The On Call Ketone Monitor, also known as the On Call GK Dual, is a portable blood monitoring system designed for measuring blood β-ketones (beta-hydroxybutyrate) and blood glucose using their respective compatible test strips.
Manufactured by ACON Laboratories, the On Call GK Dual combines ketone and glucose testing capability in a single compact meter. The device is particularly useful for people who need to monitor blood ketone levels as part of an appropriate healthcare or diabetes-management plan.
For ketone testing, the meter uses On Call Blood Ketone Test Strips and provides a ketone result in approximately 10 seconds. For compatible glucose testing, results are available in approximately 5 seconds.
The monitor also incorporates useful everyday features including hypoglycemia, hyperglycemia and ketone warning functions, meal markers, five customizable testing reminders, a strip ejector and automatic shut-off.
The Microsidd starter pack includes:

A major advantage of the On Call GK Dual is that it consolidates two types of monitoring into one portable system.
Instead of requiring a dedicated meter for glucose and another meter for blood ketones, compatible glucose and β-ketone test strips can be used with the same GK Dual meter.
This makes the system particularly useful for users who already need regular glucose monitoring but also require access to blood ketone testing when appropriate.
The On Call Ketone Monitor may be suitable for people who:
For people with diabetes, significant ketone readings—particularly when associated with high blood glucose or symptoms of illness—may require prompt medical assessment. Follow the action plan provided by your healthcare professional.
For blood ketone testing, insert a compatible On Call Blood Ketone Test Strip into the meter and follow the manufacturer's instructions for obtaining and applying the required blood sample. The meter analyzes the sample and displays the ketone result in approximately 10 seconds.
For blood glucose testing, use only a glucose strip specifically compatible with the GK Dual and follow its corresponding instructions. Glucose results are displayed in approximately 5 seconds.
Always refer to the current user manual and test-strip instructions rather than relying solely on a website summary.
