5.1. Performing a Blood Glucose Test

Follow these 6 simple steps for an accurate blood glucose reading:

1. Clean and dry your hands thoroughly.
2. Install a new lancet into the lancing device (refer to Section 4.2).
3. Insert a fresh test strip into the monitor. The monitor will automatically turn on.
4. Use the lancing device to collect a blood sample from your fingertip.

5.3. Automatic Siphoning Technology

The monitor utilizes drip-free technology. Simply touch the target area of the test strip to a tiny blood drop (0.7 µL, approximately half a rice-sized drop). It fills instantly with the precise amount needed for highly accurate results.

6. Maintenance

6.1. Cleaning the Monitor

To clean the monitor, wipe the exterior with a soft, damp cloth. Do not immerse the monitor in water or use harsh cleaning agents. Ensure no liquid enters the test strip port.

6.2. Storage

7. Troubleshooting

7.1. Why do results vary between brands?

Each brand of blood glucose monitor uses unique algorithms and strip technologies. All ISO 15197 certified devices meet clinical accuracy (±15%). Differences within this range are considered normal.

7.2. Why do home and hospital results differ?

A standard range of ±15% difference is normal per ISO standards. Home tests typically use finger capillary whole blood, while hospital tests often use venous plasma. These different sample types can lead to variations in results.

7.3. What is control solution for?

Control solution checks if your meter and test strips are working properly by simulating a blood test. It contains a known amount of glucose that reacts with the test strips. Compare the result with the range printed on the test strip vial. If the result is out of range, the strips or meter may be faulty, or the control solution may be expired.
