What is an example of a pre-analytical error?

Pre-analytical errors occur before the actual testing begins, during steps like specimen collection, transport, and handling. Mislabeling a specimen is a classic example because the error happens before any analysis is performed, potentially sending the wrong sample to the lab and producing incorrect results for the patient. Errors during analysis involve the testing process itself, such as instrument malfunctions or issues with the assay. Data entry errors occur after results are generated, during transcription or reporting, which is post-analytical. Calibration errors relate to preparing and validating the instrument, typically part of the testing process rather than the pre-analytical phase.
