N-Lab Pro - Portable Clinical Laboratory Information Management System (LIMS)

N-Lab Pro is a comprehensive, all-in-one Medical Diagnostic Laboratory Management System built for clinical and diagnostic labs of all sizes. It streamlines every aspect of laboratory operations — from patient registration and test booking to result entry, report printing, invoicing, and financial analytics. Developed with a PHP + SQLite backend, N-Lab Pro is designed to run on local servers (XAMPP/WAMP), making it ideal for offline-first environments where internet connectivity may be unreliable. It features a sleek, modern web-based UI accessible from any device on the local network. ✨ Core Features & Modules 1. 🏥 Patient Registration & Management Register patients with UHID (Unique Health ID) auto-generation Capture complete demographics: name, gender, date of birth (DOB) or manual age (Years/Months/Days) Phone, address, and contact details Quick patient search with AJAX-powered live lookup Patient booking history and visit records 2. 🧫 Test Booking & Ordering Book multiple tests in a single visit/bill Category-based test catalog (Hematology, Biochemistry, Microbiology, etc.) Real-time price calculation with support for: Flat discount Percentage-based discount Multiple payment methods: Cash, Card, Online Partial payment & balance/remaining amount tracking Auto-generated unique Bill Numbers (e.g., BILL-0001) 3. 🔬 Result Entry & Test Components Structured test component system with normal ranges and units Supports multi-component tests (e.g., CBC with 15+ parameters) Component heading / sub-heading groups for organized reports Inline result entry with pending / completed status tracking Edit & update results at any time 4. 📄 Report Printing & Online Reports Professional printable lab reports with: Lab logo, name, address, doctor signatures Patient info (UHID, Age, Gender, Ref.
