Cera-Chek 1Code Prime (G300/G400)

The Cera-Chek 1Code Prime (G300/G400) is a specialized 3-in-1 electrochemical monitoring system designed to measure total cholesterol, glucose, and uric acid. A primary engineering advantage of this system is its exceptionally wide hematocrit range of 10-70%, which allows for accurate testing in neonatal and gestational populations where red blood cell counts are typically elevated. The device utilizes FAD-dependent glucose dehydrogenase (GDH-FAD) enzyme strips, which minimize clinical interference from oxygen and non-glucose sugars like maltose-a critical feature for patients receiving certain specialized therapies. While the system provides rapid results in 26 seconds for cholesterol, its clinical accuracy is benchmarked at approximately ±15%, making it more suitable for proactive trend tracking rather than definitive clinical management. Technical features such as 'insufficient blood detection' alerts and a USB interface for data management further enhance its utility for long-term metabolic health tracking.
