Quick Start

# 1. Clone the repository
git clone https://github.com/yourusername/hemoscan-ai.git
cd hemoscan-ai

# 2. Install dependencies
npm install

# 3. Set up environment variables
# Create .env.local file with:
VITE_SUPABASE_URL=your_supabase_url
VITE_SUPABASE_ANON_KEY=your_supabase_anon_key

# 4. Set up database
# Go to Supabase SQL Editor and run: database/schema.sql

# 5. Start development server
npm run dev

# 6. Open browser at http://localhost:3000

Database Setup

-- Run in Supabase SQL Editor
-- File: database/schema.sql

-- Creates 4 tables:
-- 1. profiles (user accounts)
-- 2. patient_reports (blood test results)
-- 3. recovery_paths (personalized recommendations)
-- 4. test_bookings (lab appointments)

-- Includes Row-Level Security policies
-- Automatic triggers and constraints

🔬 How It Works

1. Blood Report Upload

User uploads image → FileReader → Base64 encoding →
Gemini AI OCR → Extract: Hb, MCV, MCH, MCHC, demographics →
Validate data → Auto-fill form

2. ML Prediction

Input values → Normalize with saved mean/std →
Ridge Classifier → Sigmoid output (0-1) →
Threshold at 0.5 → Binary prediction + confidence score

3. AI Analysis (if quota available)

Patient data + ML prediction → Gemini 2.5 Flash →
Medical reasoning → Anemia classification →
Risk level + Clinical summary → Combine with ML for hybrid result

4. Save & Track

Hybrid result → Supabase PostgreSQL →
Generate recovery path → Update user dashboard →
Show detailed analysis + charts
