GK+ Control Solution Ranges

  • Last updated September 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 am taking the number off my package and it say invalid! 😢

  2. Lot numbers on back of my straps do not come up as valid lots.

    Unable to view control ranges of straps. Control results don’t appear in sync.

  3. My lot number says it’s invalid but I’ve triple checked that the number on the test strip packet is correct.

  4. so i typed in the lot number from the box, and the back of the test strips, and got an “invalid lot number” message

    u210127

    how can I find the control range ?

  5. i put in the lot numbers and it is coming up invalid

    I tested my keto mojo as when I test myself ketos keep coming up Lo not saying that is wrong
    but when I tested w the solution I was informed my reading may be high

    Please advise as to what I should do next lot # ketone strips U210089
    glucose strips U210086

    I am looking to order more lancets and both strips but very hesitant if I am going to have to get another meter

    God Bless and
    Thank You so Much

  6. Received an error that my lot number was invalid, “Enter a valid Lot Number”. Just received my unit and wanted to perform a control test. There is no control ranges on the packets.

  7. I think my machine is off based on the numbers I’ve been receiving. I used brand new testing solution and at level 2 the numbers are 42 points higher than stated in the package insert and with level 3 they are 55 points lower than stated. I’m not sure how to proceed from here. Please let me know if this is fixable

  8. Your system did not find my lot number U210277

  9. It said invalid lot number for both and I entered them correctly.

  10. I enter the lot number of my glucose test strips and it says invalid lot number. I did it multiple times and it still does not work. I need to know what the range is for the glucose control solution for level two. The lot number is U210259

  11. My ketone strip lot number is U210293. But your silly website is indicating it is an invalid lot number. I’ve checked it 5 times now. So your website is simply pissing me off.

  12. It’s telling me my lot # is invalid

  13. I keep having a response on this page of “Enter a Valid Lot Number”. Glucose: U210284 Ketone: UEN20059

  14. When I entered my lot number to see what the control numbers are it said it was invalid, Please let me know how to verify if my machine is calibrated. Thank you

  15. The lot number on my test strips came in as a “invalid number” (U210288)
    …not sure what to do from here.

  16. I’m still very confused about how to calibrate my meter using these control solutions. I got some new strips and they seem inaccurate compared to the strips I had before. These regularly show my ketones as too low and my glucose too high, by around 15 points. I thought I remembered that we could calibrate these. I’ll keep looking to see if I can find the original instructions that came with the GK+ meter.

  17. I bought the kit with solutions and both strips in the kits there Lots keeps reading not valid. U210177… i’m trying to figure out if my meter is calibrated and don’t know the ranges???

  18. I enter the lot number exactly as it is shown and I get a message saying “enter a valid lot number”. It IS a valid lot number! My ketone strip lot number is U210212

  19. My lot numbers are from the keto mojo kit and it’s saying enter a valid lot number. These are valid lot numbers.

  20. Trying to do a control solution test. The lot number on the strip, U210038 comes up as invalid. When I do the control solution test, the meter simply reads “LO” I do not know what this means. I would guess it’s reading high, but am not sure how to test and/or calibrate it…

  21. Glucose lot number U210176
    Ketone lot number U210177

    I need the control ranges and the form above says my lot numbers are invalid.
    Thank you

  22. I typed in the lot number for glucose (U210288) and then for ketone strip (U210295) and it responded with “Enter Valid Lot Number” for each

  23. It says my lot number is not right…but it is on the package.

  24. You have a place to enter lot #s to look up control solution ranges: but you don’t provide the actual control solution ranges after we enter the lot numbers! There’s no enter button and hitting enter in either of the lot # edit fields does submit the information for a response either. PLEASE FIX THIS BUG!!!

  25. None of my lot numbers work

    U210242
    U210211. G
    U210259. G
    U210210. K

  26. 1. I put in the lot numbers but the control range did not come up!
    Here are my lot numbers:
    Glucose: 210418
    Ketone: 210419
    I need the control range for level 2

    2. How do I delete the test score from the device as it will alter my true averages?

  27. The lost number on my test strip can up invalid but I entered the correct lot number numerous times. Additionally, the instructions in the kit indicated the test range values would be on the test strip or box and they are not.

  28. Hi, I was trying to check if my meter is ok on the glucose end.

    I entered my lot number of U220035 and you said invalid.
    I ran a test from solution and it showed 122, but what does that mean? My solution is level 2?

