What can interfere with my glucose or ketone measurements?
- Here are some of the most common factors that can affect your blood glucose and ketone measurements
- Strip placement in the meter port and blood fill level. Make sure your strip is firmly placed into the port, and that the blood sample completely fills the channel
- Hydration! If you are dehydrated or anemic, your results may be less accurate
- Hygiene and testing protocol. Use the provided alcohol swabs before every test (or wash your hands) and make sure to code sync each new vial of ketone strips
- Altitude, temperature,and humidity. Store test strips between 36-86°F. Store at 10-90% humidity. Avoid heat and direct sunlight. Use the test strips at temperatures between 45.5-113°F
- Interfering substances. Some substances, such as Tylenol, elevated uric acid, or low glutathione may interfere with your glucose test results
- Food or contaminants like lotions, exogenous ketones, and MCT oil on the skin or strips (i.e. if strips come into contact with a surface that has a contaminant)
- Exposure to air. Studies have shown that extended exposure of the blood sample to air can result in readings with a 10% variance, as a result of evaporation, coagulation, and changes in a small volume of blood
- Strip expiration. Use your strips within 6 months of opening the vial
