electronic health records, and may be accompanied by notes, recommendations, or follow-up testing instructions.

Data management and documentation are essential in postanalytical work. Results are archived securely, amendments or corrections are recorded with audit trails, and standardized coding (such as LOINC or SNOMED) facilitates interoperability. Privacy and data integrity are maintained in accordance with regulatory requirements.

Quality and safety considerations in this phase focus on reducing miscommunication, transcription errors, and delays. Standardized reporting formats, clear interpretation guidance, and adherence to policies for urgent reporting help minimize post-analytical errors. Laboratories align with broader quality systems and accreditation standards, such as ISO 15189, CLIA, or CAP, to ensure consistent, reliable communication of laboratory findings and support optimal clinical outcomes.
