Checking Blood Sugar

Explore the various methods for checking your blood-sugar levels and maintaining good control.

People with type 1 diabetes (T1D) must check their blood-glucose levels often and are usually advised to do so 4‒6 times a day.

There are two ways in which people can track their blood-sugar levels:

Glucometer (glucose meter)

  • Checking blood-glucose levels involves taking a small drop of blood, usually from the fingertip, and placing it on a test strip in a glucometer, or glucose meter.
  • Blood-sugar levels are measured in milligrams per deciliter (mg/dL). A normal blood-sugar level is between 70 and 140 mg/dL, but depending on the person and a doctor’s recommendation, sometimes the recommended target range is expanded.

Continuous glucose monitor (CGM)

  • A continuous glucose monitor is a device that tracks a person’s tissue sugar in real time.
  • CGMs work by wearing a sensor just under the skin that measures the tissue-glucose levels. The levels are then relayed to a receiver, which displays the readings in real time.

Technology

T1D tech is getting smarter all the time, helping you manage the disease more easily and with better control.
