It is not intended for use with neonate cord blood specimens. It is not intended for the screening or diagnosis of diabetes mellitus but is indicated for use in determining dysglycemia.

Device Story

Point-of-care glucose monitoring system; uses electrochemical biosensor technology with glucose oxidase enzyme. Input: capillary, venous, or arterial whole blood (1.2 μL) applied to test strip via capillary action. Meter measures current proportional to glucose concentration; displays result in 6 seconds. Used in hospital/professional settings by healthcare staff. Modified version adds Wi-Fi connectivity for data transmission to facility networks and updated docking/charging stations. Data stored on-device (1000 patient tests, 200 QC, 4000 operators). Output used by clinicians for rapid glucose assessment and dysglycemia management. Benefits include immediate bedside results, reducing turnaround time compared to central lab testing. Device supports multiple-patient use with validated disinfection protocols.

L. Test Principle:
The Nova StatStrip Hospital Meter System is based on electrochemical biosensor technology and the principle of capillary action. The system quantitatively measures blood glucose levels using glucose oxidase enzyme chemistry. The electrons generated during this reaction are transferred from the blood to the electrodes. The magnitude of the resultant current is proportional to the concentration of glucose in the specimen and the signal is converted into a readout displayed on the meter.
