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