The Certeza GL-107 is a reliable and economical blood glucose monitor designed for accurate self-monitoring of blood glucose levels at home and in professional settings. Using glucose oxidase enzyme technology with an auto-coding chip system, it requires just 0.6 µL of blood and delivers results in 5 seconds across a measurement range of 40 to 600 mg/dL.
The auto-coding chip is inserted when starting a new box of test strips, calibrating the meter to that batch’s specific chemistry without manual code entry. A 360-test memory with 7, 14, and 28-day averaging supports comprehensive long-term glucose trend monitoring. Large test strips provide easier handling for elderly users and those with limited dexterity. The complete kit includes a custom-designed lancing device, 3V lithium battery, and carrying case.
Why Choose Certeza Blood Glucose Monitor
- Glucose Oxidase Enzyme: Established enzymatic measurement method widely used in clinical-grade blood glucose systems.
- Auto-Coding Chip: Insert the chip when opening a new box of strips — no manual code number entry required. The chip calibrates the meter to the batch.
- 0.6 µL Sample Size: Small blood volume minimises discomfort during daily finger-prick testing.
- 5-Second Results: Fast reading time for minimal waiting.
- Measurement Range 40–600 mg/dL: Covers the full clinically relevant adult range.
- 360-Test Memory: Stores 360 readings for comprehensive long-term trend tracking.
- 7, 14, and 28-Day Averaging: Three averaging periods for flexible short- and long-term glucose trend monitoring.
- Large Test Strips: Easier to handle — beneficial for elderly users and those with limited dexterity.
- Economical: Cost-effective per-test pricing for regular daily monitoring.
- Carrying Case Included: Organised, portable storage for the complete kit.
- Medical-Grade: Suitable for both self-testing and professional clinical use.

Usage Instructions
- Insert the auto-coding chip when opening a new box of test strips — this calibrates the meter to that batch.
- Insert a GL-107 test strip into the meter — it powers on and reads the chip automatically.
- Wash and dry hands. Use the lancing device to obtain a 0.6 µL blood sample from the fingertip.
- Apply the blood drop to the test strip. The strip draws in the sample automatically.
- Wait 5 seconds for the reading to appear on the display.
- Record your result if needed and dispose of the used strip and lancet safely.
Warnings and Precautions
- For in vitro diagnostic use only — external blood glucose testing only.
- Use only Certeza GL-107 test strips. Other strips will give inaccurate results.
- Always insert the correct auto-coding chip when starting a new box of test strips.
- Do not use expired test strips.
- Dispose of used lancets in a puncture-resistant sharps container.
- Always consult a healthcare professional to interpret readings and manage blood glucose.

Frequently Asked Questions
How does the GL-107 differ from the GL-100?
Both have 0.6 µL sample size, 5-second results, 360 memory, and 7/14/28-day averaging. The key differences: GL-107 uses glucose oxidase enzyme (vs GDH in GL-100), an auto-coding chip (vs fully code-free in GL-100), and has a narrower measurement range (40–600 mg/dL vs 9–600 mg/dL). The GL-100 adds strip ejector, hematocrit display, and alarm alerts. The GL-107 includes a carrying case and is the more economical option.
What is an auto-coding chip?
An auto-coding chip is a small chip included in each new box of test strips. Insert it into the meter to calibrate it to that specific batch’s chemistry. Unlike fully code-free meters (which calibrate automatically without any chip), the GL-107 requires chip insertion per new box — but no manual number entry is needed.
How many readings does the GL-107 store?
360 test results, with automatic calculation of 7, 14, and 28-day averages for trend monitoring.
