Control Solution

What is control solution?

Control solutions are a way to test your meter so you know that it is giving you accurate results. However, it’s very rare to need a control solution for a Keto-Mojo meter, as our meters seldom fall out of calibration. That said, we include information about control solutions in our manual so you will know you have a way to benchmark if you feel your meter is not working properly. Our control solutions contain a known amount of β-Ketone or Glucose that can react with Keto-Mojo test strips.

Am I missing control solution from my Keto-Mojo kit?

No, you’re not missing control solutions from your Keto-Mojo kit. Although the Keto-Mojo manual suggests testing with control solutions, this is not necessary because all Keto-Mojo meters are calibrated for control before they leave the factory. You don’t have to worry about the Keto-Mojo’s accuracy once you receive it.  If you suspect your meter is giving you inaccurate readings outside the accepted variance (click for details on glucose or ketone variance), please contact customer support and we will help you get to the bottom of the problem.

When should the control solution test be performed?

If you suspect your meter has been dropped or damaged, or you suspect your meter or strips are not giving you accurate readings, you may want to perform a control test. You can purchase control solutions on our website here, and perform a test. If your test results are not within the control range, please contact customer support and we will determine if you are eligible for a replacement.

How do I use the control solutions?

  1. Make sure you have your meter, an unused test strip, and the control solution.
  2.  Insert a glucose or ketone test strip to turn on your meter.  Wait for the meter to display the flashing blood droplet.
  3. Shake the control solution vial thoroughly. Squeeze out a drop of solution on to the tip of the vial cap and wipe it off. Then squeeze out another drop onto the tip of the vial cap. With the strip in the meter, gently move the tip of the test strip to the control solution droplet and hold there until strip fills completely and the meter begins to count down.
    • To avoid contaminating the control solution, do not apply control solution directly from the bottle onto a strip.
    • NOTE: Your device will tag this measurement as QC test automatically.
  4. After counting down, the meter will display the test result. Compare this result with the range printed on the side of your strip vial;  if the results fall within the range, your meter is working properly. If the results do not fall within the range, please read the instructions again and repeat the control solution test. If the results are still outside of the range, contact customer support
  5. Whenever “QC”is displayed, your meter recognized that this was test result and will store your test result in memory under “QC,” not in your personal readings.

Note: Each bottle of control solution has a code written on the bottle.  Ketones;  L1 or L2.   Glucose W2 or B3.  You will find the range corresponding to this code on your strips under control solution range.

Please refer to the Owner’s Manual that came with your meter or download it here for complete testing instructions.

Do Control Solutions expire?

Yes. Control solutions have a shelf life of 12- 18 months (this expiration is printed on the bottle) or 90 days from when it was first opened, whichever is sooner.

  1. There is no control range on my strips. They are individually packaged.

  2. my solution does not say either of these markings. I can not find what the expected range should be while testing the control solution. I also don’t know how to tell the meter not to include this as a reading, rather to treat it as a control test.

  3. It doesn’t say anywhere on the strips, the bottle, the box or the instructions as to the reading the monitor should have for the level 2 glucose solution. I also can’t find the levels on your website.

  4. Article doesn’t explain what control solution is for. Why do I need it? How do I know if it is working?

  5. Hi,

    I just received my glucose and ketone strips and want to test using the control solution. In the past the boxes that the strips came in had the acceptable range for the solution that I have, Control Solution 2. This box, which contains both the glucose and ketone strips does not have a sticker on it, identifying the correct ranges. The information inside the box didn’t have it either. So how do I know what the acceptable range is?

  6. My new meter and strips are testing outside of the control limits. I have Level 2 control solution and my bran new strips that came with the promo are testing at 3.0 and 3.1. Now I have no strips to accurately test my daughter with. Please advise.

  7. I still don’t understand what a correct control solution test result should be. I got a reading of 110 for glucose. Does that mean the meter is correctly calibrated or not? The article doesn’t explain how to know.

  8. I purchased a meter test kit that came with a solution and K and G strips. The K control solution is L2, nowhere on the strips is the range printed. How do I know if my test failed?

