2. Understanding the Calibration Code Chip

Unlike auto-coding systems (such as the On Call Extra), the On Call Plus system utilizes a dedicated calibration code chip included inside every fresh box of test strips.

  • Why Coding is Necessary: Each manufactured batch of test strips possesses minor chemical variations in enzyme coating. The code chip calibrates the meter's optical/electrical sensors to that specific batch.

  • How to Code: With the meter powered off, insert the code chip firmly into the code chip slot. Turn on the meter; ensure the code number displayed matches the 3-digit number printed on the strip vial (e.g., Code 007).

3. Step-by-Step Blood Glucose Testing Procedure

  1. Hygiene & Site Prep: Wash hands with warm water and soap; dry thoroughly. Avoid using scented hand sanitizers or alcohol rubs immediately before testing, as residual chemicals can artificially inflate readings.

  2. Insert the Strip: Insert a clean On Call Plus test strip into the test port. The meter powers on automatically, confirming the batch code number and displaying a flashing blood drop icon.

  3. Obtain Blood Sample: Using a sterile lancet in your lancing device, puncture the side of your fingertip. Lightly squeeze to form a round $1.0\ \mu\text{L}$ droplet.

  4. Sample Application: Touch the edge of the strip's sample application channel to the blood drop. Capillary action will automatically pull the blood into the reaction chamber.

  5. Read & Record Results: The meter counts down from 10 to 1 and displays your blood sugar in $\text{mg/dL}$. Eject the used strip safely into a sharps container.

4. Common Error Codes & Troubleshooting

Error Code Probable Cause Corrective Action
E-1 / E-4 Missing or incorrect code chip; strip inserted backward. Ensure code chip is seated fully and matches the vial label.
E-2 Blood sample applied before prompt or insufficient volume. Retest with a fresh strip; apply blood only when the droplet icon flashes.
E-5 / E-6 Ambient temperature outside operating range ($5^\circ\text{C}\text{–}45^\circ\text{C}$). Move to a temperature-controlled room and wait 15 minutes before testing.
HI / LO Blood glucose exceeds $600\text{ mg/dL}$ or drops below $20\text{ mg/dL}$. Immediate medical emergency protocol required; verify with clinic.

Frequently Asked Questions (FAQs)

1. Are On Call Plus test strips compatible with the On Call Extra glucometer?

No. On Call Plus test strips work only with On Call Plus and On Call EZ II meters. They are not compatible with On Call Extra or On Call Extra Voice meters, which require auto-coding strips.

2. How do I calibrate the meter when opening a new box of strips?

Insert the black calibration code chip found inside the new strip box into the code chip slot on the side of the meter. Verify that the 3-digit code on the LCD matches the number on the strip vial.

3. How much blood sample is required for an On Call Plus test?

The test requires a 1.0 µL sample of fresh capillary whole blood.

4. How long does the On Call Plus glucometer take to display results?

The device delivers accurate blood glucose readings in 10 seconds following adequate sample absorption.

5. What pack sizes are available for On Call Plus test strips?

On Call Plus test strips are available in standard consumer retail packs of 50 strips (2 vials of 25) as well as bulk hospital packs of 200 strips (8 vials of 25) for high-frequency testing and clinics.

6. Can I reuse an On Call Plus test strip?

No. All biosensor glucose test strips are strictly single-use in-vitro diagnostic disposables. Reusing strips will result in chemical contamination and invalid readings.

7. How should I store On Call Plus test strips to maintain accuracy?

Store strips in their original tightly capped vial at $2^\circ\text{C}$ to $30^\circ\text{C}$ ($36^\circ\text{F}$ to $86^\circ\text{F}$). Protect from extreme heat, direct sunlight, and humidity. Do not freeze.

8. Does the On Call Plus meter store historical readings?

Yes. The meter stores up to 300 test results with date and time stamps, and provides 7, 14, and 30-day averages for general, pre-meal, and post-meal tracking.

9. Can I perform Alternate Site Testing (AST) with On Call Plus?

Yes. Blood samples can be taken from the forearm or palm during stable glucose periods. For immediate post-meal or post-insulin checks, fingertip sampling is recommended.

10. Where can I buy genuine On Call Plus glucometer strips in India?

You can order 100% authentic, fresh-batch On Call Plus Blood Glucose Test Strips (Pack of 50) online with secure payment, cash on delivery options, and fast nationwide delivery from Microsidd India.
