What do “Lo” and “Hi” ketone meter readings mean?
- Last updated November 19, 2017
For Keto-Mojo models GK+ and GKI
These meters read ketones from 0.1 mmol/L ~ 8.0mmol/L.
Lo Readings
Keto-Mojo meters accurately read ketones down to 0.1 mmol/L.
Following are possible reasons you may get a Lo reading:
- You are not in nutritional ketosis and need to reevaluate your carbohydrate consumption and fat intake. Then, test again in a day.
- Wash and dry your hands, then repeat the test using a new test strip.
- Your blood sample size is too small. Learn more here.
- Re-test using this testing protocol.
Hi Readings
Readings above 8.0 mmol/L will show “HI,” meaning your ketone levels are above our ability to measure them.
Following are possible reasons you may get a HI reading:
- You are in Therapeutic ketosis. A therapeutic ketogenic diet can be helpful for a range of chronic health conditions such as cancer, epilepsy, Alzheimer’s disease or dementia.
- Wash and dry your hands, then repeat the test using a new test strip. If your result still flashes HI, contact your health care professional as soon as possible.
