Can LOINC be defined as a Controlled Terminology?

Hi Joyce,

There is a free RESTful web service for this which can easily be implemented. See XML4Pharma LOINC Web Services
Also the NLM has a similar RESTful web service. See: MedlinePlus: MedlinePlus Connect: Web Service
I don’t think it makes sense to implement that as a physical file: there are over 73,000 LOINC codes.

I noticed you have a set of instructions for configuring MedDRA. But how would we add LOINC?

The example for the UNII dictionary only shows two columns. For LOINC it needs several variables whose values confer uniqueness to the row. For example, a row-uniqueness is usually determined by the combination of LOINC NUM, COMPONENT, PROPERTY, SYSTEM and METHOD.

Thanks

Joyce
