Introduction The Nova StatStrip Xpress Glucose Hospital Meter is a hand-held, battery-powered, in vitro diagnostic laboratory instrument that works in conjunction with Nova Biomedical glucose electrochemical test strips to measure glucose in a whole blood sample, a Quality Control (QC) solution, linearity, or proficiency solutions.
Introduction Clinical Utility The Nova StatStrip Xpress Glucose Hospital Meter System is intended for in vitro diagnostic use by health care professionals and for Point-Of-Care usage for the quantitative measurement of glucose in capillary, venous, arterial, and neonate whole blood. It is indicated for use in a clinical setting by health care professionals as an aid to monitor the effectiveness of diabetes control.
Introduction Interfering Substances Glucose Interferences: The Nova StatStrip Xpress Glucose Hospital Meter exhibits no interference from the following substances up to the following concentration levels: Substances Conc Substances Conc mg/dL(mmol/L) mg/dL(mmol/L) D(+) Maltose 240.0 (6.66) Acetaminophen 10.0 (0.66) D(+) Maltotetraose 240.0 (3.6) Ascorbic Acid 10.0...
Introduction Operation Overview • To perform a test, the operator inserts a test strip into the test strip port. Touch the end of the strip to a drop of blood, QC solution, or linearity solution. The results are obtained in 6 seconds. •...
Introduction • A coin-size battery provides power to operate the meter. The battery provides sufficient power to operate for approximately 600 tests. A low-battery warning on the meter display alerts the operator to change the battery. An auto sleep feature conserves power when the meter is not in use.
Page 22
Introduction If the meter goes into sleep mode, the following conditions should be expected: • If blanking occurs when a Patient Result screen is displaying, the result is automatically saved. • If the currently displayed screen is a Setup screen, any unconfirmed input data or menu selection are discarded prior to blanking.
Setup This section describes how to setup the Nova StatStrip Xpress Glucose Hospital Meter. The operator can set the meter for local time and date, have the beeper On or Off, enable the sample counter, and set the date display format. Installing the Battery (Replacing) The meter is powered by a single 3V coin cell battery, 2450.

External controls materials are available from Nova Biomedical for verifying the integrity of the Nova StatStrip Xpress Glucose Hospital Meter. These StatStrip Glucose Control Solutions consist of 3 levels of ready-to-use liquid controls. They are formulated at clinically relevant levels.
Only the Nova StatStrip Glucose Control Solutions are rec- ommended for use with the Nova StatStrip Xpress Glucose Meter and the Nova StatStrip Glucose Test Strips. Ranges for the Nova StatStrip Xpress Glucose Meter using other commercially available glucose controls have not been established and may give erroneous results.

Testing a Quality Control Solution Good Laboratory Practice principles suggest that external controls must be run whenever the laboratory director has any question about the test system integrity or operator technique. This section describes how to run QC (Quality Control), Linearity Solution, Proficiency Solution, and blood samples.
Page 38
Testing a Quality Control Solution 2. Identify the sample as a Control; use the Left or Right button to find the desired control level: C1, C2, or C3. 3. Touch the end of the test strip to a drop of control solution until the test strip fills and the meter beeps.
Page 39
Testing a Quality Control Solution 4. Glucose quality control test results are available on- screen in 6 seconds. Result Result Displayed Displayed in in mg/dL mmol/L 5. There is one long beep when the results are ready. There are 3 short beeps if test results are outside the measurement range of the test strip.
Testing a Blood Sample NOTE: Do not test patient samples until control solution test results are within expected range. 1. Insert a test strip into the meter. Verify that all segments of the screen display. If the display is incomplete, discontinue use for diagnostic testing. Then a flashing blood drop will display.
Page 41
Testing a Blood Sample 2. Wash patient's hand with water then dry thoroughly. Alternatively, use alcohol pads to clean area; dry thoroughly after cleaning. 3. Holding hand down- ward, massage finger with thumb toward tip to stimulate blood flow. 4. Use a lancet to puncture the finger.
Page 42
Testing a Blood Sample 5. Squeeze the finger to form a drop of blood. 6. When the blood drop appears, touch the end of the test strip to the blood drop until the test strip fills and the meter beeps. 7.
Page 43
Testing a Blood Sample Result in mg/dL Result in mmol/L 8. There is one long beep when the results are ready. There are 3 short beeps if test results are outside the range of the test strip.
Page 44
Testing a Blood Sample If result is LO (less than the measurement range) or Hi (greater than the measurement range) repeat the test. HI in mg/dL LO in mmol/L NOTE: Test results are automatically saved. If no activity for 1 minute, the meter will time-out: screen goes blank.
Testing a Linearity/Proficiency Solution For CLIA Moderate Settings only: This section describes how to perform Linearity tests with the StatStrip Xpress Glucose Hospital Meter. There are 5 levels in the StatStrip Glucose Linearity kit. Refer to the StatStrip Linearity Kit package insert sheet for complete instructions, indications, precau- tions, and limitations of the system.
