Laboratories run samples in analytical batches, each with associated quality control samples such as method blanks, matrix spikes, and duplicates. The labBatchId on an AnalyticalResult links the measurement to that QC batch. If a lab later discovers a QC failure in a particular batch — for example, a contaminated blank — you can identify all AnalyticalResults sharing the same labBatchId that may be suspect. This batched traceability is a fundamental part of data usability reviews required by many environmental regulatory agencies before monitoring results are submitted.

Analytical Result Lab Batch ID
The `labBatchId` on an AnalyticalResult identifies the instrument analysis batch within which the laboratory processed this sample alongside its QC samples.
