There is one control solution. There is a table that is printed on the test strip label that represents the acceptable testing
range. Control solution is not supplied with the meter, it can be purchased separately by contacting Jana Care.
Gently shake vial of control solution. Perform a test using the same instructions as in the How to take a test section,
except using a drop of control solution instead of blood. Confirm that the result is within the range that is listed on the strip vial.
If the result is not within the specified range, then contact us at support@janacare.com
