In the event of an error while checking your blood glucose, an error message will appear on your meter screen.
| Error Message | How to Troubleshoot |
|---|---|
| Blood Applied Too Quickly | Blood was applied too quickly after the strip was inserted and before the meter was ready. After inserting the strip, please wait until you see the message “Ready to Check Glucose” to apply blood. |
| Contaminated or Used Strip | The strip that you are using is either contaminated or has been used. Please use a new strip and try again. |
| Insufficient Blood Sample | Sometimes the blood sample might be too small to be measured with accuracy. Please remove the strip and try again using a new strip. |
| Glucose Strip Coding Error | Please insert a new test strip from the same vial and try again. If the error persists, contact Member Support. |
| Temperature too High | The outside temperature is above 113°F, which is too high to give an accurate reading. |
| Temperature too Low | The outside temperature is below 41°F, which is too low to give an accurate reading. |
| Test Strip Removed | If the strip is removed before a reading can be obtained, you’ll receive this error message. Please fully remove the strip and try again with a new strip. |
| Hematocrit Error | Your hematocrit level is below 20% or above 70%. The Livongo meter operates in the hematocrit range of 20% to 70%. Very high (above 70%) and very low (below 20%) hematocrit levels can cause false results. Talk to your doctor to learn more about your hematocrit level. |
| Glucose High: > 600 mg/dL | The Livongo meter can measure blood glucose accurately from 20 mg/dL to 600 mg/dL. If your blood glucose is higher than 600 mg/dL, the screen will display this message. Please call your Doctor if you receive this message. |
| Glucose Low: < 20 mg/dL | Livongo meter can measure blood glucose accurately from 20mg/dL to 600 mg/dL. If the blood glucose is lower than 20 mg/dL the screen will display this message. Please call your Doctor if you receive this message. |
