3. Special conditions for use statement(s):

- For prescription use only
- For in vitro diagnostic use only
- The system has not been evaluated for use with neonate venous blood.
- Temperature and humidity extremes - Test results may be inaccurate when test strips are stored outside of the storage and handling conditions.
- Altitudes above 15,000 feet (4500 meters) above sea level have not been evaluated.
- Specimens - Only fresh whole blood or whole blood collected in lithium heparin collection devices should be used for arterial and venous specimens.
- Fluoride, EDTA, Sodium, and Ammonium blood collection devices should not be used.
- Use only whole blood. Do not use serum or plasma.
- Should only be used with single-use, auto-disabling lancing devices
- Caution should be exercised when testing capillary whole blood due to potential pre-analytical variability in capillary specimen collection.
- A capillary whole blood specimen relies upon an adequate, non-compromised capillary blood flow. The healthcare provider must be aware that a capillary whole blood specimen glucose result may not always be the same as an arterial or a venous whole blood glucose result, especially when the patient’s condition is rapidly changing.
- If a capillary whole blood glucose result is not consistent with a patient’s clinical signs and symptoms, glucose testing should be repeated with either an arterial or venous specimen on the StatStrip Xpress Glucose Hospital Meter System.

L. Test Principle:

The StatStrip Xpress Glucose 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.

M. Performance Characteristics (if/when applicable):

This 510(k) is to expand the indications for use for the StatStrip Xpress Glucose Hospital Meter System to include capillary whole blood samples for use in all hospitalized patients based on the clinical studies for the StatStrip Glucose Hospital Meter System established in k181043. The StatStrip Glucose Xpress Hospital Meter uses the exact same technology as the StatStrip Glucose Hospital Meter. Both meters use the Nova StatStrip Glucose Hospital Meter Test Strips to measure glucose, require the same volume of sample, have the same glucose measuring range, and have the same indications for use. The systems differ in minor user preference features that do not impact the usability of the device, such as size of the meter, data storage specifications, and power source. The analytical performance for the