  29. How in heck do you gave a control solution with such a wide range of 88 to 132 mg/dL? This apparently does not give a reading of what a within normal limits glucose is when non-keto?

  30. My lot number doesn’t give any result. It’s 210418, without a letter in front of it. I tried it with all letters of the alphabet by the way, but nothing works.

  31. I’m getting an error that my lot numbers are invalid. U210044 and U210045, both expire in 2023

  32. I could not find my control solution ranges for glucose.
    I used 220035 for glucose strips and was not found.
    Then I tried the lot number on the control solution UAN20104 and got the same response

  33. I’m entering my lot number and it is saying invalid
    U210286 exp 2023-09-18
    I just purchased

  34. I put my lot numbers on the site and it says nvalid. This is what is on the strip packages and purchase box!!

  35. Says invalid lot number but its literally what is on the strips

  36. I enter my lot number exactly and it states invalid number. Trying to find out what the control range is.

  37. The lot numbers come back as “invalid” but they are definitely correct

  38. I entered the lot number for the test strips to find the control solution ranges. It tells me I have entered an invalid lot number. It seems the system does not have information for newer test strips.

  39. I enter the lote number on the trips and “Enter a valid Lot Number” message appear, I check it like 5 time to make sure the lot is correct,,, also I enter the lot with and without the “U”

  40. Look up doesn’t work. My lot number comes back invalid. U210213

  41. To find the range for the Control Solution if the box is missing, please offer a search database for the Lot Number on the bottle of the Control Solution itself.

  42. Can’t use control lots. Care full entry of Ketone Lot U210006 = invalid. The control solutions; all four LEAKED in shipping. This is the second batch I’ve bought. NO instructions. Over all poor quality control. Difficult to use strips, hard to open, etc. Please e-mail back xbill@mac.com

  43. I have read all your directions and I can’t figure out what the number should be for the control solution it says it should be in number two what does that mean? The numbers won’t import I don’t understand can you just show us a chart or something.

    Please cut it out with the screen take over ads as well. Nobody likes them.

  44. Regarding the FAQ on how to look up the calibration number on “https://keto-mojo.com/help-docs/glucose-ketone-control-ranges/” . After entering a valid lot number on the testing strip package as instructed I received the “Enter a Valid Lot Number” error message. My lot numbers are: glucose strip – U210286 and ketone strip – U210293.

  45. The lot numbers I am entering are not valid:
    Ketone: U210140 and Glucose: U210137

  46. I entered the lot numbers for both multiple times and screen kept listing list a valid number. My Glucose and Keytone lots are U210211 and U210212

  47. Hi – I entered my glucose and ketone lot numbers but nothing happened. It didn’t give me the range for the solutions.

  48. Lot number on back of strips packaging was not found

  49. When I enter my glucose strip lot number above, I get a message saying to enter a valid lot number.

  50. Typed in both lot numbers for ketone and glucose. Both are “not valid.” These came with my new meter. Also, numerous ketone strips are missing. The package was sealed with no strip within, 5 missing in total.

  51. I put in the lot number for both the glucose strip and the ketone strip and they both said to enter in a valid Lot number, which I did. So, it was no help!

  52. There was no answer because it says my lot #’s are invalid. I double checked and they were typed in correctly.

  53. I’m entering the lot number from the back of the glucose test strip package and it just keeps saying “enter a valid lot number.” I’ve double checked it and I’m entering the correct lot number. I just want to know the control test range.

  54. I entered the lot number from the back of the ketone test strip wrapper. I get “enter a valid lot number” message.

  55. Says my lot number not valid. But, that’s what is printed on wrapper. Hmmmm.

  56. Hello,
    The following Lot number do not appear within the lookup to determine the test solutions range:
    Ketone: Lot#U210337
    Glucouse: Lot#U210338

    Could you provide me with the ranges for both? Thank you!

  57. Lot number didn’t work U210043 and my control solution doesn’t have a range

  58. It is saying my lot# is not vail that came with the box. Glucose lot # is U210137 and Ketone lot # is U210138

  59. I am trying to figure out the control range. I went to the website and it is pretty straight forward however when I put in lot code for both glucose and ketones it tells me invalided lot number. Lots numbers are below.

    Glucose Lot: U210215
    Ketones Lot: U210177

  60. Hi there,

    My keto mojo machine is giving me varied blood sugar results with each strip. It looks to be inaccurate. Which makes me wonder if my ketone strips are accurate too?

