Analytical Result Analysis Date

The analysisDate on an AnalyticalResult is the instrument run date — the moment the prepared extract or digest was measured in the lab. Piper uses analysisDate together with the parent SamplingEvent's sampleDate to check analytical holding times. Many methods specify maximum holding times between collection and analysis; if analysisDate is too far after sampleDate, the result may be flagged with a holdingTimeViolation. Compliance staff should review analysisDate for any result with a quality flag, especially when determining whether data from a delayed shipment can be used for regulatory reporting.
