## Resource Profile: Bangladesh Laboratory Result Observation 

| | | |
| :--- | :--- | :--- |
| *Official URL*:https://fhir.dghs.gov.bd/core/StructureDefinition/bd-lab-result-observation | *Version*:0.4.5 | |
| * Standards status: *[Informative](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 1 | *Computable Name*:BDLabResultObservationProfile |

 
Profile for individual laboratory result (component-level) Observations in Bangladesh. Represents a single test result within a laboratory panel (e.g. Haemoglobin within a CBC panel). 
Usage: 
* Observation.code is the result/component code (from BD LOINC Lab Results ValueSet)
* Observation.value[x] is required — every leaf result must carry a value
* Observation.hasMember is prohibited — leaf results cannot group further
* Observation.derivedFrom references the parent panel Observation
* Observation.category is fixed to 'laboratory'
 
FHIR hasMember pattern: bd-lab-panel-observation └── hasMember –> bd-lab-result-observation (this profile) 
Coded results (Ord/Nom scale): Use valueCodeableConcept with codes from BD LOINC Answer Lists ValueSet. 

**Usages:**

* Refer to this Profile: [Bangladesh Laboratory Panel Observation](StructureDefinition-bd-lab-panel-observation.md) and [Bangladesh Laboratory Report](StructureDefinition-bd-lab-report.md)
