## Resource Profile: Bangladesh Observation Profile 

| | | |
| :--- | :--- | :--- |
| *Official URL*:https://fhir.dghs.gov.bd/core/StructureDefinition/bd-observation | *Version*:0.4.2 | |
| * Standards status: *[Informative](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 1 | *Computable Name*:BDObservationProfile |

 
Base observation profile for Bangladesh. This is an abstract-style base profile from which all BD-Core observation profiles are derived. It is not intended to be used directly in clinical resources — use a derived profile instead. 
Derived profiles (v0.4.0): 
* bd-lab-panel-observation : Laboratory panel/order (hasMember pattern)
* bd-lab-result-observation : Laboratory leaf result (child of hasMember)
 
Planned derived profiles (v0.5.0+): 
* bd-vital-signs-observation
* bd-exam-observation
 

**Usages:**

* Derived from this Profile: [Bangladesh Laboratory Panel Observation](StructureDefinition-bd-lab-panel-observation.md) and [Bangladesh Laboratory Result Observation](StructureDefinition-bd-lab-result-observation.md)
