Different laboratories may report the same analyte in different units — micrograms per liter vs. milligrams per liter, for instance. The normalizedValue on an AnalyticalResult converts the resultValue to a consistent normalizedUnit so that results from different labs and reports can be compared directly and plotted on the same trend chart. Exceedance detection uses normalizedValue and normalizedUnit to compare against ThresholdValue limits, ensuring the comparison is always in the same unit regardless of how individual labs expressed their measurements.

Analytical Result Normalized Value
The `normalizedValue` on an AnalyticalResult is the concentration expressed in a standard unit after unit conversion from the lab's original reportedUnit.
