Exceedance Threshold Value

The thresholdValueId on an Exceedance pinpoints the specific analyte limit — not just the regulatory program — that the result violated. Following this reference lets compliance staff retrieve the exact thresholdValue, thresholdUnit, and direction that were used in the comparison, along with the source citation for that limit. This level of specificity is essential for regulatory notifications, which must cite the precise standard exceeded rather than just the general regulatory program referenced by the thresholdSetId.
