- CONTOUR NEXT ONE Blood Glucose Meter
- Lancing Device
- Lancets (quantity may vary)
- CONTOUR NEXT Test Strips (quantity may vary)
- Carrying Case
- User Manual (this document)
Setup
Follow these steps to prepare your CONTOUR NEXT ONE system for use:
- Insert Test Strip: Insert a CONTOUR NEXT test strip into the meter. The meter will automatically turn on.
- Prepare Lancing Device: Remove the cap from the lancing device. Insert a new lancet and twist off its protective cap. Replace the lancing device cap. Adjust the depth setting on the lancing device according to your comfort level (e.g., setting 3 is often a good starting point).
- Perform Control Solution Test (Optional but Recommended): Before first use or if you suspect inaccurate readings, perform a control solution test. Shake the control solution bottle (e.g., Level 2) about 15 times. Apply a drop of control solution to the test strip. Compare the result with the range printed on the test strip vial (e.g., Level 2: 112-140 mg/dL). If the result is within range, the meter is functioning correctly.

Operating Instructions: Blood Glucose Testing
To obtain an accurate blood glucose reading, follow these steps:
- Wash Hands: Wash your hands thoroughly with soap and warm water, then dry them completely.
- Insert Test Strip: Insert a CONTOUR NEXT test strip into the meter. The meter will turn on and display a blood drop symbol.
- Lance Finger: Place the lancing device firmly against the side of your fingertip and press the release button.
- Apply Blood Sample: Gently squeeze your finger until a small drop of blood forms. Touch the tip of the test strip to the blood drop. The meter will draw the blood into the strip.
- Read Result: The meter will display your blood glucose reading within seconds. The SmartLight feature will indicate if your reading is below (red), within (green), or above (yellow) your target range.
- Discard Used Components: Carefully remove the used test strip from the meter and discard it. Remove the lancet from the lancing device and dispose of it safely in a sharps container. Do not reuse lancets or test strips.
