Breath ketone analyzers with mouthpieces

When it comes to breath ketone analyzers with mouthpieces, there are a few options to consider. Most of these devices come with multiple mouthpieces, so you don't have to worry about replacing them right away. Here are some detailed descriptions of some of the best options:

Biosense Ketone Breath Meter

The Biosense Ketone Breath Meter is a clinically-validated, medical-grade device developed in the USA by Readout Health. It offers accurate and reproducible results by analyzing the end of your exhale, which it collects via vents on each side of the mouthpiece. This "deep lung sampling" technology ensures that the device only analyzes the part of your breath that comes from deep down in your lungs. It also has a microphone that detects changes in the sound you make as you exhale, so it knows when you've reached the end of your breath.

The Biosense meter measures acetone in your breath and correlates it with blood ketone levels (BHB). It has a rechargeable battery that lasts a couple of days, and it comes with two extra mouthpieces made from medical-grade nylon. The device is easy to use and can be shared with family members, although their results will show up on your app. It is also compatible with apps like Apple Health and Google Fit. The main downside is the cost—$299—although you can test your ketone levels an unlimited number of times without buying test strips or recalibrating the device.

These are just a few examples of breath ketone analyzers with mouthpieces. Each has its own advantages and disadvantages, so it's important to consider your specific needs and preferences when choosing the best device for you.

Accuracy and consistency of readings

To evaluate the accuracy of keto breath analysers, it is essential to compare their readings with a commercial blood test for beta-hydroxybutyrate, the ketone that the body produces when in ketosis. This can be done by drawing blood after a fast and then using a ketone meter for a finger-prick test within a few minutes. By repeating this procedure several times and testing during different stages of ketosis (full-blown, moderate, and out of ketosis), we can assess the overall accuracy and consistency of the meter.

In a study conducted by LifeOmic, Biosense was found to be the most reliable device for measuring breath ketones. The measurements from Biosense showed an increase in breath ketones that matched the pattern observed with blood ketone devices, although not as closely. Keyto's measurements also loosely matched the progressive increase in ketones observed in blood devices, while KETONIX did not detect the expected increase in ketones, indicating that it may not reflect ketosis accurately.

When it comes to consistency, it is important to evaluate whether the meter provides identical or very similar readings for samples that are likely the same. In the LifeOmic study, both Precision Xtra and Keto-Mojo showed a wider difference between readings during the first test when ketone levels were high. However, during the second test, these meters produced identical readings, indicating that the first test may have been an aberration or that the margin of error increases with higher ketone levels.

It is worth noting that no single reading should be considered entirely trustworthy, and it is recommended to use a combination of breath and blood ketone meters for a more accurate picture of your metabolic state. Additionally, factors such as environmental conditions, hydration levels, and blood iron status can also affect the variability of measurements.

Overall, while some keto breath analysers may provide more accurate and consistent readings than others, it is essential to consider that no device is perfect, and using multiple approaches can help ensure a more comprehensive understanding of your ketone levels.
