Description**For analysis purposes only - not an active or planned project.** **Ask At Order Entry Questions** for a **distributed WGS (dWGS)** sub-contracted order (IHE LTW `LAB-35`), used alongside the [common core order form](Questionnaire-GenomicTestOrder.html) - see [Order Entry Questions](Questionnaire-GenomicTestOrder.html#order-entry-questions). This Questionnaire carries only the fields from the [dWGS digital manifest](dWGS.html#field-mapping-csv--hl7-v2--fhir) (NHS England `RGL to SGL SOP` Appendix 3, plus 5 local extension fields) that are **not** already asked by the common core - see [dWGS Sub-Order Manifest](Questionnaire-dWGSSubOrder.html) for the full 42-field manifest description, including the fields this Questionnaire deliberately omits because the common core already asks them.

... ReferralReferral / Sub-Order0..1groupDefinition: ServiceRequest
.... dWGS/referral_idOriginal Order Placer Group Number (Referral ID)1..1stringDefinition: ServiceRequest.requisition
..... dWGS/referral_id-designNoteNot the same field as Genomic General Ask At Order Entry's own G Number (Pedigree Number) (Observation.valueString, LOINC 74027-4) - this identifies the referral/requisition shared across every participant's sub-order, the pedigree number identifies a family/pedigree group instead. See dWGS - Outstanding Issues (resolved) for why these were previously confused, and WholeGenomicSequence.html for the pedigree number correction.0..1display
.... dWGS/clinical_indication_test_type_idTest Code0..1choiceDefinition: ServiceRequest.code
Value Set: Genomic Test Codes
..... dWGS/clinical_indication_test_type_id-designNoteThe common core's own Test Code item only appears via enableWhen branches gated on Test Category (Rare and Inherited Disease/Haemoglobinopathy/Cancer) - there is no Whole Genome Sequencing/dWGS Test Category, so none of those branches can fire for a dWGS order. This item fills that gap directly against the broader GenomicTestCodes value set rather than one of the base's narrower per-category lists.0..1display
.... dWGS/ordering_entity_idOriginal Ordering Facility Code0..1stringDefinition: Specimen.identifier.assigner.identifier.value
..... dWGS/ordering_entity_id-designNoteODS code of the original referring Trust - assigner of the Received Sample Identifier (type=PLAC) below, not the same as the Filler Order Ordering Facility Code. Conceptually related to the common core's own Referring Organisation ODS Code / Ordering Facility (HL7/ORC-21), but carried here on Specimen.identifier.assigner rather than PractitionerRole.organization, since dWGS distinguishes the original referring organisation (who provides the specimen) from the requester of this particular sub-order.0..1display
.... dWGS/glh_laboratory_idFiller Order Ordering Facility Code (GLH)1..1stringDefinition: ServiceRequest.requester.identifier.value
..... dWGS/glh_laboratory_id-designNoteA Genomic Laboratory Hub (GLH) ODS code, not the referring Trust's own ODS code - also assigns ServiceRequest.requisition and the Specimen's LIMS identifier (type=FILL). Conceptually related to the common core's own Referring Organisation ODS Code / Ordering Facility (HL7/ORC-21), but identifies the Sequencing Genomic Laboratory acting on this sub-order rather than the clinician's own referring organisation, and is carried directly on ServiceRequest.requester rather than via PractitionerRole.0..1display
.... dWGS/retrospective_sampleRetrospective Sample Flag0..1stringDefinition: ServiceRequest.intent
..... dWGS/retrospective_sample-designNoteValues: "New" (ServiceRequest.intent = filler-order) or "Retrospective" (ServiceRequest.intent = reflex-order - NW Genomics is reflexing further testing off a specimen it already holds, not a fresh sub-order).0..1display
.... dWGS/clinical_informationClinical Information0..1textDefinition: ServiceRequest.note
..... dWGS/clinical_information-designNoteSame FHIR target (ServiceRequest.note) as the common core's own Relevant clinical information and family history item (HL7/NTE-1), but sourced from a different HL7 v2 NTE field occurrence (NTE-3, not NTE-1) - both append to the same note list rather than conflicting.0..1display
.... dWGS/approved_byApproved By0..1string
... PatientPatient0..1groupDefinition: Patient
.... dWGS/patient_ngis_idPatient Identifier (NGIS)1..1stringDefinition: Patient.identifier
..... dWGS/patient_ngis_id-designNoteNo confirmed identifier system - carried as Patient.identifier.assigner (Genomics England, ODS 8J834, who run NGIS), type=PI (v2-0203 Patient internal identifier). The common core's own Patient group (name/DOB/NHS number) is not repeated here - it is asked once by Genomic Test Order itself.0..1display
... AskAtOrderEntryAsk At Order Entry Questions0..1group
.... NOS/FamilyStructureFamily Structure1..1stringDefinition: Observation.valueCodeableConcept
..... NOS/FamilyStructure-designNoteValues: "Singleton", "Duo" or "Trio" - how many people are being tested together as part of this referral. Text-only (no NW-GMSA-confirmed coding system exists), carried as an Observation referenced from ServiceRequest.supportingInfo. See [dWGS - Singleton, Duo and Trio testing](dWGS.html#singleton-duo-and-trio-testing).0..1display
.... NOS/ParticipantTypeParticipant Type1..1stringDefinition: Observation.valueCodeableConcept

