Frequently Asked Questions

Everything you need to know about your GK+ meter, test strips, shipping, and more.

Getting Started

The difference between the GK+ and GKI meters is primarily regional.
  • The GK+ meter is sold in the United States and Canada.
  • The GKI meter is sold in international markets outside North America.
Both meters measure blood glucose and blood ketones.

The Glucose Ketone Index (GKI) is a calculated ratio based on your glucose and ketone readings. While the GK+ meter does not display GKI directly on the device screen, when connected to the MyMojoHealth app, the app can automatically calculate and display your GKI.

Please note that GK+ test strips and GKI test strips are not interchangeable. Be sure to purchase the strips designed specifically for your meter model.
The Keto-Mojo GK+ blood glucose and ketone meter is ideal for individuals who want actionable insight into their metabolic data.

The GK+ is FDA-cleared for at-home blood glucose self-monitoring, making it appropriate for individuals who regularly track blood sugar levels. It also offers blood ketone testing for broader metabolic awareness.

It is particularly useful for:
  • Individuals who monitor blood glucose as part of diabetes self-management, under the guidance of a healthcare professional
  • People following a ketogenic, low-carbohydrate, or fasting lifestyle who want to track nutritional ketosis
  • Individuals interested in tracking glucose and ketones as metabolic biomarkers
  • Health-conscious users who want to observe trends related to insulin sensitivity and metabolic flexibility
  • Clinicians, coaches, and researchers who incorporate patient-generated glucose and ketone data into education, coaching, or research programs
With dual glucose and ketone testing in one device, the GK+ helps users observe how factors such as food choices, fasting, stress, and activity influence their metabolic markers, supporting informed, data-driven lifestyle decisions.
Each meter kit includes the meter, a lancing device, lancets, starter test strips, a travel case, and user instructions.

Exact contents and quantities may vary by kit. Please refer to the specific product page for complete details.
To begin testing, you need:
  • The GK+ meter
  • Compatible glucose or ketone test strips
  • A lancing device and lancets
All kits include everything you need to begin testing. Additional test strips can be purchased separately as needed.
Yes. Blood glucose and blood ketone testing require different test strips.

Glucose strips and ketone strips are sold separately and are not interchangeable.
Only Keto-Mojo glucose test strips (brown) and Keto-Mojo ketone test strips (teal) are compatible with the GK+ meter.

Other brands are not compatible and will not function with the GK+ meter.
The number of test strips you need depends on how often you plan to test.

Many users test 1–3 times per day and adjust based on their routine and goals.

Test strips are sold in packages of 60, so you may wish to consider how long one box will last based on your expected testing frequency.
Keep the packaging sealed until use, and avoid exposure to heat, moisture, or direct sunlight.

Improper storage may affect the accuracy of your results.
The meter itself does not expire. However, certain testing supplies included in meter kits do have expiration dates.

Test Strips — Expiration date printed on each individual foil pouch. Shelf life varies based on manufacturing date and inventory rotation. For more information, see our Test Strip Expiration Page.

Control Solution — Expiration date printed on the bottle. Once opened, use within 90 days or by the printed expiration date, whichever comes first.

Lancets — Multi-year shelf life. Expiration date printed on the packaging.

Always check the printed expiration date before use. Using expired testing supplies may affect the accuracy of your results.

Using Your Meter

Most people are surprised by how little they feel. The lancing device is adjustable — you can dial the depth down to the minimum needed for a small blood drop. Many users describe it as a brief, mild pinch. With proper technique, most people find testing quick and virtually painless after the first few tries.
The Keto-Mojo GK+ meter is highly accurate and meets FDA requirements and ISO 15197:2013 performance standards for blood glucose testing.

In performance testing, 95% of glucose readings fall within ±15% of laboratory reference values, demonstrating reliable and clinically validated accuracy.

As with all finger-stick meters, small differences compared to lab tests or continuous glucose monitors (CGMs) may occur due to timing, hydration, temperature, and testing conditions.
  • Start with the meter turned off. Insert a clean test strip into the meter.
  • Wait for a beep and confirm that the flashing blood droplet icon appears on the screen.
  • Use the lancing device to obtain a small drop of blood.
  • Hold the meter at approximately a 45-degree angle (like a pencil) and gently bring the tip of the strip to the edge of the blood drop.
  • Allow the strip to "sip" the blood sample until the meter beeps and begins counting down.
Important tips:
  • Do not press the strip firmly into your finger. The strip needs airflow to properly draw the sample.
  • Do not bring your finger to the strip. Bring the strip to the blood drop.
  • Do not pull the strip away until the meter begins counting down.
For step-by-step instructions and a demonstration video, please visit our How to Test with the GK+ Meter Help Page.
Yes. Insert a strip, get a small drop of blood, and touch the strip to it — the meter does the rest. Setup takes minutes, and most users are testing confidently by their second try. The MyMojoHealth app walks you through pairing and tracks your readings automatically.
It is normal to see small differences between fingerstick meter readings, laboratory tests, and continuous glucose monitors (CGMs).

These methods measure glucose in different ways and at different times. Factors such as timing, hydration, temperature, circulation, and testing technique can also influence results.

When used as directed, the GK+ meter provides accurate and reliable readings within accepted regulatory standards.

If you have concerns about your results, our Customer Support team is happy to help.
Error messages typically indicate a simple issue such as:
  • Insufficient blood sample
  • Improper strip insertion
  • Using an expired or damaged test strip
Most errors can be resolved by checking the strip, ensuring proper insertion, and retesting with a fresh strip.

For a full list, see our Error Code Explanations Page.
Most customers do not need to use control solution during normal testing.

Control solution is typically used to verify that your meter and test strips are functioning properly, such as when opening a new package of strips or if results appear unusually inconsistent.

If you are testing as directed and your results seem typical for you, there is generally no need to perform control solution testing.

For detailed instructions, please visit our Control Solution Help Page.
The Keto-Mojo GK+ meter helps you monitor your ketone and glucose levels, whether you follow keto, low-carb, carnivore, fasting, or other metabolic approaches.

By measuring these biomarkers, it shows how your body responds to different foods and habits. This insight helps you make informed decisions about your routine and better understand what supports ketosis — and what may affect it.
The Keto-Mojo meter does not interact with medications, including GLP-1 therapies. It simply measures your blood glucose and ketone levels, giving you insight into how your body is responding to changes in diet, appetite, and metabolism.

As always, consult your healthcare provider when making changes to your routine.
Most low-cost meters only test glucose. The GK+ tests both glucose and ketones in one device. Beyond price, accuracy matters: the GK+ is FDA-cleared for at-home blood glucose self-monitoring, meets ISO 15197:2013 performance standards, connects to the MyMojoHealth app for trend tracking, and comes with a lifetime warranty.
The meter has a lifetime warranty — if it ever fails due to a manufacturing defect, we'll replace it. The only recurring cost is test strips and lancets.

App Support

MyMojoHealth is Keto-Mojo's official mobile app that connects to the GK+ meter via Bluetooth.

The app automatically syncs your glucose and ketone readings, allowing you to view trends, track results over time, and export data for personal records or care discussions.

MyMojoHealth is available for compatible iOS and Android devices. See full details on the app download page.
