How does Epic ASAP interface with outside labs or systems?

• A. Through HL7/XML interfaces that transmit orders and receive results, aligning with workflows.
• B. By printing a paper order and faxing it.
• C. By manual data entry for every result.
• D. Through a REST API using JSON only.

Answer: (A)

Interoperability with outside labs is achieved through HL7-based interfaces that transmit lab orders to external systems and bring results back into Epic ASAP, often using XML encoding for the message structure. This standard setup lets the EMR send an order in a format the lab system can automatically receive, process, and return as structured data, which then maps directly into the patient’s chart and the clinician’s workflow. The benefit of HL7/XML interfaces is that they enable automated, bidirectional communication. Orders flow electronically to the lab, results come back and are automatically matched to the right patient and order, and the system can handle acknowledgments, errors, and routing according to established workflows. This keeps data consistent, speeds up availability of results, and reduces manual entry or paper-based steps. Printing and faxing, or entering every result by hand, are not electronic-integrated approaches and disrupt workflow with delays and higher error risk. A REST API using JSON only, while useful in other contexts, is not the standard method for the lab-order/results exchange described here, where HL7-based interfaces are the established mechanism between Epic ASAP and external labs.