    I was trying to look up my ketone and glucose testing solution ranges to see if my meter is working correctly, but they said I have an invalid lot #?

    I’m very confused and dissatisfied because this machine wasn’t cheap!

    Please let me know what I can do.

    Thank you in advance,

    Kelly

  61. Lot# U21022 ketone strips shows as an invalid lot #

  62. Hi,
    I could not find the range for the test strips. The lot number is U210176 for glucose and U210178 for ketone. Thanks!

  63. My mojo is not working properly …says my control number is in valid …I just bought my mojo + a few months ago from you

    Help

  64. I typed in the number and it said it was invalid. U210370.

  65. Hello
    I have the older meter and would like to just purchase strips and the new meter. I don’t want to pay for things I don’t need. Can I purchase strips and meter? Or do you have old strips left? Thank you

  66. I entered my lot number exactly as it shows on the strip – U210038 – and it keeps saying invalid lot number.

  67. I can’t find the control range for L2 vial by using the lot number on my new ketone strips. They say U210004 but your search says invalid. I threw away the box so I don’t have the grey sticker.

  68. My blood sugars seem crazy out of control and I’m trying to use the control solutions but can’t find the sheet of ranges. Tried to use the page and it Jerrod telling me that my lot numbers on the strips aren’t valid

  69. My lot numbers are not “valid” for either of these entries. I have triple-checked by typing.
    Glucose: U210284
    Ketone: U210287

  70. I entered the lot # and it indicates invalid. Glucose U210086 Keto U210089

  71. Hi,
    I need the control values for glucose strips from the lot # U210176. The form above is saying it is not valid.

  72. LOT NUMBER COMES BACK INVALID HOW DO I KNOW MY TEST SOLUTION RANGE?

  73. I have glu strip lot number U210010 exo 3/26/23. I’m trying to confirm control range. System says number not valid.

  74. It didn’t tell me the range when I put in the lot numbers

  75. I put the lot number in, and it kicked it out saying enter valid lot number.

  76. Error “Enter a valid lot number”. Glucose lot number on my strip

  77. Error “Enter a valid lot number”. Glucose lot number on my strip is U210130

    Same error for ketone strips. Ketone lot number on my strip is U210129

  78. SAYS MY LOT NUMBER IS NOT VALID… BUT IT MOST CERTAINLY IS WHAT IS ON THE STRIPS…
    GLUCOSE U210043 KETONE U210046

  79. A typed in the ketone lot number: 210082, but it is not accepted and I cant see the control solution range.

  80. It does not accept the lot number.

    Lot number for glucose is 210079

    The reading I got for glucose test is 5.7.

    The lot numbers I have for both glucose and ketone strips are not long enough for your form.

  81. Error message says “Enter a valid Lot Number.” I am entering the correct number

  82. The above “control solution ranges” Lot number check is not acknowledging that the four separate lot numbers received in the latest bundle are even valid!

  83. Lot number U210176 give “Enter a valid Lot Number.”

  84. I have entered my lot number on the glucose strips and it keeps saying enter a valid number….I have!!!

  85. Both Lot numbers have been typed in correctly and both say the lot number is invalid. How can I get my ranges when this is saying the lot numbers are invalid when they’re not??

  86. It is telling me to enter a valid lot number when I’m precisely entered the correct lot number

  87. I put the correct lot numbers below. Response was they were invalid.
    Glucose lot:U210137
    Ketones lot:U210138
    Can you help me with this?
    Thank you

  88. My glucose strips indicate a lot number of U210033, and I get invalid lot number message when I enter.

  89. update your lot number faster–we’ve had this for months and your site says invalid lot. we triple checked we’re entering it correctly

  90. I tested my blood glucose this morning and got a reading of 173 and ketones of 2.3. I immediately retested and got a reading of 86 and a reading of hi for ketones. I then ran controls and got 106 for the glucose strip and 2.4 for ketone strip. Ketone strip lot #u210134 and glucose lot# u210132

  91. Last month I bought a new Keto-Mojo GK+ meter kit to replace my old meter.
    I am trying to learn more about the process, but when I enter the lot numbers on the strip packages I just get the message “Enter a valid lot number”, what’s wrong? The glucose lot number is U210176 exp: 2023-06-08,
    the ketone lot number is U210177 exp:2023-06-08.

