NIPRO 4Sure Level 2 B-Ketone Control Solution (4ml). For use with DS02846 - 4Sure Smart Duo B-Ketone & Blood Glucose Monitoring System
The operation of the control solution test is similar to a blood glucose test except that this solution contains a known amount of β-Ketone that reacts with the 4SURE β-Ketone test strips and is used to ensure your meter and test strips are working correctly.
Only use 4 SURE β-Ketone control solution to perform a β-Ketone control test.
When to perform a Control Solution Test:
- There is suspicion the device or test strips are not working properly
- The B-Ketone test results are not consistent, or think the results are inaccurate
- The device may have been dropped or damaged
4SURE B-Ketone control solution only performs a β-ketone control test on a Nipro 4SURE Smart Duo Meter.
