## Resource Profile: Bangladesh Laboratory Result Observation

Official URL: https://fhir.dghs.gov.bd/core/StructureDefinition/bd-lab-result-observation | Version: 0.4.4
Standards status: Informative | Maturity Level: 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 and Bangladesh Laboratory Report

You can also check for usages in the FHIR IG Statistics
