Unit Normalizer

The Unit Normalizer converts incoming units to UCUM canonical form so the same analyte is comparable across hospitals and instruments.

mg/dL vs mmol/L

Clinicians may still see hospital-preferred units in the portal; storage and flag thresholds use normalised UCUM internally.

Behaviour

  • Runs synchronously before Observation Repository writes.
  • Unknown unit mappings queue for steward review — never silent guess on panic paths.
  • Shares vocabulary tables with the Terminology Service.
