Details
This document details the methodology for representing 'Laboratory Results' based on the FHIR standard. Specifically, it recommends the use of the `DiagnosticReport` resource conforming to US Core Profile 6.1.0. This report type can store comprehensive information provided by a diagnostic service, such as measured items (LOINC codes), patient data, result status, and reporting dates. Technically, it supports not only simple data fields but also the 'presentedForm' element for free text or images. Furthermore, detailed specifications are provided for search functionality, allowing advanced queries combining patient ID, category (LAB), code, and date ranges (gt, lt, ge, le). These standardized API endpoints and data structures provide crucial guidelines for standardizing the handling of lab results in Japanese electronic medical records and healthcare information systems. This ensures seamless interoperability between different vendor systems, allowing physicians to grasp a patient's status quickly and accurately.
