Making Sense of Blood Tests with FHIRInsight: Turning FHIR into
InterSystems demonstrated how FHIR can be used to structure and clarify blood test data.
Summary
This article introduces 'FHIRInsight,' a tool that utilizes the FHIR standard combined with AI and vector search. The system aims to support decision-making for both healthcare professionals and patients by presenting complex blood test data in an easily understandable format.
Key Players
Details
The article addresses the difficulty of interpreting medical data, specifically blood test results. 'FHIRInsight' is presented as a solution that goes beyond simply explaining values; it provides contextual advice on whether abnormal results are mild, moderate, or severe based on clinical context. It also suggests potential causes, differential diagnoses, and recommends next steps such as follow-up tests or referrals. Technically, the system uses FHIR (Fast Healthcare Interoperability Resources), a global standard for structured health data, as its foundation. It employs a Retrieval-Augmented Generation (RAG) approach by indexing scientific PDF papers and trusted URLs into a vector database. This allows the AI to reference up-to-date academic evidence when making inferences. The process is guided through prompt engineering to identify a wide spectrum of blood-related conditions (e.g., iron deficiency anemia, coagulopathies). Furthermore, a custom adapter was developed using LiteLLM—an abstraction layer—to enable the use of over 100 LLMs (OpenAI, Anthropic, etc.) through a single interface. This allows for the rapid transformation of raw lab values into explainable and actionable medical insights.