  92. What is the damn concentration reading for the damn std?

  93. In this wide control test sample range how can you accurately convert to blood sample test.

  94. My ketone and glucose strips lot number is not showing up says invalid. Exp date is 4/16/23

  95. I am incredibly angry with the fact that you FORCED me to buy a new meter and it doesn’t sync correctly. I followed your directions exactly. But my lot number shows up as not being valid. The strips came with the meter for goodness sake.

    I want this fixed and I really hope you can help me.

  96. I recently bought glucose strips. The lot number comes up invalid.
    U210043

  97. im typing in the lot number, U210176, and it just says error. also i srill have all the papers that were in the box and cant find these ranges

  98. I am trying to find the test control level 2 numbers for my G+ device. The two test strip lot numbers I have are Glucose U210176 and Ketone U210177. Please tell me the range my meter should return for these test solutions level 2 Glucose UAN20085 and level 2 Ketone UEN20072.

  99. the lot numbers on the strips give me the message “Enter a valid lot number” and the number entered from the back of the strip case is correct.

  100. When I enter the the lot number out of the package in the above area it says non valid lot number

  101. Can’t figure out control test range for strips that came with kit. Ketone strip lot number U210177. When i enter says enter value lot number

  102. I am receiving an “invalid lot number” message when trying to find control range. The lot number is U210045

  103. Why is the range so big? If the range of error for my actual blood sugar is that wide, then that is concerning.

  104. I have inputted 2 boxes lotnumbersand thy have all come up as invalid.

  105. This does not answer any questions for me. Also, when I enter the lot numbers they do not work. I am positive they are not invalid but the site continues to tell me to enter a valid lot number. I enter U210012 for my glucose strip and U200222 my ketone strip and nothing. Also my real question was concerning what readings I should get with the control solution with lot numbers UAN20050 for the glucose solution, and UEN20036 for the ketone solution. Please help and fix the site to work properly.

  106. My ketone meter is reading below the range of the control solution and this does not give me any information about what that means or how to calibrate or do anything to make sure that my unit is reading accurately

    1.7 was reading
    1.8-2.8 is the printed range for the control

  107. On Chrome browser can’t see what the contour reading should be. Ketone strip is showing as invalid lot number

  108. Page doesn’t work – it doesn’t show the ranger!

  109. It does not recognize the lot numbers for my strips.

  110. This will not accept my lot numbers. Keeps prompting me to enter a valid Lot number

  111. Doesn’t recognize the number of the strips

  112. used many strips for testing the control solutions.

    Here is what the control solutions showed:
    Ketones .2
    Glucose Lo

    I tried many strips to no avail.

    FWIW, I am on a 4 day fast. Per this meter here are the results
    Ketones 7.1
    Glucose 45

    Help! do I have a faulty meter?

  113. I am trying to get what the range should be for my control solutions that came with my kit. If I enter the lot number it is coming up as not found.

  114. When I put in the strip number it says that it’s invalid, U210010.

  115. my ketone strips lot number printed on back of strip package is U200181, however your system is not recognizing it and in red states “enter a valid lot number”. i have quadruple checked that I am entering what is printed on the proper ketone strip package correctly but your system does not recognize it. my ketone test reading was 2.5, is my meter working? my glucose lot number is U200169 and test reading was 113. please let me know what is wrong and if my meter is working correctly.

  116. I can’t find the control solution numbers to calibrate my keto-mojo. When I enter the lot numbers from my glucose and ketone strips, your site says they are invalid lots numbers

  117. I’m typing in my lot number because I threw out the box and am trying to use the control solution and it’s saying enter valid lot number. U200180 ketone strips. My readings go from 2.4 to .4 to .2 in 5 seconds. I’m just wasting all the strips I bought at this point and I just got the GK+ monitor not long ago because you basically forced us to. It’s garbage compared to the original monitor I bought from you.

  118. The control ranges are wide. To me, it translates to Keto-Mojo measurements being inaccurate. Shouldn’t an accurate meter demonstrate a less variable reading using standardized control solutions? Thanks.

  119. the test strips that came with my keto mojo do not have a range anywhare on the packaging or strips so I have no idea if the control solution test results are in the range.

  120. Lot number for ketone test strips is shown as invalid (U200180).

  121. lot number is saying not valid. it was keyed in correctly. U200179 ketone strips

  122. 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.

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

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

  125. 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

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