On Call EZ II Blood Glucose Meter

On Call EZ II Blood Glucose Meter is a blood glucose self-monitoring meter manufactured by ACON Laboratories.

Regulatory sourcing note: despite a real search effort, no FDA 510(k) clearance record specifically naming "On Call EZ II" could be located. The device does not appear in ACON's current officially-marketed US product lineup, which suggests it is an export/legacy device sold primarily in markets such as Bangladesh rather than actively promoted in the US. This listing does not state or imply FDA clearance for this specific device. An independent device-evaluation database (Medaval) notes it found no peer-reviewed clinical validation data for this meter's technology at the time of its review. Buyers should rely on the manufacturer's included user manual and any locally applicable regulatory approval for clinical use guidance.

Key Features

• Blood glucose meter using glucose oxidase enzyme technology, per manufacturer specifications, designed to reduce interference from maltose and galactose in the blood sample

• Sample size approximately 0.5 microlitres of fresh capillary whole blood, per manufacturer specifications
• Measurement range approximately 20-600 mg/dL (1.1-33.3 mmol/L) and hematocrit compensation range approximately 25-60%, per manufacturer specifications
• Result time approximately 10 seconds, per manufacturer specifications
• Memory capacity of approximately 100 stored results, per manufacturer specifications
• Typical retail kit includes the meter, test strips, a code chip, control solution (noted as optional by one retailer), sterile lancets, a lancing device, carrying case, user manual, quick reference guide, and warranty card, per a Bangladesh retailer's pack-contents listing

Who Can Use This Product

• Individuals who have been advised by a healthcare provider to self-monitor blood glucose at home
• This device is intended for single-patient self-testing use, consistent with standard practice for this category of home glucose meter, though a device-specific instructions-for-use document confirming this was not located
• Not a substitute for professional diagnosis; results should be discussed with a healthcare provider, particularly if readings seem inconsistent with symptoms

How to Use

Follow the instructions included in the product's user manual for inserting the code chip, inserting a test strip, obtaining a blood sample with the lancing device, and applying the sample to the strip. Use only test strips designed for this meter -- some Bangladesh and regional retailers indicate this meter's strips are cross-compatible with the "On Call Plus" system, but buyers should confirm compatibility against the specific strip packaging before use.

Storage & Safety

Store the meter, test strips, and control solution in a cool, dry place away from direct sunlight and extreme temperatures, per the strip packaging guidance found for this product family. Keep test strip vials tightly closed and check expiry dates before use. Keep out of reach of children. This device and its test strips have not been confirmed as suitable for critically ill, severely dehydrated, or hyperosmolar patients, or for diagnosing or screening diabetes on their own -- consult a healthcare provider for guidance on appropriate use. Device-specific safety warnings beyond this general guidance were not located; refer to the manufacturer's included user manual for complete safety information.
