The Glucose Hexokinase II in vitro diagnostic procedure is intended to measure glucose in human serum, plasma and urine on the Bayer ADVIA® 1650 System. Such measurement is used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, idiopathic hypoglycemia and insulin overdose.
The Glucose Hexokinase II in vitro diagnostic procedure is intended to measure glucose in human serum, plasma and urine on the Bayer ADVIA® 1650 System. The assay buffer is in dual aliquots, allowing for blanking and subtraction of potential interference effects.
Acceptance Criteria and Device Performance for Glucose Hexokinase II method for Bayer ADVIA® 1650 System (K011963)
This submission (K011963) is a 510(k) for a new version of a Glucose Hexokinase assay, called Glucose Hexokinase II, for the Bayer ADVIA® 1650 System. The submission claims substantial equivalence to the predicate device, also a Glucose Hexokinase assay (K991576). The "acceptance criteria" can be inferred from the reported performance of the predicate device, with the new device demonstrating comparable or improved performance.
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are not explicitly stated as numerical thresholds in this 510(k) summary. Instead, the sponsor demonstrates that the new device's performance characteristics (Imprecision, Correlation, Interfering Substances, Analytical Range) are comparable to, or improved relative to, those of the predicate device.
