A distinctive feature of the On Call Extra system is its short re-dosing capability.
If the first blood application is insufficient and the meter has not begun its normal countdown, the system allows a second blood application within the manufacturer-specified short window, approximately 3 seconds.
This feature can help reduce unnecessary strip wastage when the first sample is slightly insufficient.
It does not mean that blood can be repeatedly added to the same strip.
Once the test countdown has begun, do not continue adding blood.
