What is the reading range when the machine says HI?
The meter is designed to provide a numerical value for blood glucose in the range of 20–600 mg/dL or 1.1-33.3mmol/L. Results higher than this range will display a "HI" value.
If your blood glucose result does not match how you feel, follow these steps: 1. Perform a control test. See Chapter 2, Control Tests.
2. Repeat the blood glucose test. See Chapter 4, Performing a Blood Glucose Test with Blood from Your Fingertip.
If your blood glucose result still does not match how you feel, follow your healthcare professional’s instructions or call your healthcare professional immediately.
