Ketosis Accuracy
Sources:
The accuracy of ketosis measurement varies depending on the method used and the context. Here are insights from different experts on this topic:
Measurement Methods
-
Urine Strips:
- Initial Usefulness: Urine strips measure acetoacetate and are useful for beginners to confirm ketosis. However, as individuals become more fat-adapted, these strips become less accurate because the body gets better at using ketones, resulting in fewer ketones being excreted in urine 1 2.
- Quantitative Devices: Use of devices like the Clinitex status device combined with Siemens Xg multistick can offer more quantified results, but even these have limitations influenced by factors such as hydration status 3.
-
Blood Tests:
- Precision: Blood tests like those done with the Precision Extra and Keto Mojo measure beta-hydroxybutyrate (BHB). These provide more accurate and precise readings compared to urine strips and are considered reliable methods for tracking ketosis 2 4.
- Accuracy Concerns: Instances of inconsistencies in readings, like those experienced by users of Keto Mojo, highlight how variations in blood glucose readings can occur due to factors like strip quality and user technique, although they often still meet FDA and ISO accuracy standards 5.
Expert Perspectives
- Dom D’Agostino emphasizes the varying accuracy of urine ketone strips and acknowledges their utility with correct application. Blood measurements, particularly using devices like the Abbott Labs Precision Extra, are considered to offer better reliability 2 3.
- Dorian Greenow and Dave Asprey discuss the broader implications of accurate ketosis measurement, noting the potential for inaccuracies leading to significant issues, such as legal implications in DUI cases. They stress the importance of using well-correlated devices like the Keto Mojo for reliable data 6.
- Mike Mutzel and Joanna Wilcox also note that as one becomes more fat-adapted, urine tests become less useful, suggesting that other methods might be more beneficial for continuous tracking 1.
Overall, while urine strips can be a good initial indicator, blood tests are generally preferred for ongoing and accurate ketosis tracking.
