Electronic Laboratory Reporting (ELR)


CDPHE is currently accepting new feeds for electronic laboratory reporting (ELR) from hospitals.  ELR provides advantages to hospitals other than Meaningful Use attestation, including improved efficiency due to reduced manual entry for laboratory technicians and infection control professionals and increased timeliness and completeness of reporting, which improves health outcomes and reduces time required to follow-up and complete case reports.

Implementation Overview

The information on this page is meant as an overview. More detailed information on implementation can be found in the CDPHE Electronic Laboratory Reporting Implementation Guide pdf file .


ELR On-boarding Process:




Step Name





Laboratories wishing to on-board for ELR must register their intent to attest should complete the Meaningful Use Registration Form. Or, if labs are wishing to on-board for ELR but not attest for Meaningful use, they should declare this intent via email to the ELR Coordinator: CDPHE_ELR@state.co.us



The on-boarding laboratories will review the vocabulary and messaging standards and reporting requirements. They will generate and validate test messages using a standard tool, submitting the results to CDPHE.


Initial Submission

Once your agency is ready to generate messages with the required standards, a test message will be sent using one of the secure methods. This HL7 message will be validated by CDPHE.  Completion of Step 3 meets Meaningful Use Stage 1 attestation requirements.


In Queue

If the laboratory is ready to submit on-going results, but CDPHE is not prepared to perform the validation, the laboratory may be placed on a wait-list for on-going submission and validation.  Facilities placed in the queue can attest for Meaningful Use Stage 2, if that is their goal.



Once your HL7 message has been validated and a secure method of transfer has been successfully tested, on-going production level data will be transferred from your system on at least a daily basis (weekdays only).  These messages will be evaluated for vocabulary standards.  The reports received will be matched against disease reports received from your facility from traditional methods.


Production & On-going Validation

Once CDPHE is satisfied that your decision engine is appropriately flagging and reporting all reportable conditions, we will certify your feed and move your ELR feed into production.  At this time, your facility can cease its previous method of reporting conditions based only on a laboratory results.

Note: On-boarding facilities should give themselves 9 – 12 months to complete this process.

Messaging and Vocabulary Standards:

Standards for new feeds are the same as Meaningful Use Stage 2 requirements:

Messaging Standard:

HL7 2.5.1






Note that for Meaningful Use Stage 1, HL7 2.3.1 is acceptable and SNOMED CT is not required.
