Today, a lot of people suffer from lifestyle diseases and diabetes is one of them. The good part is that diabetes can be managed easily with the help of insulin and other lifestyle changes. One thing that can help you in managing the lifestyle disease is a glucometer which basically helps you in measuring the quantity of sugar in your blood. This can be done at home so that you do not have to spend hundreds of rupees in getting the test done.

High sugar levels can lead to kidney failures, blindness, nerve damage and other complications like seizures. All this can be prevented by monitoring your sugar levels if you suffer from diabetes. In such a case, it becomes really important to have a glucometer with yourself to monitor diabetes and to change the lifestyle accordingly.

So, if you have a glucometer, all you have to do is that you have to use a new needle to pinch your finger, extract a drop of blood and put it on the glucometer strip. You then insert the strip in the glucometer and there you have the reading of your sugar levels.

Depending on your sugar level, you can alter the dose of your medicine. The glucometer can surely help in saving a lot of lives this way and it is a must-have item at home if you suffer from diabetes or if anyone else in your family suffers from diabetes.

In this article, we are going to share al possible information regarding Glucometer which includes the Working of the Glucometer, Best Glucometers Available in India, Buying Guide and the Sugar Chart Levels along with a Basic User Guide.

So, let us now start by looking at how does blood glucose meter works.

How Do Blood Glucose Meters Work?

Most of us have used a glucose meter at some point in time but do you really know how does this glucose meter works? What really happens after you put the blood on the glucometer strip and what happens when you insert it in the machine? Well, we have explained the working of the blood glucose meter in this section so check out the working principle behind the blood glucose meter.

  • It all starts with you extracting blood from the capillary. Once you extract the blood and put it on the strip, a reaction begins instantaneously. The blood reacts with the enzyme, glucose oxidase.
  • The reaction now enables the blood to interfere with the electrode which is present in the meter. This way, the flux of the reaction generates an electrical signal in the machines.
  • Now, the glucometer is actually calibrated to measure the flux and get you the reading. The chip inside the glucometer is calibrated to provide you with a reading by measuring the change in current and the strength of the current.
  • The higher the amount of glucose in the blood accounts of higher the flux and higher current. This means that the higher current gives you a higher reading while you are measuring the blood glucose levels.

This is the basic working principle behind the glucose meter. Let us now look at the top 9 glucometers available in India in 2024.

With 25 test strips and a genuine price, Alere G1 Glucometer nails the spot in our list for being an adequate choice.

There are only three buttons to use this machine. Due to the low price, it is a genuine deal, but if you consider all reviews, most of them will be saying trash about the design.

How to Choose a Blood Sugar Testing Machine (Glucometer)?

Best Glucometer Buying Guide
There are certain factors that you need to consider while you plan to buy a glucometer or blood sugar testing machine. In this section, we have covered all such factors so that you can find the best machine for yourself which will meet all your needs. Let us now have a look at these details.

1. Pre Meal and Post Meal

The sugar reading before and after the meal can vary largely and in such a case, it really makes a lot of sense to buy a glucometer that can tag the reading and measure it accordingly. This is certainly one of the most desired features in a glucometer.

2. Portability

You need to understand the fact that you will have to travel with your glucometer in order to manage diabetes. This means that the glucometer should be really portable and a carry case should be included as a part of standard equipment. This would ensure that you are able to measure your sugar levels on the go. You can even opt for the machines that can be connected to smartphones to give you the reading.

3. Cost

This is another factor that you need to consider while you are purchasing the glucometer. For once, you can ignore the cost of the machine because that is a one-time investment but you need to account for the cost of test strips because that would be a recurring expense for you. Buy the glucometer which has affordable and cheap glucometer test strips.

4. Coding

The next thing to consider is the coding mode. Whenever you buy a new pack of the Glucometer test strips, you will have to code the details into the machine so that it auto-calibrates itself. To avoid all this hassle, you can opt for a machine that comes with an auto-coding facility for you.

5. Memory Function

The next thing to consider while buying a glucometer is the memory function. Purchase the glucometer which has memory function as that can help you in analyzing the trend. You can even opt for a machine that transfers the data to your computer as this would help you in getting a long term analysis point.

6. Test Time

The test time of the machine should be low. Long test time may induce errors and this is certainly not a favorable condition to be in. Check of the test time and ideally, most of the machines have a test time of 5 seconds which is acceptable criteria.

7. Notification

You can also buy a machine that notifies you in case of high, low or very high sugar levels. This is a great feature for the elderly as they would not have to remember the ideal reading for themselves. They would not have to open the chart again and again either.

Checking for the notifications is much easier to ensure that this is a must-have feature. Some of the machines may have a beeper while others may also have an LED notification.

8. Other Features

You can also check for other features that are a part of the machine. For example, some glucometer has a feature to auto-eject the test strip so that you do not have to touch them while another feature that is found in the glucometer is the notification alert for the presence of ketones. It is again another feature that most of the people prefer having in their machines.

9. Warranty

Check for the warranty that comes with the machine as the company will replace your machine in case of any issue if it is covered under warranty. Usually, companies offer a lifetime warranty in India for the glucometer but there are some reliable brands that offer a warranty of 1 year or 5 years. You can consider them both but do not purchase the ones which are not covered under warranty.

10. Insurance Cover

Lastly, some of the insurance covers offer your reimbursements for the money that is spent on the machine and test strips.

Check if your health insurance covers any of the machines and if it does, then it is better to opt for a machine that is covered under insurance.

Diabetes Blood Sugar Level Chart

It is important to understand the blood sugar level chart so that you can interpret the readings for yourself. All the glucometer comes with a blood sugar level chart so that you can understand if your sugar is well within range or if it is out of bound. It is best to refer to those charts, but in this section, we have listed the charts for your reference.

