What are the benefits of blood glucose monitoring?

People who regularly monitor their blood sugar levels can know about their conditions in a better way.

Knowing about your blood glucose levels will be important for you as you can decide what food you should take, what medications you should be on, your diet, exercises, and thus your doctor can help you with the condition.

By checking your blood sugar levels in a routine manner will help you keep track when the sugar level is low or high, and both of the symptoms can cause serious health problems.

Your doctor will advise you with medications based on your blood glucose levels, your age, type of diabetes that you have, your overall health, and various other factors.

It is very important to keep your glucose levels within the range for the best.

High blood sugar levels can end up causing long-term complications like heart disease, kidney failure, vision loss, damage to the nerves, and low blood glucose levels can lead to weakness, dizziness, sweating.

How does my glucometer works?

First, you need to use a lancet which pierces into the skin to take a small amount of blood for testing. Blood is sucked into the test strip.

The blood glucose reacts with an enzyme called glucose oxidase present on the test strip to form gluconic acid, which then reacts with ferricyanide to form ferrocyanide.

When the test strip is inserted into the meter, the electrode oxidizes the ferrocyanide, and this generates a current directly proportional to the glucose concentration.

Hence, the number displays on the device refer to the amount of glucose in the blood.

How to use a blood sugar monitor?

  • Before you test your sugar level, you need to wash your hands to get rid of germs and any kind of infection, dry your hands before taking the test.
  • Next, you have to put the testing strip in the device. Place the device on your finger, and it will prick into your skin and take a small amount of blood.
  • The blood goes on the strip that is inserted in the device. The monitor analyzes the blood and gives back a result, and it is displayed on the meter digitally in less than a minute.

It is important to follow the steps that come with the package and use it as instructed. Only that will give you accurate results.

If you are suffering from Type 1 diabetes, then you will have to test your blood glucose at least more than three times a day that is before and after your meals and exercises.

If you are suffering from Type 2 diabetes, then your doctor will inform you about the number of times you should check your blood glucose levels.

Buyer’s Guide

Every glucose monitor works in a very similar way, but there are few features and options that differ, which one needs to look at before buying to suit individual needs. First, talk to your doctor who can tell you about the glucose monitors and the requirements for yourself looking at your healthy lifestyle and budget.


It is important that you obtain accurate readings on your glucometer. There should be no interference of maltose and galactose in the blood sample. The meter should ensure fast and accurate results within the 5-seconds countdown. Also, check for automatic alerts that will notify you in case of fluctuations in the glucose level.

Storage space

Glucometers for home use should have a compact size and a light-weight design. The pocket-friendly design of the meter will allow you to carry it around with you conveniently. The kit should come with a plastic or waterproof pouch so that you can conveniently store your monitor, strips, lancing device and lancets.

Ease of use

Most glucometers come with easy steps and instructions that help you measure the blood glucose level conveniently. The monitor should have an easy to read LCD display and convenient controls.

A glucometer that requires a small blood sample of 0.5 µL is preferred as it is less painful and prevents frequent pricking. There should be no need for coding. Also, it should be easy to retrieve averages and analyze trends in results.

Battery life

Check the type of battery required by the glucose monitor before purchase. The batteries should be included with the glucometer kit. Also, it should have a long-lasting battery life so that you can use it for years to come.


Don’t just look at the retail price of the devices. The only thing that makes all the blood glucose monitors expensive is the test strips as one has to use a lot of them in just a single day.

The costs can increase from $18 to $265 at a minimum in a year for people who test four times a day. Replacement lancets are one more reason to add up to the expense.


If you have health insurance, it can cover a part of your supplies that are related to diabetes, and private insurances can help in covering some of the costs as well. So look out for certain brands and test strips that your insurance might cover for. Find out how may test strips can be covered for you in a month. The coverage also will depend on whether you use insulin or not.

Automatic Coding

The blood glucose meters need to be calibrated to a set of test strips, and there are some which require you to download an application or enter a particular code that will scan the code with the smartphone.

Make sure you put the correct details as otherwise, you will get inaccurate results. Few models also use a removable code chip that can calibrate the meter to each batch strips.

Data Storage

The common number of test results that a convenient glucose meter can store is around 360 tests. Some of the devices also track your average readings over a span of 7, 14, or 30 days to give you an overview of the blood sugar levels. If you need to test more frequently, then go for a blood glucose monitor that has more memory.

Test Time

Look for models that take around 5 seconds or less to calculate the results. The difference in the seconds won’t seem like much, but when it comes down to taking the test at least 3 to 5 times a day, it can be irritating to wait for long.

Markers and Flags

Markers and Flags are features that will allow you to take note of whether the blood sugar level was calculated before or after a meal or exercise.

Blood-Sample Size

Today we need a small sample of blood for testing, unlike old times, which makes this process less painful. If you are sensitive to lancing, then you should look for devices that require less than one ml of your blood for testing blood sugar levels.

Unit Size

If you want a device that you can take along with you on the go, then look for a compact device. There are models that are pretty huge and can store multiple strips for you so that you don’t have to load each strip for every test, but that can be a bit bulky.

These devices are convenient to use at home though especially for people who have vision difficulties. Most of the devices require a medical battery so you can refer to look for devices that use AAA batteries; this makes it easier to replace.

Frequently Asked Questions

1. What are the different types of glucometer?

The different types of glucometers are:

Continuous Glucose Monitors (CGM): These glucometers do not require test strips. Instead, it measures the glucose level with the help of a sensor implanted under the abdominal skin. CGMs can take readings all day and night. However, you need to ensure that it is calibrated properly.

Self-Monitoring Glucose Meters (SMBG): These are the standard glucose monitoring systems that are portable, cheap, and easy to use. SMBG measures the glucose level by taking a small sample of blood on test strips. It ensures quick and accurate results.

Non-Invasive Glucose Meters: These models are not readily available in the market. They do not require blood samples. Hence, there is no finger pricking involved. Low-power radio waves are passed through the blood enriched areas of the body to measure the glucose level.

2. What is the best brand of glucometer?

The best glucometer brands are as follows:

  • Accu Chek
  • Dr. Morepen
  • Bayer Contour
  • One-Touch


It is advised to choose what suits your requirements. Keep in mind about the price, accuracy, your insurance, and then think about which blood glucose monitor is best for you. Make sure you are aware of the expiration dates of the test strips used for the blood samples.
