Blood Glucose Check - Howrah

Overview[edit | edit source]

A glucose meter is a small, portable machine that's used to check how much glucose (a type of sugar) is in the blood (also known as the blood glucose level). People with diabetes often use a blood glucose meter to help them manage their condition.

How it works[edit | edit source]

Design of the flexible epidermal biomicrofluidic device for continuous blood glucose monitoring

Glucose meters work by analyzing a small amount of blood, usually from a fingertip. The user pricks their finger with a small, sharp needle called a lancet, places a drop of blood on a test strip, and then inserts the strip into the meter. The meter then displays the current blood glucose level.

Types of Glucose Meters[edit | edit source]

There are several types of glucose meters available, including:

  • Traditional glucose meters: These require a small drop of blood to measure glucose levels.
  • Continuous glucose monitors (CGMs): These use a sensor inserted under the skin that measures glucose levels in tissue fluid.
  • Non-invasive glucose meters: These are a newer type of meter that do not require a blood sample. They work by shining a light through the skin and measuring the amount of light that is absorbed by the glucose in the blood.

Accuracy[edit | edit source]

The accuracy of glucose meters is a critical factor for people with diabetes, as they rely on these readings to manage their condition. Most glucose meters are accurate within 10-20% of laboratory values, which is sufficient for the purposes of managing diabetes.
