Q.STEPS Biometer Dual Monitoring System

The Q.STEPS Biometer G/C Dual Monitoring System is an established handheld diagnostic tool designed to measure whole blood glucose and total cholesterol levels. It was among the first systems to successfully miniaturize enzymatic reduction-oxidation reactions for cholesterol using silver electrodes. The system utilizes separate, specialized strips for each analyte: a circular spot for cholesterol and a half-circle spot for glucose. Each vial of strips is packaged with a lot-specific EEPROM chip that automatically establishes the calibration curve when inserted into the meter, significantly reducing the risk of manual coding errors. While the device does not provide a full lipid profile, its high-speed detection-delivering glucose results in 15 seconds and cholesterol in 30 seconds-makes it a practical choice for proactive health tracking. Clinical evaluations demonstrate that it achieves an accuracy within 10 to 15 percent of laboratory reference methods, providing a reliable baseline for home users and healthcare professionals in non-traditional settings.
