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.

Data Mapping

Laboratory Analyte Result

Rows marked with ↳ in the Data Element column are sub-elements of the Result row above them, i.e. they map to fields on the Observation referenced by DiagnosticReport.result.

Result Detail

These entries are expressed in Observation.component - see BCR-ABL Monitoring for a worked example.