  9. Can’t find what range test solution is supposed to be

    Bottle doesn’t have it in side either

  10. My glucose test solution only has level 2 on it and it came back with a reading of 1.19 so no where in you description above does it tell me what I’m looking for

  11. I need to get new control solutions for glucose and ketones for the old TD-4279 Meter, which don’t seem to be available on your site anymore. Are there other equivalent solutions that could be used?

    Hi would you mind sharing which blog platform you’re using?
    I’m planning to start my own blog in the near future but I’m having
    a tough time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design and style seems different then most blogs and I’m looking for something completely unique.

    P.S Sorry for getting off-topic but I had to ask!

  16. What is the control test result expected to be? How do I know of it is accurate?

    That is really attention-grabbing, You are a very professional blogger.
    I’ve joined your feed and look forward to in quest of extra of your excellent post.
    Additionally, I have shared your website in my social networks asmr 0mniartist

    I’ve been browsing online more than three hours today, yet I by no means discovered any attention-grabbing article like yours.
    It is lovely worth enough for me. In my opinion,
    if all web owners and bloggers made just right content as
    you probably did, the web might be much more helpful than ever before.

  21. What is the strip vial ????
    What should the meter be reading when using a control, where is that information displayed ?

    I love it whenever people come together and share opinions.
    Great site, stick with it!

  23. No range listed anywhere! Can’t correspond the “level” to a blood sugar range

  24. I did not see a range on the strip vial, to compare and see if the control test was within range. When I preformed the test, it came up as 120, and did recognize that it was the control solution.

    My spouse and I stumbled over here coming from a different web address and thought I may
    as well check things out. I like what I see so now i’m following you.
    Look forward to looking into your web page yet again.

  26. I searched for info on printing data and it went to this page which had nothing to do with printing.

  27. My bottle of glucose control solution does not have W2 or B3 on it. It says “level 2” and has a lot and exp.

  28. If I threw the box away how can I get the control range for my strips

  29. I do not understand what the expected reading should be based on these directions. Each bottle says 2mL, BG, BK. My glucose reade said 99, while BK said 2.5.

  30. The test strips that came in my meter case do not have control values listed on them as they’re not in a box. Further, this statement is misleading: “Each bottle of control solution has a code written on the bottle. Ketones; L1 or L2. Glucose W2 or B3,” as the Glucose control says “Level 2” with no mention of W2 or B3. Either I received out-of-date products, or the information on this page should be updated.

  31. Received a level 2 glucose and level 2 ketone control solution. Ran control test but have nothing to compare results. What should the range of results be in for the unit is in compliance with accuracy?

  32. can’t figure out what the level2 glucose test solution should read

  33. Major thankies for the blog article.Thanks Again. Will read on…

  35. What are the ranges for control solutions. The printed materials say it’s printed on the test strip box or label (or on the test strip according to this page). I’ve looked in all these places and have not yet found anything that shows a corresponding range. This is very frustrating because it would be SO easy to just print the darn ranges in the instructions! Make things easy!

  36. What is the result supposed to be? What is a “strip vial?” The vial of test solution and the test strip are two different things. Neither has the result range. This is very frustrating.

  37. I can not find the numbers that correspond to the level 2 for the controls anywhere. Help!
    thank you

  38. You should give the ranges for the supplied strips and solution as the print on them is so small that it’s unreadable.

  39. I’m looking for the valid test ranges that I should be seeing as a result for the control solutions for ketone and glucose. Thanks.

  40. Where do I find the glucose control range on the new foil sealed strips?

  41. These instructions do not match the labels on my control solution vials or range label on strips package. Both vials say Level 2. Also, the strips package have two sets of ranges for each of the Glucose and Keytone strips, each set containing ranges for Control 2 and Control 3. The manual instructions imply control 2 and 3 are for glucose and Keytone respectively. I can’t make any sense of this! Instructions need a lot of wordsmith for clarity and a help/demo video as well. Feels like a maze currently. Principle: Don’t make the customer feel stupid.

    Otherwise, impressed with product and website information.

  42. The Coding Solution instructions above do not apply to your current model meter
