GK+ Control Solution Ranges

  • Last updated January 18, 2021

Did you mistakenly throw away or lose your meter kit box or your strip box?

No problem, we’ve got you covered!


If you’ve purchased a GK+ meter kit, you’ll find glucose and ketone strips inside. On the back of the strip wrapper, you will find a LOT number. That number corresponds to Control Solution ranges printed on the bottom of your meter kit box. Similarly, if you’ve purchased a box of glucose strips, ketone strips, or the Combo Pack of strips, your control ranges are printed on that box.

If you no longer have access to your meter kit box or strip box, you can enter the LOT number of your strips in the form below and we’ll tell you what your control ranges are. The glucose lot number will differ from the ketone lot number, and you’ll get the control range for both Level 2 and Level 3 solutions (control solutions were provided with your meter kit or can be purchased separately).

Write down these ranges and keep them in your meter kit accessory case. Keep in mind however that each time you purchase new strips, your control ranges may change. Be sure to keep any new strip boxes for reference.

  1. I entered the Ketone lot number but this tool says it’s invalid. I’ve triple checked it and it was entered correctly

  2. It’s not clear. My meter recognizes that I used my control solution and the reading shows 105 but the range on the box is too big 96 to136. That is not telling me if my meter is accurately reading. I was checking it today because my blood glucose is abnormally low in the 50’s and my ketones are abnormally high at 1.9

  3. Did not acknowledge the number, correctly entered from the test strip.

  4. 1. I don’t know what the numbers mean.
    2. The bottoms of the numbers were cut off.

  5. On iPhone/ ketone results for level 2 and level 3 are cut off and not completely visible
    I got my glucose strips while traveling in Europe and they don’t provide a test result.
