Diagnostic - Laboratory

Reference

  1. openEHR Laboratory analyte result

Overview

A Laboratory Analyte Result carries a single measured/detected substance (analyte) from the analytical phase of testing through to the Observation referenced by DiagnosticReport.result. See BCR-ABL Monitoring for a worked use case of this profile - BCR-ABL1 quantification for chronic myeloid leukaemia (CML) monitoring, from a Cepheid-class ASTM-communicating analyser through to iGene.
