=Measuring Acetone=
Acetone can be measured in the breath, but the devices are currently at an experimental stage and it's not clear what the cost would be. This approach would overcome many of the problems seen with urine AcAc measurement. However, there would still be some delay between changes in the AcAc level and the levels of Acetone, as well as differing levels of AcAc and BOHB.
=My Results=
I measured my blood BOHB, urine AcAc (using ([[KetoAnalysis]]), and my blood glucose. The charts below show the relationship between the values, with the regression line in blue and the 95% confidence intervals shaded. As you can see, for my readings there is better correlation between blood glucose and blood BOHB than there is to urine AcAc. I tried adjusting for hydration using the Urine Specific Gravity values from the test strips, but this made little difference to the correlation. Multiple regression of blood glucose and urine AcAc to blood BOHB did improve the model to r<sup>2</sup>=0.73.
