These blood glucose test strips are designed for use with the On Call® PLUS and On Call® EZ II blood glucose meters, manufactured by ACON Laboratories. Using glucose oxidase enzyme technology, each strip reacts with a small capillary whole blood sample to produce an accurate, plasma-equivalent glucose reading within approximately 10 seconds.
Each strip requires only 1 µL of blood — a small enough sample to be obtained comfortably from the fingertip, palm, or forearm. The strips use Code 690 calibration and are supplied in individually protected packaging to maintain accuracy and prevent contamination. This pack contains 50 test strips, providing approximately one to two months of supply for daily monitoring.
Why Choose On Call Test Strips
- Compatible Meters: Designed exclusively for use with On Call® PLUS and On Call® EZ II blood glucose meters.
- Glucose Oxidase Technology: Each strip uses glucose oxidase enzyme-based amperometric testing for accurate, reliable readings.
- Small Sample Size: Requires only 1 µL of blood — reducing discomfort during fingerstick sampling.
- Fast Results: Delivers plasma-equivalent blood glucose readings in approximately 10 seconds.
- Wide Measuring Range: 20 to 600 mg/dL — suitable for monitoring across the full spectrum of glucose levels.
- Alternative Site Testing: Supports sample collection from fingertip, palm, and forearm.
- Code 690 Calibration: Pre-coded strips ensure accurate calibration without manual entry.
- Plasma-Equivalent Results: Results are calibrated to plasma values for consistency with laboratory reference standards.
- Pack of 50: Suitable for approximately one to two months of daily testing.

Usage Instructions
- Wash and dry hands thoroughly before testing.
- Open the vial and remove one test strip. Reseal the vial immediately.
- Insert the test strip into the On Call PLUS or EZ II meter strip port.
- Use a lancing device to obtain a small blood sample (1 µL) from the fingertip, palm, or forearm.
- Touch the sample tip of the test strip to the blood drop. The meter will confirm sufficient sample with a beep.
- Wait approximately 10 seconds for the result to display on the meter screen.
- Record the result if needed. Safely dispose of the used strip.
- Refer to the On Call PLUS or EZ II user manual for complete testing guidance.
Storage Instructions
- Store in a cool, dry place between 5°C and 40°C.
- Keep away from direct sunlight, excessive heat, and humidity.
- Keep strips in the original vial with the cap tightly sealed after each use.
- Do not refrigerate or freeze.
- Do not wipe strips with water, alcohol, or any cleaning agent.
- Keep out of reach of children.
Warnings and Precautions
- For in vitro diagnostic use only — for external testing of blood samples outside the body.
- For single use only. Do not reuse strips — reuse causes inaccurate results.
- These strips are compatible only with On Call® PLUS and On Call® EZ II meters. Do not use with other meters.
- Do not use strips after the expiry date printed on the vial or outer packaging.
- Do not use strips from a damaged or previously opened package.
- Blood glucose results should be interpreted in the context of symptoms and clinical guidance. Consult a healthcare professional before making treatment decisions based on readings.
- Keep out of reach of children.

Frequently Asked Questions
Which meters are these test strips compatible with?
These strips are designed exclusively for use with the On Call® PLUS and On Call® EZ II blood glucose meters. They are not compatible with other On Call meters or other brands.
How much blood do these strips require?
Each strip requires only 1 µL of blood — a very small sample obtainable from a fingertip, palm, or forearm prick. The meter beeps to confirm sufficient sample has been applied.
How long does it take to get a result?
Results appear in approximately 10 seconds after the blood sample is applied to the test strip.
What does Code 690 mean?
Code 690 is a calibration code that identifies the specific batch chemistry of the test strips. The On Call PLUS and EZ II meters use this code to calibrate the reading accurately. These strips are pre-coded — no manual entry is required; simply insert the strip and the system calibrates automatically.
Are the results plasma-equivalent?
Yes. The On Call PLUS system reports plasma-equivalent glucose values — consistent with the reference standards used in laboratory blood tests, making results easier to compare with clinic readings.
Can I test from sites other than my fingertip?
Yes. These strips support alternative site testing from the palm and forearm in addition to the fingertip. Be aware that readings from alternative sites may differ during periods of rapidly changing glucose levels. Consult your healthcare provider for guidance.
How should I store these test strips?
Store in the original sealed vial at 5°C to 40°C in a cool, dry place. Keep the cap tightly closed after removing each strip. Do not refrigerate, freeze, or expose to direct sunlight.
