what is a glucometer?

A “glucometer” is a clinical gadget for deciding the rough estimation of glucose in the blood.

It is a very handy and great friend for a diabetic patient.

It has become a vital and most useful medical device for Home Blood Glucose Monitoring or also called HMGM.

 A little drop of blood, acquired by pricking the skin with a lancet, is set on a dispensable test strip that the meter peruses and uses to ascertain the blood glucose level. The meter then, at that point shows the level in units of mg/dL or mmol/L. 

It is widely used nowadays all over the world by both type1 and type 2 diabetics

Leland Clark introduced his first paper about the oxygen terminal, later named the Clark anode, on 15 April 1956, at a gathering of the American Society for Artificial Organs during the yearly gatherings of the Federated Societies for Experimental Biology. In 1962, Clark and Ann Lyons from the Cincinnati Children’s Hospital fostered the principal glucose protein cathode. This biosensor depended on a dainty layer of glucose oxidase (GOx) on an oxygen cathode. Hence, the readout was the measure of oxygen devoured by GOx during the enzymatic response with the substrate glucose. 

Another early glucose meter was the Ames Reflectance Meter by Anton H. Clemens. It was utilized in American clinics during the 1970s. A moving needle showed the blood glucose after about a moment. 

Home glucose checking was shown to improve glycemic control of type 1 diabetes in the last part of the 1970s, and the main meters were advertised for home use around 1981.

 The two models at first predominant in North America during the 1980s were the Glucometer, presented in November 1981 whose brand name is possessed by Bayer, and the Accu-Chek meter (by Roche).

Test strips that changed color and could be read visually, without a meter, have been widely used since the 1980s.

What are the different types of glucometers?

Hospital  glucose meters 

Exceptional glucose meters for multi-patient emergency clinic use are currently utilized. These give more intricate quality control records. Their information taking care of capacities are intended to move glucose results into electronic clinical records and the research facility PC frameworks for charging purposes. 

Blood testing with glucometers utilizing test strips 

Size of a glucometer

 The normal size is currently around the size of the palm of the hand, in spite of the fact that emergency clinic meters can be the size of a controller. They are battery-fueled. 

Test strips

 A consumable component containing synthetic substances that respond with glucose in the drop of blood is utilized for every estimation. For certain models, this component is a plastic test strip with a little spot impregnated with glucose oxidase and different segments. Each strip is utilized once and afterward disposed of. Rather than strips, a few models use circles, drums, or cartridges that contain the consumable material for different tests. 


Since test strips may shift from one cluster to another, a few models require the client to physically enter a code found on the vial of test strips or on a chip that accompanies the test strip. By entering the coding or chip into the glucose meter, the meter will be adjusted to that clump of test strips. Be that as it may if this interaction is completed erroneously, the meter perusing can be up to 4 mmol/L (72 mg/dL) off base. The ramifications of a mistakenly coded meter can be not kidding for patients effectively dealing with their diabetes. This may put patients at an expanded danger of hypoglycemia. Then again, some test strips contain the code data in the strip; others have a central processor in the vial of strips that can be embedded into the meter. These last two techniques lessen the chance of client blunder. One-Touch has normalized their test strips around a solitary code number, so that, when set, there is no compelling reason to additional change the code in their more seasoned meters, and in a portion of their fresher meters, it is absolutely impossible to change the code. 

 How much volume of blood needed?

The size of the drop of blood required by various models changes from 0.3 to 1 μl. (More seasoned models required bigger blood tests, normally characterized as a “hanging drop” from the fingertip.) Smaller volume prerequisites diminish the recurrence of inefficient pricks. 

Testing time of a glucometer

 The occasions it takes to peruse a test strip may go from 3 to 60 seconds for various models. 


The glucose esteem in mg/dl or mmol/l is shown on an advanced showcase. 

 Blood Glucose versus plasma glucose: 

Glucose levels in plasma (one of the segments of blood) are higher than glucose estimations in entire blood; 

 Does a glucometer have memory?

 Most meters presently incorporate a clock that is set by the client for date and time and a memory for past test results. Memory is a significant part of diabetes care, as it empowers the individual with diabetes to track the executives and search for patterns and examples in blood glucose levels over days and weeks. Most memory chips can show a normal of late glucose readings. 

Bottom lines

Glucometer is a very handy and popular medical device used to estimate blood glucose.
But as it a digital product so many times it may show errors.
Hence it is very much important not to depend on it blindly.
