Rated 4.2/5 stars on Amazon, they are pricier but user-friendly, with the app providing insights into various health aspects. However, some users doubt the analysis’s accuracy, and it’s important to remember these strips don’t replace standard lab tests.

Other Commendable Ketone Test Strips

However, users have noted that these strips might not be as reliable as others, like the Bayer Keto Diastix Test Strips, and some may be faulty. So, while they’re good value, it’s wise to interpret the results cautiously.

Keto-Mojo Ketone Tests

Keto Mojo Monitor
Keto-Mojo Ketone and Blood Glucose Monitoring System

Keto-Mojo is one of the most popular brands known for its blood glucose and blood ketone testing devices and strips. Many of their US users highly regard the Keto-Mojo blood meter as one of the most accurate in the market. However, they are difficult to find and purchase in Australia (they’re not even sold on Amazon Australia).


Lumen monitoring device

Lumen is a versatile device that tracks more than just ketosis, making it suitable for anyone on a keto diet. It monitors progress and metabolism over time. It’s also appealing for those seeking a varied diet, as keto can be limiting.

The device works by measuring CO2 levels in your breath to determine your body’s main fuel source, carbs or fat. You breathe into Lumen, and based on the readings, it provides a tailored diet plan, plus daily tips on nutrition, sleep, and exercise through its app.

User reviews are mixed, with some losing weight successfully, while others question its effectiveness and the science behind it.

Choosing A Ketone Testing Device

There are currently three main ways to test your level of ketones. We’ll compare these three methods, breath, blood, and urine, to help you gauge which method might suit your wallet, preference, and lifestyle best.

Blood Ketone Meters

  • Accurate and reliable
  • Quick results
  • Suitable for beginner and experienced keto dieters
  • Many come with apps to store data and track progress
  • Results are less likely skewed by environmental factors
  • Expensive (you’ll need to purchase a lancing device, lancets, and blood ketone test strips
  • Finger pricks to draw blood sample

Blood ketone meters are considered the most accurate for testing ketones at home, particularly measuring beta-hydroxybutyrate (BHB) produced during low-carb, high-fat diets. While more precise than urine strips, they’re pricier due to ongoing costs for compatible test strips and lancets, plus the initial purchase of the monitor and lancing device. If accuracy is a priority and you’re okay with the investment, a blood ketone meter is an excellent choice.

Breath Ketone Meters

  • Suitable for those who do not wish to prick their fingers
  • Does not require strips, a lancing device, or lancets
  • Painless and non-invasive
  • Results can be skewed by environmental factors and device technique
  • Device calibration and sensor replacement required
  • Devices can be quite expensive

Breath ketone meters measure acetone, a byproduct of fat breakdown, to indicate ketosis levels. They’re generally reliable, but factors like diet, smoking, alcohol, exercise, and even mouthwash can affect accuracy. While they don’t need test strips or lancets, making them potentially more cost-effective, it’s important to use them correctly and be aware of maintenance like calibration. Do your research before buying, as cheaper models might not be very accurate.

Urine Ketone Strips

  • Cheaper option
  • Easy to use and non-invasive
  • Fast results
  • Not very accurate
  • Results can be impacted by your hydration levels
  • Not suitable for those on a long-term keto diet
  • Sensitive to humidity and air (destabilises over time after opening)

Urine ketone strips are affordable and easy to use, mainly for detecting diabetic ketoacidosis in people with diabetes. They’re also popular among keto diet followers to check for nutritional ketosis. To use them, you either urinate directly on the strip or dip it in a urine sample, with the colour change indicating ketone levels. However, they’re not as accurate as blood ketone monitors, especially over time, as the body adapts to the keto diet and excretes fewer ketones in urine.

Signs You’re in Ketosis Without Testing

  • Increased Thirst and Urination: As your body enters ketosis, it sheds excess water, leading to increased thirst and more frequent urination.
  • Keto Breath: A telltale sign of ketosis is a distinct breath odor, often described as fruity or similar to nail polish remover.
  • Reduced Appetite: Many people in ketosis experience a decrease in hunger. This is partly due to the appetite-suppressing effects of the diet and the ketones themselves.
  • Short-Term Fatigue: Initially, as your body transitions to burning fat instead of carbs, you might feel tired or fatigued. This is often temporary.
  • Increased Energy and Focus: After the initial fatigue phase, many report higher energy levels and sharper mental focus.
  • Weight Loss: Rapid weight loss in the first week or two is common, mainly due to water loss.
  • Digestive Changes: Some people experience changes in their digestive system, such as constipation or diarrhea, when they first start a keto diet.
  • Insomnia or Changes in Sleep Patterns: Initially, some people on a keto diet may experience difficulty sleeping or changes in their sleep patterns.

Remember, these signs can vary from person to person, and not everyone will experience all of them. Additionally, some of these symptoms can be associated with other conditions, so they’re not definitive proof of being in ketosis.

Updates made: 1. Replaced Ketonix Basic (no longer available) with Ketonix Green Basic. The Ketonix Green Basic can connect via Bluetooth, WiFi, and USB, has a shorter startup time, and has a permanent USB cable attached. 2. Replaced Coolker Ketone Breath Analyzer (not available currently) with Ortorex Ketone Breath Meter. The Ortorex Ketone Breath Meter is affordable, compact, portable, and user-friendly.
