For instances where clinical/demographic information for the related person are required and they are not included within testing, a Patient resource for the related person SHOULD be included, with the Patient.link field referencing the RelatedPerson resource for the same individual. Elements duplicated across both the Patient and RelatedPerson for the same individual SHOULD in this case be captured within the Patient resource only. The RelatedPerson resource then references the proband Patient resource through the RelatedPerson.patient field. For instances where demographic information is not required, e.g. where details regarding clinical pedigree only are required, and the relative if not part of testing, the UKCore-FamilyMemberHistory resource SHOULD be used instead. For Duo/Trio scenarios, RelatedPerson resources should be added to the supportingInfo field for the Consultand request, with links from the related person following the same pattern as above." /> <copyright value="Copyright © 2026+ NHS England Licensed under the Apache License, Version 2.0 (the \\\"License\\\"); you may not use this file except in compliance with the License.
