CodeSystem: Immunological Data Component Codes (Experimental)

Official URL: https://hl7.eu/fhir/ig/hl7.eu.fhir.protect-child/CodeSystem/imm-data-component-cs Version: 0.1.0-ci-build
Draft as of 2026-08-11 Computable Name: ImmDataComponentCS

Local component codes for immunological data panel slices. HLA allele positions use per-position codes (hla-a-1, hla-a-2, …) so that pattern-discriminator slicing can distinguish allele 1 from allele 2. Non-HLA codes cover DSA, Banff, C4d, ANCA, and related fields.

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system https://hl7.eu/fhir/ig/hl7.eu.fhir.protect-child/CodeSystem/imm-data-component-cs defines the following codes:
