Laboratory tests that can be requested ("requestables") and test groups: the members of the SNOMED CT UK Edition refset 1853561000000109 Pathology and laboratory medicine procedure simple reference set (PaLM), UK Edition release 20250702 (358 concepts). This is the England equivalent, for pathology, of the National Genomic Test Directory (genomics) and NICIP (imaging): laboratories map their local test codes to it. Results are coded from the PaLM observables refset 1853551000000106 instead.

The codes are listed (rather than given as a refset rule, as UK Core's UKCore-PathologyAndLaboratoryMedicineProcedures does) because the UK Edition on tx.fhir.org is older than this refset. Generated by scripts/palm_valueset.py from CSIRO's public Ontoserver; re-run it for a new UK Edition release.

• Include these codes as defined in http://snomed.info/sct version Not Stated (use latest from terminology server)
