The Oregon ELR Project

About Electronic Laboratory Reporting

Historically, communicable disease reporting to state and county health departments was paper-based, relying heavily on FAX, telephone and snail mail. Today's sophisticated laboratory information systems bring an opportunity to move toward more timely and efficient electronic laboratory reporting. ELR data are critical to Public Health disease surveillance programs and thus to population health.

The Oregon ELR Project provides a one-stop drop-off point for laboratories to submit reportable data using electronic data interchange. In this system, the Public Health Division functions as an electronic hub to accept, route, and process electronic HL7 messages containing lab and clinical data.

ELR Legally Mandated for High-Volume Laboratories


  • Oregon's HL7 2.5.1 ELR Implementation Guide (pdf). For a comprehensive guide on ELR message construction, visit
    • NEW!! This guide is being revised to align with CDC guidance for COVID-19 AOE requirements. We are doing our best to keep this up to date. For official guidance, please see CDC's How to Report COVID-19 page.
    • HL7 2.5.1 is the only acceptable standard for meeting Promoting Interoperability requirements.
    • While Oregon supports HL7 2.3 messages, we encourage submitters to adopt the 2.5.1 standard. For earlier versions, please visit
  • We understand that not all sites are prepared to submit HL7 data for reporting, especially those sites doing only Point of Care tests for blood lead and COVID-19. We will accept data that conform to Oregon's CSV ELR Implementation guide (pdf) with approval from our onboarding team.
    • This template (last updated Aug 2020) may be used to help you construct your message. All columns are required to be present even if not populated.

Tools and Standards

  • Logical Observation Identifier Names and Codes (LOINC®) for specific laboratory procedure names
  • Systematized Nomenclature of Medicine (SNOMED®) for descriptions of findings, specifically for organism names
  • Reportable Condition Mapping Tables (RCMT) for mapping between reportable conditions, LOINC test codes, and SNOMED result codes.

Public Health Promoting Interoperability (aka, Meaningful Use)

ELR is a required Promoting Interoperability (formerly, Meaningful Use) measure for Eligible Hospitals in Oregon. To meet MU requirements, laboratory data must be sent from an ONC certified EHR (which usually includes Laboratory Information Systems (LIS)). Read more about Oregon Public Health Meaningful Use...
