The Nipro 4SURE Smart Duo Meter is a dual-function device designed to measure both blood glucose and blood ketone levels, enabling patients with diabetes or metabolic conditions to monitor their ketone status accurately. This tutorial video demonstrates the complete ketone testing process: preparing the meter and ketone test strips, collecting a small blood sample, applying it to the strip, and interpreting the digital reading. The system provides quick, reliable results with a clear display, supporting better management of ketosis risk, especially for patients on insulin therapy or following ketogenic diets. Designed for home use and point-of-care monitoring, the Nipro 4SURE Smart Duo combines simplicity, accuracy, and portability for effective self-monitoring.
