FHIR profiles

FHIR profiles are specialized definitions within the FHIR healthcare data standard that tailor general data structures to specific needs, such as representing a particular medical test or patient information for a specific setting. They ensure consistency and accuracy by setting rules about what data can be included and how it should be formatted, making it easier for different healthcare systems to share and understand patient information reliably. Basically, profiles customize the standard to fit particular use cases while maintaining interoperability across health IT systems.
