Resource Profile: Xét nghiệm VN Core — VN Core Observation Laboratory Profile

Official URL: http://fhir.hl7.org.vn/core/StructureDefinition/vn-core-observation-lab Version: 0.1.0
Draft as of 2026-03-20 Computable Name: VNCoreObservationLab

Profile Observation cho kết quả xét nghiệm lâm sàng tại Việt Nam. Sử dụng LOINC làm mã xét nghiệm (66.077 mã unique, bản dịch tiếng Việt do BYT phát hành). BYT đã ban hành bộ mã CLS quốc gia ánh xạ sang LOINC (QĐ 1227/QĐ-BYT 11/04/2025). Căn cứ: QĐ 1227/QĐ-BYT (2025), TT 13/2025/TT-BYT, QĐ 130/QĐ-BYT sửa đổi bởi QĐ 3176/QĐ-BYT (2024).
