Glucose meter

Glucose meter is a medical device used to determine the concentration of glucose in the blood. It is often used by people with diabetes to monitor their blood sugar levels.

Blood Glucose Check - Howrah

Overview

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

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

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

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.
