HL7 Laboratory Order & Result Interface (LOI & LRI) Implementation Guides - May 2018

Date: October 29, 2018

The Laboratory Order Interface (LOI) and Laboratory Results Interface (LRI) are HL7 Implementation Guides for creating a HL7 Version 2.5.1 OML^O21 message for laboratory test orders and results, respectively. HL7 Workgroups have created cohesive LRI and LRI Guides specific to the NBS reporting requirements. As of August 2017, these draft profiles are being balloted, with final publication anticipated in late August or early September. These profiles will be of significant value to laboratories that are implementing NBS orders and results.

The ballot versions of both Guides are on the HL7 ballot web site. Note that you will need to create a free HL7 account to download these documents.
