This guide covers how to order laboratory tests and imaging studies using Medplum, from building order forms through tracking results. For the FHIR data model overview, see Labs & Imaging. For medication ordering, see the Medications section.
When a performing laboratory or imaging facility completes a diagnostic study, the results are represented in FHIR as a DiagnosticReport linked to individual Observation resources. This guide covers how results connect back to orders, how to structure them for display, and how to handle abnormal findings.
