Laboratory: probe tracking by barcodes and results portal

We manage a medical diagnostic laboratory, and we need a unified web system that handles a test order from registration to the moment a patient reads the final report. Currently, requests are on paper, samples are matched to people manually, and results are entered twice — we waste time and occasionally mix up samples. We need a clean process: a doctor or receptionist creates an order, selects needed test panels, and the system prints labels on test tubes with unique barcodes that accompany the sample at every stage. The core of the project is probe tracking and results entry. Each barcode must be scanned when received, by the analyzer, and at the verification stage, so we always know where the sample is and who has worked with it. The technician enters measured values for assigned tests, and the system must compare each value with the reference range for the patient's sex and age and flag anything low, high, or critical. The result cannot be released until confirmed by a second qualified specialist; we need complete history — who entered, corrected, and signed each figure. The final part is a secure portal: patients see completed reports with understandable flags and simple explanations, download PDF, and track orders in progress, while doctors get an overview of their referred patients with trend graphs. Implement role-based access, encrypted storage, and structured export so we can later connect analyzers and external clinical systems. Expected scope: — order creation with customizable test panels; — barcode label printing and scanning at each station; — results entry with reference ranges and auto-flags; — two-stage validation and complete audit log.