Below is a recommended chart for the blood glucose level for all different scenarios

Type of Patient On Waking Pre Meal (Fasting) Post Meal (90 Minutes)
Non-Diabetic NA 4.0 to 5.9 mmol/L Under 7.8 mmol/L
Children with Type 1 Diabetes 4.0 to 7.0 mmol/L 4.0 to 7.0 mmol/L 5.0 to 9.0 mmol/L
Type 1 Diabetes 5.0 to 7.0 mmol/L 4.0 to 7.0 mmol/L 5.0 to 9.0 mmol/L
Type 2 Diabetes NA 4.0 to 7.0 mmol/L Under 8.5 mmol/L

These were the normal sugar levels according to each class of the patient. However, there is also a criterion to diagnose diabetes. You can refer to the table below which will help you in understanding what are the criteria used by the doctor to diagnose the diabetes

Type of Plasma Glucose Test Prediabetes Normal Diabetes
Fasting 5.5 to 6.9 mmol/L


100 to 125 mg/dl

< 5.5 mmol/L


< 100 mg/dl

> 7.0 mmol/L


> 126 mg/dl

2 Hour after Meal 7.8 to 11.0 mmol/L


140 to 199 mg/dl

< 7.8 mmol/L


< 140  mg/dl

>11.1 mmol/L


> 200 mg/dl

Random NA < 11.1 mmol/L


< 200  mg/dl

>11.1 mmol/L


> 200 mg/dl

How to Use a Glucometer – Precautions and Tips

In this section, we are going to cover up to two parts. First is the usage of the glucometer and the second one is the precautions and tips associated with the use of a glucometer. Let us now have a look at these details.

It is very simple to use a glucometer. Simply load the lancing set with a new lancing needle. Load of the needle. Press it against the fingertip and press the button to release the needle. This will enable the lancing set to prick you and once the blood is dripping, put a drop on the test strip. Now insert the strip in the glucometer and wait 5 seconds for getting the reading. Once the reading is displayed, simply throw the strip along with the used needle.

Let us now look at some of the precautions and tips for using a glucometer:

=> Always use the branded glucometer and do not use the one which is locally assembled because they can be highly inaccurate.

=> Whenever you need to buy the strips, ensure that both are compatible. Remember that all the strips are not compatible with all the machines.

=> Check out the user guide before you plan to use the glucometer and see what are the things that need to be taken care of. This can vary from one machine to another.

=> Before inserting the strip in the glucometer, ensure that you have enough blood on the strip or else the machine might not be able to measure the blood glucose or you might not get the exact reading either.

=> Always wash and sanitize your hand before and after the test. Ensure that you do not leave the wound open as this can cause infection. Use a small band-aid to cover the wound.

=> It is always better to use the lancing needle at the side of the fingertip as this would hurt you less as compared to using the needle at the center of the fingertip.

=> Be consistent with your tests and ensure that you test the sugar levels at the same time every day. Variation in time can also alter the reading because of the metabolic process that goes into the body. Also, check your sugar levels on multiple occasions in a day.

=> It is also recommended to check the sugar levels before you drive on to indulge in any other physical activity.

Glucometer Vs. Lab Test: Which Is Better?

Lab tests and glucometer tests are the two most popular and widely used ways to measure the glucose level in the blood. Both of them have their importance and have their pros and cons. Here, in this section, we will be comparing these two ways of measuring the glucose level and will try to conclude which one of them you should choose for yourself.


The first thing that all users seek for while looking for the glucometer results is the accuracy. Although the Glucometer and Lab tests both provide nearly accurate results, if you were looking for the more accurate results that can be completely relied on, the proper lab results would be the better choice for you.

Ease of use

Another thing to consider is the ease of use. Although you won’t have to do anything in both the process, but the lab tests include different stages and is a lengthy process to determine almost similar results that you can get instantly by the Glucometers. So, the choice is yours, whether you choose the more reliable lab results or quicker glucometer results.

Time is taken to see the results

The next and probably the biggest difference between the results of Glucometer and lab tests is the time taken to get the results. The glucometers are meant for quicker results and have the sensors and advanced technology that measures the glucose level in the blood and shows the results almost in no time.

However, the lab tests take time and you may get the results in 2-3 days depending on the lab and clinic you have contacted for the test.


Another important thing about the lab test and Glucometer’s result is reliability. And although the results are accurate and reliable, if you are looking for the admission or want to move further with the tests, the Glucometer’s results aren’t considered as reliable.

There are some glucometers that have more passes and better algorithms to measure glucose levels, but in all, lab tests are considered as the best and the most reliable ones for checking glucose levels.

Better value

In all, if you look for better value, we will suggest you have a glucometer at home that can help you check the glucose level instantly and let you decide you about further actions. Also, if you need, you can then contact the clinic for more accurate results depending on which you can take the actions according to the doctor’s suggestions.

By having the Glucometers at home, you won’t have to rush to the clinic for the proper checkup and you can take the necessary actions according to the results. So, choose a reliable Glucometer and grab the best deal to keep an eye on glucose level in your blood.

In other words, if you are looking for a more reliable Glucose level check that can be taken for further process, we will suggest you go with the lab tests as most clinics do not take the Glucometer’s results as the reliable one for the further studies.


This was all the possible information about glucometer and we hope that the information helps you in managing your diabetes in a better way. You must refer to the user guide of the glucometer that you are purchasing and in addition to this, check out other details that may impact the result.

Take care of the precautions that you need to take while testing the sugar and never leave the wound open. Remember, a simple lifestyle change can save you from a lot of trouble.

Monitoring the blood sugar levels can be of great help and it can save you from several complications like kidney failure, eye damage, seizures and other such issues. Consult your doctor immediately if you notice high or low sugar levels.
