Abstract

Point-of-care (POC) diagnostic systems are designed to deliver rapid, reliable results directly at the site of patient care, whether in clinical settings, ambulatory units, field environments, or even at home. These systems are intended for use by non-specialized personnel and feature short turnaround times. Hilab has developed a miniaturized electrochemical platform that offers an integrated solution for POCT testing. In this study, we present the Hilab Volt system, an electrochemical diagnostic platform comprising dedicated hardware, disposable sensors, and user-friendly software that enables the accurate and efficient detection of key analytes. To validate the system's analytical performance, we report results obtained for a panel of essential electrolytes, K⁺, Na⁺, Ca²⁺, and Cl⁻, demonstrating its potential for clinical application in decentralized testing environments. The recovery ranges (n = 67) were 84-112%, 94-101%, 80-125%, and 97-104% for K⁺, Na⁺, Ca²⁺, and Cl⁻, respectively. For all sensors, satisfactory results were obtained (r > 0.8 and p > 0.8) using control samples. The Hilab Volt system demonstrated reliable analytical performance for key electrolytes, with recovery values and correlation metrics supporting its suitability for point-of-care use. Its miniaturized design, ease of operation, and accurate detection capabilities make it a promising solution for decentralized clinical testing, enabling rapid and accessible diagnostics across diverse care settings.
