System Workflow

How SeHAT Works in 3 Simple Steps

Designed so any user — from a tech-savvy student to an elderly parent — gets instant health clarity.

01

Snap a Photo or Speak Your Query

Take a clear photo of any blood test report or hold the mic button to describe your symptoms in Hindi, English, or conversational Hinglish.

02

AI Analyzes & Contextualizes

The OCR pipeline parses numerical values against standard biological intervals while FAISS semantic retrieval grounds the answer in clinical guidelines.

03

Plain-Language Advice & Action

Receive clear, understandable explanations of what the results mean, follow-up questions to ask your doctor, or set automatic medication alerts.

The Engineering Story

From Real-World Friction to Production System

Why this system had to be built, the technical hurdles encountered, and how InfoHQ solved them.

The Healthcare Clarity Gap

Why We Built SeHAT: Medical Reports Shouldn’t Need a Degree to Read

When families receive blood test results or pathology reports, they are confronted with dense clinical jargon, technical units, and cryptic abbreviations. Without immediate clinical context, patients experience high anxiety or turn to unverified internet forums.

Cryptic Pathology Jargon

Phrases like "Microcytic Hypochromic Anemia" or "Platelet Count 110,000 /mcL" cause immediate panic when non-clinical users cannot contextualize normal reference ranges.

The Language Barrier in India

Over 80% of Indian families think and communicate in Hindi or regional languages. Most medical apps provide English-only interfaces with zero colloquial voice support.

Fragmented Healthcare Apps

Users are forced to juggle 4 separate apps: one for lab booking, one for pill alarms, another for first-aid, and standard phone calls during critical emergencies.

The Engineered Solution

A Unified, Trilingual Mobile Companion Powered by Context-Grounded AI

We engineered SeHAT as an all-in-one mobile platform combining a native Android client with high-speed Python microservices. By combining FAISS vector search with OCR and Speech Recognition, users can either photograph their reports or speak their symptoms naturally.

Instant Lab Report OCR

CameraX and PDF parsers isolate test names, values, and biological reference intervals, generating jargon-free summaries in plain English, Hindi, or Hinglish.

RAG-Grounded Medical Chatbot

FAISS vector search queries verified clinical medical guidelines, ensuring AI answers are strictly grounded and cited with standard medical disclaimers.

One-Tap Emergency GPS Broadcast

High-priority FusedLocation fixes package Google Maps coordinates and broadcast live emergency alerts to trusted family contacts via SMS and WhatsApp.

Differential Clinical Assessment & Vision OCR Document Parsing

AI Symptom Checker & Medical Report Analyzer

Ranked differential symptom analysis with clinical matching (High, Moderate, Low Match), paired with a document OCR pipeline processing camera photos and PDFs of blood tests (CBC, Glucose, Platelets, Creatinine) into plain-language summaries.

⚙Under The Hood • Engineering Architecture:
  • •Differential engine evaluates multi-symptom inputs against an indexed clinical association graph to produce probabilistic tiers: High, Moderate, and Low Match.
  • •CameraX captures test documents or user uploads PDFs, passing image buffers to an OCR extraction pipeline that isolates clinical test tokens and numerical values.
  • •Parsers normalize extracted values against standard biological reference intervals (e.g. Platelets: 150,000–450,000 /mcL), generating plain-language explanations of abnormal ranges.
