GLUCOSE/GLU
Glucose is measured amperometrically. Oxidation of glucose, catalyzed by the enzyme glucose oxidase,
produces hydrogen peroxide (H
a current which is proportional to the sample glucose concentration.

If results appear inconsistent with the clinical assessment, the patient sample should be retested using
another cartridge.
Intended Use
The test for glucose, as part of the i-STAT
glucose in arterial, venous, or capillary whole blood.
Glucose measurements are used in the diagnosis, monitoring, and treatment of carbohydrate metabolism
disorders including, but not limited to, diabetes mellitus, neonatal hypoglycemia, idiopathic hypoglycemia,
and pancreatic islet cell carcinoma.
Contents
Each i-STAT cartridge contains one reference electrode (when potentiometric sensors are included in the
cartridge configuration), sensors for the measurement of specific analytes, and a buffered aqueous calibrant
solution that contains known concentrations of analytes and preservatives. For cartridges that contain a
sensor for the measurement of glucose, a list of reactive ingredients is indicated below:
Reactive Ingredient
Glucose
Glucose Oxidase
Metrological Traceability
The i-STAT System test for glucose measures glucose amount-of-substance concentration in the plasma
fraction of arterial, venous, or capillary whole blood (dimension mmol L
Glucose values assigned to i-STAT's controls and calibration verification materials are traceable to the
U.S. National Institute of Standards and Technology (NIST) standard reference material SRM965. i-STAT
System controls and calibration verification materials are validated for use only with the i-STAT System and
