Ha — if only it were just being friendly! When a glucose meter displays "HI," it actually means your blood sugar is too high to measure — typically above 600 mg/dL. This is a serious reading that needs attention right away.

Here's what to do:

- Don't panic, but act quickly — contact your doctor or seek medical help immediately
- Stay hydrated — drink water if you're able to
- Check for ketones if you have a ketone testing kit
- Do not exercise, as this can sometimes raise blood sugar further in this situation There are also a few things that can cause a falsely high reading, such as:

- Sugar or food residue on your fingers
- Expired or improperly stored test strips
- A low meter battery
- Extreme temperatures affecting your meter or strips

Try washing and drying your hands thoroughly, then retest. If the "HI" reading appears again, treat it as a real high and seek medical guidance immediately. Don't wait on this one!
