Indications for Use

The StatStrip Xpress 2 Glucose Hospital Meter System is intended for point-of-care, in vitro diagnostic, multiple-patient use for the quantitative determination of glucose in capillary finger stick, venous whole blood, arterial whole blood, neonate arterial whole blood, and neonate heel stick specimens throughout all hospital and all professional healthcare settings, including patients receiving intensive medical intervention/therapy. The system should only be used with single-use, auto-disabling lancing devices when performing a capillary finger stick or neonate heel stick. 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

Handheld point-of-care glucose meter; uses electrochemical biosensor technology with glucose oxidase enzyme chemistry. Input: fresh whole blood (capillary, venous, arterial, neonate heel/arterial) applied via capillary action to test strip. Meter measures electrons generated by glucose oxidation; magnitude of current proportional to glucose concentration. Output: quantitative glucose result on dot-matrix display. Used by healthcare professionals in hospital settings. Device features 2 AAA battery power, 3-button interface, and internal storage for patient/QC tests. Benefits: rapid bedside glucose monitoring for dysglycemia management in diverse patient populations, including intensive care. Requires single-use, auto-disabling lancing devices for capillary/heel stick samples.

Clinical Evidence

No new clinical studies performed. Substantial equivalence relies on analytical and clinical performance data previously established in k060345, k063821, k132121, and k181043. Performance for capillary fingerstick samples in hospitalized patients, including those receiving intensive medical intervention, was established in k181043. Bench testing confirmed device robustness, disinfection efficacy, and hematocrit/altitude/temperature/humidity specifications.

Technological Characteristics

Electrochemical biosensor; glucose oxidase enzyme. Measuring range: 10-600 mg/dL. Sample volume: 1.2 μL. Hematocrit range: 20-65%. Power: 2 AAA batteries. Display: dot matrix with 3 push buttons. Connectivity: none (standalone). Disinfection: validated for Clorox Germicidal Wipes (EPA #67619-12).

Indications for Use

Indicated for quantitative glucose determination in capillary finger stick, venous, arterial, neonate arterial, and neonate heel stick whole blood specimens in all hospital/professional healthcare settings, including patients receiving intensive medical intervention. Not for neonate cord blood, screening, or diagnosis of diabetes mellitus.

Regulatory Classification

- 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.

L. Test Principle:

The StatStrip Xpress 2 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 2 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 Xpress 2 Glucose 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 StatStrip Xpress 2 Glucose Hospital Meter System has been previously established in
