Case Study: Nagalikar Diagnostic

Zero Errors. 100% Automation.

From manual chaos to a fully integrated lab ecosystem. How we bridged diagnostic hardware with cloud software to process 150+ patients daily.

Project Context

Digitizing The Diagnostic Workflow.

Nagalikar Diagnostic is a comprehensive laboratory management and automation platform designed to streamline patient data handling, report generation, and doctor–lab collaboration.

The system was built to eliminate manual data entry errors, improve operational efficiency, and digitize the entire workflow from sample collection to report delivery via WhatsApp.

The Diagnosis

Operational Pain Points

The absence of automation was directly affecting patient throughput and overall business outcomes.

Operational Delays

Manual entry caused significant bottlenecks in report generation during peak hours.

Human Errors

Typographical errors in patient data and test values due to manual feeding.

Inconsistent Formats

Each machine produced reports in different layouts, confusing doctors.

No Data Retrieval

Searching for historical patient records was physically impossible with paper logs.

Communication Gaps

Inefficient coordination between the lab floor and consulting doctors.

Staff Productivity

Technicians spent more time typing than analyzing samples.

System Architecture

Bridging Hardware & Cloud

A custom middleware bridge translates raw serial data from analyzers into structured JSON for the cloud dashboard.

Diagnostic Analyzers

Beckman Coulter, Siemens

RS232 / Serial Protocol

Node.js Bridge

Local Middleware

Parses & Standardizes

Cloud Platform
