Vocabulary

A vocabulary is a terminology system that associates a code to a specific clinical event. One may distinguish two types of vocabularies:

Source vocabulary

The source vocabulary is the vocabulary used in the LIMS (Laboratory Information Management System) software. It is specific to the LIMS and may be different in each laboratory.

Standard vocabulary

The standard vocabulary is a unified vocabulary that allows data analysis on a larger scale.

• It is classified in chapter.
• It has a bigger granularity than the source vocabulary, multiple source codes may be associated to one standard code.
