There are two ways to test your body for ketones.
Urine Ketones: Examples: Ketostixs® or Chemstrips®
Urine is applied to reagent strip and the color change shows the level of ketones.
- Easy to use
- Reasonably priced
- Results are not current; they may lag by as many as three hours
- Color changes are categorized as trace, small, medium, and large only
- Dehydration can affect results
CAUTION: Be sure to get individually foil wrapped urine ketone test strips! Test strips rapidly loose their accuracy once they are exposed to the air. By using individually foil wrapped strips, only the strip you are using is exposed to the atmosphere.
Blood Ketones: Example: Abbott Precision Xtra®
Quantitative ketone (beta-hydroxybutyrate) is measured. The normal level is less than 0.6 mmol/l. Check the manufacturer’s package insert for an explanation of results and more information. CardioChek, BioScanner 2000, and other blood ketone testing devices are also available.
- Results are more accurate and reflect ketone levels at the time the test is done vs. lag time found with the urine testing
- The blood ketone test strips are expensive
- May not be covered by medical insurance
- Test requires a meter
