Control Solution

  • Last updated December 5, 2017

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.

  4. I was looking for the reading limits. An actual number to compare to.

  5. I have recently purchased a keto mojo and it seems to be malfunctioning. When testing my glucose levels they are unusually high (up to 240) I’ve tired using the control solution (it was 117) but no where do I see a range listed on the vile???? I also wear a CGM and my sugars have been consistent . When the keto mojo reading was 240 my CGM was reading under 100.

  6. The kit does not give the range for the control results

    Wonderful items from you, man. I have remember your stuff previous to and you’re
    simply too fantastic. I actually like what you’ve received here,
    certainly like what you are stating and the way by which you say it.
    You make it enjoyable and you continue to take care of to keep
    it smart. I can’t wait to learn much more
    from you. This is actually a great site. help refuges

  8. You will find the range corresponding to this code on your strips under control solution range.

    I am having a hard time checking the range.
    Return I can’t find the range.

  9. Just put the darned info ON the website. Why did I look here, if you aren’t going to bother to put the info where it belongs? Telling me – go look on the box is not helpful nor is it customer focued.

    It would not be hard for you to simply put the required information here. Expecting your customers… who have purchased your product… gone to your website… searched for answers… to go yet another step to go look at the manual and the box is just plain silliness.

  10. can’t find where or how to locate the range for my test solution. Please include a picture of the small bottle and where on it the name is, and a picture of where to find the range? Confused and feel like I waisted test strips.

    platform are you using for this site? I’m getting tired of WordPress
    because I’ve had issues with hackers and I’m looking at options for another platform.
    I would be great if you could point me in the direction of a

    Do you have any advice to help fix this problem?

  30. does not match what the vials say on bottle. vials dont say any of above. what should the meter read when testing?

  31. The control solutions I received with my device don’t list what the measurement should be. Only an expiration date. I can’t tell if the device is in alignment with the control solutions.

  32. Really informative article. Really Cool.

  33. Just starting out and need all the help I can get.

  34. I want to know when I should use control solution 3.

  35. pick up the phone and help customers. cool. thanks.

  36. Trying to find the ranges to compare the results of my control solution tests. I am told the ranges are on the test strip vials. My meter and first set of strips didn’t come with test strip vials. I have results but no chart to which I can compare them.

    If some one wishes to be updated with hottest technologies then he must be go to see this site and be up to date all the

  38. What should the control number be when testing the glucose solution? It is not labeled on the strips that came with me Keto mojo and I don’t think it’s working right

  39. I am unable to find the control system range on the strips or the vials. Both of my vials indicate level 2.

  40. your instructions say: 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.

    So far, I’ve tested ketones. I see on bottle of solution “Level 2” … so maybe that’s L2??? BUT the box doesn’t show L1 or L2 for ketones. It shows CTRL 2 and CTRL 3. So, no L at all. AND 1,2 not 2,3. I have no idea if I my ketones are accurate or not

    I just had one of my highest ketone readings today of 1.9 …which was surprising based on what I ate yesterday AND that I’ve had trouble getting into ketosis since Dec 23.

    Yesterday, I had an very unusually high glucose 1st reading of the day of 140. That’s when I started wanting to do the control. But didn’t get around it

    I appreciate you’re asking my name and email. Hope you’ll get back. I’m looking at the control info for the glucose now. Thank you

  41. Thank you for your post.Really thank you! Great.

  42. There is no control test range listed on vials of control solution.

  44. It didn’t tell us the standard deviation of the control solution. Nor did it tell us that it had to have an exact reading. As an Analytical Chemist, this help guide was severely disappointing. Do better!

    This site is one thing that’s needed on the internet, someone with a little originality!

  47. Not very informative on how keto mojo strips, solution and meter work, ranges, how, etc. Shouldn’t be hard to consolidate that information.

    The clarity in your post is simply nice and i could assume you are an expert

    Hello, just wanted to say, I loved this post. It was inspiring.
    Keep on posting!

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

  51. 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.

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

  53. 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.

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

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

  56. 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.

  57. 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!

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

  61. 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?

  62. 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.

  63. 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.

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

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

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

    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.

  68. 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.

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

    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.

    Nice blog here! Also your web site loads up very fast!

    What host are you using? Can I get your affiliate link to your host?
    I wish my website loaded up as quickly as yours

  81. 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?

  82. 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

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

    Bottle doesn’t have it in side either

  84. 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?

  85. 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.

  86. 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.

  87. 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?

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

  89. 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.

  90. 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.

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