THE EDGE Control Solution

The purpose of the control solution check is to validate the performance of the EDGE Blood Lactate Analyser using a standard solution with a known concentration range of lactate. A control solution test that falls within the acceptable range indicates the user’s technique is appropriate, and both the meter and the test strip are functioning properly.

Perform a control solution test:

  • Whenever there is doubt that the meter or the test strips are not working properly.
  • If the meter has been dropped, stored below -10°C (14°F) or above 55°C (131°F), or stored in humidity levels above 95%.
  • If the test strip bottle has been left open or has been exposed to temperatures below 4°C (39.2°F) or above 30°C (86°F) and/or light or humidity levels above 85%.
  • If the readings appear to be abnormally high or low.


  • The acceptable range for the control solution is listed on the package of test strips.
  • Use only the recommended lactate control solutions.
  • Always check the expiration date. DO NOT use control solutions if expired.
  • If a control solution test is not within the expected range that is printed on the test strip package, DO NOT use the Meter System to test. Repeat the test until a control solution test performs within the expected range. If the results continue falling outside the expected range, call the authorized dealer for service.
  • DO NOT touch the test area with the tip containing control solution.
  • DO NOT apply a second drop of control solution to the test strip.
  • DO NOT smear the control solution with the tip containing control solution.
  • Please refer to your control solution's package insert for additional information.
