The Certeza GL-100 is a fully featured blood glucose monitor offering comprehensive monitoring capabilities at an economical price point. Using glucose dehydrogenase (GDH) enzyme technology with code-free operation, it requires just 0.6 µL of capillary whole blood and delivers results in 5 seconds — making it one of the faster options in the Certeza glucometer range.
A 360-test memory with 7, 14, and 28-day averaging provides extensive long-term trend monitoring. Alarm alerts for testing schedule reminders help users maintain consistent measurement routines. The meter also displays the patient’s hematocrit value (0–70%), providing additional clinical context. A built-in strip ejector enables hygienic, touchless disposal of used strips. GL-100 test strips have a 24-month shelf life — among the longest available. The meter conforms to ISO 15197:2013. Power is supplied by a single CR2032 battery.

Usage Instructions
- Insert a Certeza GL-100 test strip into the meter — it powers on and auto-codes.
- 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 blood glucose reading. The strip ejector allows hygienic disposal.
- Review averages (7/14/28-day) and refer to the user manual for full guidance.
Warnings and Precautions
- For in vitro diagnostic use only — external blood glucose testing only.
- Use only Certeza GL-100 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-100 differ from the GL-110?
The GL-100 and GL-110 are both Certeza glucometers with GDH enzyme, code-free operation, 0.6 µL sample, and 5-second results. The GL-100 has a larger 360-test memory (vs 200 for GL-110), three averaging periods (7/14/28-day vs none specified for GL-110), adds alarm alerts, hematocrit display, and strip ejector, and uses economical larger test strips with a 24-month shelf life. The GL-110 features individually foil-wrapped strips and colour-coded high/low alerts. Choose GL-100 for more memory and features; GL-110 for colour-coded alerts and foil-wrapped strips.
What does the hematocrit display show?
Haematocrit (HCT) is the proportion of red blood cells in the blood. Many blood glucose meters are affected by haematocrit levels outside the normal range — affecting reading accuracy. The GL-100 displays the patient’s HCT value (0–70%) alongside the glucose reading, providing additional clinical context for interpreting results in patients with anaemia or polycythaemia.
How long are the GL-100 test strips valid?
Certeza GL-100 test strips have a 24-month unopened shelf life — one of the longest available among standard glucometer strips.
