All about Lancets & Your Lancet Device

  • Last updated December 2, 2017

Where can I get lancets?

Lancets are very easy to find and inexpensive to purchase at any local pharmacy or drugstore. When seeking lancets, buy a brand that works with generic device, usually called a universal lancet, and is twist-top.

Most 28- 30 gauge lancets fit our meter. We’ve tried the following brands and all of them fit the Keto-Mojo meter:

    • TRUEplus Universal Twist top
    • EasyTouch Twist Lancets
    • One Step Twist Top Single Use Lancets
    • Fora Lancets 

How many times can I use a lancet?

We highly recommend using each lancet only a single time because it is safer and less painful. A lancet is only sterile for the first use. Every time you use the lancet, it gets a little bit more dull. And, a dirty lancet could contaminate your test results.

Fortunately, lancets are easy to find and very affordable.

How do I use the lancet device?

Our lancet device, which comes with every Keto-Mojo kit, looks like a fat pen and is your tool for getting the blood sample you need for a Keto-Mojo glucose or ketone test. Using it is quite easy. So much so that you can learn pretty much everything you need to know by watching this short video! If you still need some tips after watching the video, read on.

  1. Prepare your sample site: Before you test, wash your hands with warm, soapy water. Rinse and dry with a clean paper towel. Alternatively, you can use an alcohol swab to cleanse the area you plan to draw blood from and let it dry.
  2. Remove the white cap on of the Keto-Mojo lancet device by twisting it to the right.
  3. Insert a sterile lancet into the lancing device: Insert the lancet into the holder and push in firmly. Twist the protective disk on top until it separates from the lancet and save the disk for helping with safe lancet disposal later. Do not twist the lancet. You may need to straighten the lancet manually.
  4. Replace the cap of  lancet device by snapping it back on to the left.  It may seem like it won’t snap. This is normal,  just twist.
  5. Adjust the depth setting: The lancet device has six puncture-depth settings,  Smaller numbers are for a shallower puncture, and larger numbers are for a deeper puncture. Shallower punctures work for children and some adults. Deeper punctures work well for people with thick or callused skin. Twist the cap to set the device to your preferred setting. A shallower puncture may be less painful. Try a shallower setting first and increase the depth until you find the one deep enough to get a blood sample with enough volume.
  6. Prepare the lancing device for activation: Pull the grey knob at the end of the device until it clicks. You will see an orange color in the button on the side of the of the lancet device.
  7. Puncture your finger: Hold the lancet device firmly against the side of your finger. Press the clear button on the side of the device (with the orange glow) to initiate a quick, relatively painless puncture.  Remove the lancing device from your finger.
  8. Get a round drop of blood: Gently squeeze or massage your fingertip until a round drop of blood appears on your fingertip. If the blood smears or runs, do not use that sample. Dry the area and gently squeeze another drop of blood or puncture a new site.

How do I properly dispose of my used lancets?

According to the Environmental Protection Agency, lancets are medical wastes called “sharps.” Sharps can be dangerous to those handling garbage, if the sharps are thrown in the regular trash. ”Sharps boxes” are recommended for home use. Many pharmacies sell sharps boxes at reasonable prices and will allow you to return the boxes when they’re full.

General Guidelines for Sharps Disposal

    • Use a sharps box if one is available. Some hospitals and clinics also provide or sell sharps boxes.
    • If you don’t have a sharps box, use a hard (puncture-proof) non-clear container for storing used lancets.
    • When your container is full, dispose of the lancets at a local pharmacy, hospital, or clinic. (See below for more disposal information.)
    • When traveling, it’s still important to properly dispose of your lancets as suggested above, or bring your used sharps home for disposal.

Safety Precautions

    • Do not drop your used  lancets into the regular trash.
    • Do not use clear plastic bottles for lancet disposal.
    • Do not put plastic bottles filled with lancets in recycle bins.

Per the CDC, as of now, each state and region has its own rules for disposing of syringes, pen needles, lancets, and blood strips. To learn more about the regulations, you can check with your refuse company or the local waste authority. For additional information about how to safely dispose of your medical waste in your neighborhood, visit the Center of Disease Control and Prevention official website.

But in general, never dispose of medical waste directly in usual trash bins or public trash areas. Even when you are traveling, please use proper containers to collect your medical waste. Regarding test-strip disposal, patients typically dispose of them in the same bio-waste container as other medical waste items. Some like to keep the blood glucose test strips in a sealed bag and then place them in the sharps container. Sometimes, your community may have dedicated collection sites for filled sharp containers. Some of these locations that may collect them include police stations, fire departments, doctors’ offices, health clinics, health departments, pharmacies, and hospitals.

