AI-Powered Blood Test Report Interpretation System

Medical Report Analyzer is an AI-driven application designed to automate the extraction, interpretation, and summarization of blood test reports. The system leverages OCR, Large Language Models (LLMs), and an agent-based architecture to convert complex medical data into clear, patient-friendly insights.

Built with scalability and responsible AI principles in mind, this project demonstrates how multi-agent AI systems can be applied to real-world healthcare use cases.

Blood test reports are often difficult for non-medical users to understand due to complex terminology and numerical reference ranges. Manual interpretation is time-consuming and requires medical expertise.

This project aims to:

• Automate blood report analysis.
• Improve healthcare data accessibility.
• Provide simplified, explainable insights for patients and students.

• 📄 Automated OCR Extraction from uploaded blood test reports.
• 🤖 Agent-Based Architecture using CrewAI.
• 🧠 LLM-Powered Medical Interpretation with reference range mapping.
• 📝 Patient-Friendly Summaries generated via prompt engineering.
• 🎛 Streamlit Web Interface for easy report upload and analysis.
• 🔄 Modular & Scalable Design for future diagnostic extensions.
• 🔐 Responsible AI Practices with no sensitive data retention.

The system is built using a multi-agent pipeline, where each agent performs a specialized task:

1. OCR Parser Agent

   • Extracts text from uploaded blood reports using Tesseract OCR.

2. Health Data Interpreter Agent

   • Identifies medical parameters.
   • Maps values to standard reference ranges.
   • Generates contextual medical insights using LLMs.

3. Summary Generator Agent

   • Converts technical results into simplified, patient-friendly explanations.

Agents are orchestrated sequentially using CrewAI to ensure clean data flow and modular execution.

• Hugging Face Transformers
• Prompt Engineering & Caching

• Tesseract OCR

• Python
• Modular agent workflows
• Structured data passing between agents

• Streamlit (Interactive web UI)

git clone https://github.com/ahmasmibhanu/HealthLens.git
cd HealthLens

pip install -r requirements.txt

streamlit run app.py

1. Upload a blood test report (PDF or image).
2. OCR extracts the report text.
3. AI agents analyze medical parameters.
4. A simplified, patient-friendly summary is generated.
5. Results are displayed in real-time on the UI.

• Reduced manual effort in interpreting blood reports.
• Improved healthcare data accessibility for non-technical users.
• Achieved accurate extraction across diverse report formats.
• Received positive usability feedback from medical students and early testers.
• Demonstrated the feasibility of agent-based AI systems in healthcare.

• Backend API using FastAPI.
• Database integration for report history.
• Explainability scores and confidence metrics.
• Authentication and role-based access.
• Support for additional diagnostics (X-ray, MRI reports).
• Deployment using Docker and cloud platforms.
