What is the working principle of glucometer?

When blood or a glucose solution is placed in the strip, a chemical reaction occurs inside it, generating a small electrical current proportional to the glucose concentration. This current is constantly monitored while the strip is in place, allowing the device to monitor when blood is placed.

What electrochemical method is used in a glucose measurement?

The hexokinase assay is the reference method for measuring glucose using spectrophotometry in many clinical laboratories [32]. Glucose biosensors for SMBG are usually based on the two enzyme families, GOx and GDH. These enzymes differ in redox potentials, cofactors, turnover rate and selectivity for glucose [33].

What is a glucose meter and How Does It Work?

A continuous glucose monitor (CGM) uses a filament coated in glucose sensing enzymes to detect glucose in the interstitial fluid (the fluid between your cells). As a wearable sensor, a CGM automatically detects and measures glucose levels 24 hours a day.

Which sensor is used in glucometer?

The glucose sensor is an amperometric glucose sensor based on the detection of oxygen. The oxygen sensor incorporates dual-enzyme electrode technology with both enzymes, glucose oxidase and catalase, immobilized in a cross-linked protein gel.

What is the other name of glucometer?

A glucose meter, also referred to as a “glucometer”, is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart.

What does glucometer measure?

A small device called a glucose meter or glucometer measures how much sugar is in the blood sample. The drop of blood you get with a finger prick is often enough to use on a test strip. A finger prick can be done with a special needle (lancet) or with a spring-loaded device that quickly pricks the fingertip.

How does Accu Chek work?

The Accu-Chek Active blood glucose meter can help to make it convenient by giving you fast, hassle-free, and accurate results in 4 simple steps. Prick your finger with the lancet to draw out a blood drop. Carefully touch the blood drop onto the green field of the test strip. Read the blood glucose result.

What is code key in Accu-Chek?

Accu-Chek Aviva Expert and Accu-Chek Aviva Combo meters These meters come precoded with a black code key that remains in place for the life of the meter. There’s no need to manually code the meter. If you do not have a black code key, please contact Accu-Chek Customer Care.

What is the accuracy of glucometer?

For determining accuracy, the sensitivity of Beurer glucometer was 96%, higher than Bionime (82%) and Accu-chek (81%)….[Table/Fig-2]:

Why does my glucometer give different readings?

Test strips that have expired or have been exposed to extreme heat or cold can provide inaccurate readings. If you use one of these and then move to a new box, you could get very different numbers. Also, make sure you are using the correct test strip.

What is the working principle of a glucometer?

1 Working principle of a glucometer: 2 i. A glucometer determines the concentration of glucose in the solution. 3 Glucometer test strips: i) In each glucometer test strip which are to be used for determining glucose in the blood, contains an enzyme called glucose oxidase.

What is the principle of operation of a glucose meter?

The principle of operation of the meter The basic principle of the meter is to determine the number of “sugar” in the blood. There are two variations of this action. The first option is photometric determination, and the second type Electromechanical. Modern blood glucose meters allow you to show the exact sugar content of a person.

How are glucometers used to diagnose diabetes?

A glucometer is a device that is designed to measure the level of glucose in the blood. It is also used for the diagnosis of carbohydrate metabolism in people who suffer from diabetes mellitus. Thanks to him, the level of glucose in the blood is determined on the basis of the data obtained.

How does photometric and electromechanical blood glucose work?

One of them is called photometric, the second – electromechanical. So, the first option works as follows. In the interaction of blood glucose and a special reagent that will be applied to the test strip, the latter stains blue. So the intensity of the shade depends on the concentration of glucose.