    First of all I would like to say superb blog! I had a quick question which I’d
    like to ask if you do not mind. I was interested to know
    how you center yourself and clear your thoughts prior to writing.
    I’ve had a tough time clearing my mind in getting my ideas out.

    I truly do enjoy writing but it just seems like the first 10 to 15 minutes tend to be wasted just trying to figure
    out how to begin. Any recommendations or tips? Thanks!

    I’m not sure where you are getting your information, but good
    topic. I needs to spend some time learning more or understanding more.
    Thanks for fantastic info I was looking for this information for my mission.

  18. Im obliged for the blog post. Want more.

  19. I am using the new Keto-Mojo GK+with the 30g lancets. These lancets appear to be thinner and hurts much less than the other blue ones ( don’t know the name). I want to know are the new lancets different than the older ones or is the difference between the newer shooter device compared to the older shooter device? And where can I specifically get more of the newer 30g lancets? Thank you

  20. How do you clean the insert where the lancet goes, when it’s been somehow contaminated? (Getting a E2 error constantly, after the keto mojo insert area was exposed to a drop of blood on the lancet- we didn’t see it until too late)

    Can’t find ANY advice online about how to clean this area

  21. Really enjoyed this blog.Really looking forward to read more. Great.

  22. 1 The lancing device won’t cock after the lancet is installed.
    2 you have no directions about how to position the lancet in the hole. What has to line up with what?

    great and i can assume you’re an expert on this subject.
    Fine with your permission allow me to grab your feed to keep up to date with forthcoming post.
    Thanks a million and please keep up the rewarding work.

  25. Hello I would like to know in some of the reading about your product it says it test blood sugar and ketones with 1 test strip. Is the correct and how many test strips do you get when you need more. Thank you

  26. Looking for a setting guide. Example: Is 1 on the lancet setting the strongest setting and 5 is the weakest or vice versa?
    That would be nice to know beforehand without having to waste needles.

    Thank you.

  27. I just received my GK+ update today and the envelope for the recycling of the old unit. However, I still have many strips that are still good for my old unit. I believe these are not comparable with the GK+ so I would like to keep using the old unit until I use all the strips. How much time do I have to send the old unit?

    Hi! This is kind of off topic but I need some
    help from an established blog. Is it hard to set up your
    own blog? I’m not very techincal but I can figure things out pretty fast.
    I’m thinking about creating my own but I’m not sure where to start.
    Do you have any tips or suggestions? Appreciate it

  29. Could I prick any place else on my body besides my finger like with some micro glucose meters?

  30. You made some good points there. I did a search on the issue and found most people will consent with your site.

  31. Help have had this unit for some time but I can not get unit to operate.
    Lancet ‘gun’ not popping needle out and no lights on on the TD-4279.
    Can someone please call me at 434-984-6040. We need to monitor my husbands blood sugar.

    If some one desires to be updated with most recent technologies therefore he must be pay a visit this website and be up to date every day.

  34. HI! Can you please let me know which lancets I need to order for the GK+ that I just purchased?

  35. I started the Virta program Monday. I never tested blood sugar previous. I loaded lancet, set it on 3, the needle never reached my finger, tried 4 and that didn’t do anything. 5 barely touches skin and can hardly get enough blood for one test. I think it is defective.

  36. I want to know where I can purchase the lancets that came with the meter. I found other lancets hurt my finger.

  37. I want to buy lancets. for the keto mojo meter Where can I find it

  38. Can the glucose and ketone readings be done with a single stick?

  39. Showing old device. New lancet device that shipped Oct 2020. uses different lancets. No marking or resources as to how to get the new lancets.
    Very annoying. I actually like the new device and lancets but you have stripped any markings to identify and purchase. There is no product on your site to replace.

  40. Where on you website can I purchase 30G lancets?

  41. I received the mew GK+ today. I have elderly thin skin and after repeated attempts the lancet set on 5 it barely made a drop of blood with squeezing.
    Also, the globose test strips worked via sipping , when I did the TEST drop.
    BUT repeated attempts (5) the KETO test strips DID NOT SIP my blood sample and DID NOT SIP the TEST drop! Very frustrating and a waste of test strips? Humph !

  42. My pen has failed to trigger in order to move the lancet. No matter what I do I cannot seem to fix the issue. The orange is always showing through the window no matter what I do. I’m not sure how it is already broken I’ve only used it a handful if times.
