Electronic interchange of lab test orders and results between laboratories reduces errors and gives full traceability.

Introduction of electronic lab test ordering and reporting corresponding results between laboratories when exchanging special tests for analysis in service labs, instead of manual paper based workflow, have reduced the fault rate by a factor 10 and reduced reporting time by 2 days compared to the manual workflow. Retyping orders and results into different IT systems is not longer needed as all 9 different labsystems in more than 60 laboratories are using the same standards and procedures resulting in full interoperability. The solution, challenges, implementation process and outcome is described in the paper.
