DEVELOPMENT OF A PROGRAM FOR ANALYZING MEDICAL LABORATORY RESULTS USING ARTIFICIAL INTELLIGENCE MODELS
DOI:
https://doi.org/10.5281/zenodo.19606581Abstract
This paper presents the concept and architecture of an intelligent system for automatic processing of medical
laboratory test results. The system integrates three key components: EasyOCR-based optical character recognition
for extracting data from scanned forms, structured JSON storage for normalized results, and a local language model
(OLM) via the Ollama framework for generating personalized medical recommendations. The application of Retrieval-
Augmented Generation improves the clinical accuracy of recommendations to 4.6 out of 5.0 points. The achieved OCR
accuracy of 95.5% for numerical fields meets ISO 15189 requirements. Total processing time per form does not exceed
17 seconds on CPU. The key advantage is a fully local architecture ensuring compliance with GDPR, HIPAA, and Federal
Law No. 152-FZ on personal data.
