description: This profile defines the UK constraints and extensions on the International FHIR resource [Observation](https://hl7.org/fhir/R4/Observation.html), in order to represent an individual laboratory test and result value. These tests can be grouped together using the UKCore-Observation-Group-Lab profile.
