# Transfusion Project – FHIR ValueSets + ConceptMap

Author: **Bonnie Shackleford  
Medical Laboratory Scientist • MBA • MSHIM Candidate**

This repository defines structured transfusion-related terminology assets using **FHIR R4**:
- ✅ **Blood Products ValueSet**
- ✅ **Local → SNOMED ConceptMap**
- ✅ Example IG skeleton (`ExampleIG/`)

These artifacts are intended to support interoperability between:
- LIS (Laboratory Information Systems)
- EHR platforms
- Clinical transfusion workflows

Use cases include:
- Order entry decision support
- Normalization of local codes
- Downstream analytics + dashboards
- OR blood planning
