Laboratories assign their own internal identifiers to each sample they receive for tracking through their LIMS. The labSampleId on an AnalyticalResult stores that identifier, providing a direct link to the lab's internal records. This cross-reference is essential during audits or when disputing a result — you can supply the labSampleId to the laboratory to retrieve the full internal analysis record, including QC data and chain-of-custody documentation not included in the deliverable file but needed for regulatory defense.
