description: Profile for laboratory panel (order-level) Observations in Bangladesh.\nRepresents an ordered laboratory test panel (e.g. CBC, LFT, RFT) as the\nparent Observation in a hasMember hierarchy.\n\nUsage:\n  - Observation.code is the panel/order code (from BD LOINC Lab Panels ValueSet)\n  - Observation.hasMember references individual result Observations\n    (bd-lab-result-observation) for each component\n  - Observation.value[x] is prohibited — panels do not carry a direct result value\n  - Observation.category is fixed to 'laboratory'\n\nFHIR hasMember pattern:\n  DiagnosticReport.result --> bd-lab-panel-observation\n                                  └── hasMember --> bd-lab-result-observation (x N)
