The UniCel DxC 800 System Software Version 5.0 is a fully automated, computercontrolled clinical chemistry analyzers intended for the in vitro determination of a variety of cleared clinical laboratory assays, such as glucose. GLUCm reagent is intended for the quantitative determination of glucose concentration in human serum, plasma, urine or cerebrospinal fluid (CSF). Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, idiopathic hypoglycemia, and pancreatic islet cell carcinoma.

Device Story

UniCel DxC 800 SYNCHRON System is a fully automated, computer-controlled clinical chemistry analyzer for in vitro diagnostic testing. It processes human serum, plasma, urine, or CSF samples. The system utilizes an oxygen rate electrode method where samples are injected into a reaction cup containing glucose oxidase; the peak rate of oxygen consumption is measured, which is directly proportional to glucose concentration. The system features bar code identification, closed tube sampling, and obstruction detection. It is operated by laboratory personnel in a clinical setting. Software version 5.0 introduces USB data storage, network printer support, patient name-based result retrieval, and modified stirrer bar operation during reagent fill. Output is provided as quantitative glucose concentration values, which clinicians use to diagnose and manage carbohydrate metabolism disorders.

L. Test Principle:
Glucose concentration is measured by an oxygen rate method employing a Beckman Coulter Oxygen electrode. A sample is injected in a reaction cup containing a glucose oxidase solution. The ratio used is one part sample to 76 parts reagent. The peak rate of oxygen consumption is directly proportional to the concentration of glucose in the sample. Oxygen is consumed at the same rate as glucose reacts to form gluconic acid.
