Answer:
A ketogenic diet or diabetes can produce compounds that may affect some breath-testing situations, so the result should be reviewed alongside the device, procedures, and medical evidence.
A ketogenic diet and diabetes can cause the body to produce ketones and related compounds. In some circumstances, those compounds may interfere with breath testing or contribute to a misleading result.
Whether this is a viable defense depends on the testing instrument, its safeguards, the procedures used, and the person’s medical or dietary history. The breath result should be evaluated with all available records rather than viewed in isolation.
If ketosis or diabetes may have affected your test, share that information with an experienced Denver DUI attorney. A lawyer can determine whether expert review or additional evidence may support the defense.
