Front-end automation covers the pre-analytical steps that prepare specimens for testing. The best description is that it receives and collects samples, processes them, timestamps, and centrifuges. This captures the key tasks of logging and accessioning specimens, applying necessary processing, marking the time of handling, and performing centrifugation to prepare samples for analysis. The other activities happen later in the workflow: final result verification occurs after testing as a post-analytical quality check; data archiving is about storing results and records; validating instrument calibrations is part of instrument QA and maintenance, not pre-analytical preparation.
