Standardization makes readings from different sources comparable when their meaning and units match. It runs offline and needs no model API key.

​
Names, codes and units

  • Measurements use the bundled LOINC vocabulary.
  • Reported symptoms and diagnoses use separate ICPC-3 lookups.
  • Units are normalized to UCUM; conversions require compatible dimensions.
  • Multilingual aliases can resolve to the same concept. An unknown or ambiguous name can remain unresolved.
Passing the original unit is important: it can affect which code represents a reading. Similar labels do not guarantee the same clinical meaning.

​
Python example

Use the original value and unit when standardizing a complete reading. For document extraction and library examples, see the quickstart.

​
Scope

The bundled vocabulary covers selected laboratory and clinical observations, not every LOINC concept or vendor score. Incompatible units are not silently converted, and an unresolved name does not receive a guessed nearest code. You can inspect the corpus identifier through mirobody.BUNDLE_VERSION. Vocabulary coverage, licensing and mapping rules are documented in the standardization reference.
