Frequently Asked Questions

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

Getting Started

The GKI meter is designed for customers across Europe, both EU and non-EU countries (e.g., Switzerland, Norway).

The GK+ meter is designed for customers in North and South America.

Both meters measure both blood glucose and blood ketones.

Please note that GKI test strips and GK+ test strips are not interchangeable.

GKI (Glucose Ketone Index) is a calculated ratio based on your glucose and ketone readings, and can be displayed via the free MyMojoHealth app.
The Keto-Mojo GKI meter is CE-marked for blood glucose and ketone monitoring, ideal for individuals in Europe who want actionable insight into their metabolic data.

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 data into education or research programs
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 GKI meter
  • Compatible glucose and/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.
They are sold separately and are not interchangeable.
Only Keto-Mojo GKI glucose test strips and GKI ketone test strips are compatible with the GKI meter.
Test strips from other brands or manufacturers are not compatible.
Many users test 1–3 times per day.
Test strips are sold in packages of 50 or 60 depending on the type, so consider how long one box will last based on your testing frequency.
Keep the packaging sealed until use, and avoid exposure to heat, moisture, or direct sunlight. Do not refrigerate or freeze test strips.
Improper storage may affect accuracy.
The meter itself does not expire. However, test strips, control solution, and lancets have expiration dates printed on their packaging. Always check before use.
Glucose measurement units vary by country in Europe.
For a full list of units by country, please see our Glucose Measurement Variants by Country help page.

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.
The Keto-Mojo GKI meter meets ISO 15197:2013 performance standards for blood glucose testing. In performance testing, 95% of glucose readings fall within ±15% of laboratory reference values.

As with all finger-stick meters, small differences compared to lab tests or CGMs may occur due to timing, hydration, temperature, and testing conditions.
Yes! Insert a strip, get a small drop of blood, and touch the strip to it at a 45 degree angle — 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. For more details, check out our how-to videos.
Yes! Blood ketone testing is the most accurate way to confirm nutritional ketosis — more reliable than urine strips or breath meters. The GKI meter measures your blood ketone level directly.
The GKI meter is CE-marked and used by individuals managing Type 1, Type 2, and pre-diabetes, as well as those on GLP-1 medications. It does not interact with medications. Always work with your healthcare provider to determine how best to use your results.
Most meters only test glucose, the GKI tests both glucose and ketones in one device. It meets ISO 15197:2013 standards, connects to the free 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.
Error messages typically indicate a simple issue such as insufficient blood sample, improper strip insertion, or an expired strip. Most errors are resolved by retesting with a fresh strip. See our Error Code Explanations for a full list.
