Final answer:
The code on the glucose test strip should be compared to the code on the glucometer when the strip is placed in the meter.
Step-by-step explanation:
The code on the glucose test strip should be compared to the code on the glucometer when the strip is placed in the meter. This is because the code on the strip container may not always match the code on the individual test strip inside. By comparing the codes after inserting the strip in the meter, you ensure that the correct calibration code is used for accurate blood glucose measurement.