.... dWGS/primary_sample_received_dateSample Received Date0..1dateTimeDefinition: Specimen.receivedTime
..... dWGS/primary_sample_received_date-designNoteSame FHIR target (Specimen.receivedTime) as Date and time sample received in lab in NW Genomic General Ask At Order Questions (NOS/SampleReceived) - kept as its own item here since it belongs to dWGS's two-specimen model (primary vs dispatched), not because it is new content.0..1display
.... dWGS/primary_sample_id_as_received_by_glhReceived Sample Identifier0..1stringDefinition: Specimen.identifier
..... dWGS/primary_sample_id_as_received_by_glh-designNoteAssigned by the Original Ordering Facility - coded type=PLAC (Placer Identifier). The same general element as the common core's own Specimen ID Number (LN/80398-1) - this is the PLAC-typed instance of it, specific to the two-specimen (primary/dispatched) dWGS model.0..1display
.... dWGS/primary_sample_id_in_glh_limsLIMS Sample Identifier0..1stringDefinition: Specimen.identifier
..... dWGS/primary_sample_id_in_glh_lims-designNoteAssigned by the Filler Order Ordering Facility (GLH) - coded type=FILL (Filler Identifier). Conceptually the same as the common core's own Lab DNA Number (If Known) (Specimen/accessionIdentifier), which instead uses Specimen.accessionIdentifier rather than a typed Specimen.identifier - the two have not been reconciled onto a single FHIR element.0..1display
.... dWGS/primary_sample_typeSample Type0..1string
..... dWGS/primary_sample_type-designNoteGermline/tumour classifier - low confidence, no clean Specimen field identified; not currently built into any FHIR resource.0..1display
.... dWGS/received_sample_topographySample Topography0..1stringDefinition: Specimen.bodySite
..... dWGS/received_sample_topography-designNoteCancer referrals only. Conceptually overlaps with the common core's own Tissue source/organ of origin (LN/39111-0, Specimen.collection.bodySite) - kept separate pending reconciliation of the exact FHIR path.0..1display
.... dWGS/received_sample_morphologySample Morphology0..1string
.... dWGS/received_sample_tumour_content_pctTumour Content (%)0..1decimal
..... dWGS/received_sample_tumour_content_pct-designNoteCancer referrals only. The same underlying concept as Neoplastic cell content in WGS Local Test Order Ask At Order Entry Questions (NOS/NeoplasticCellContent-wgs) - see dWGS - Comparison with WGS Local Test Order for how the distributed (dWGS) and local paper-based WGS pathways relate.0..1display

..... dWGS/dispatched_sample_volume_ul-designNoteSame FHIR target (Specimen.collection.quantity) as the common core's own Specimen Volume/number of slides or scrolls (LN/3169-0) - kept as its own item because it specifically measures the dispatched DNA volume, not the raw specimen.0..1display
