How to Use a Glucometer to monitor your Blood Sugar level?

Use a Glucometer

Monitoring the blood sugar level is an important part of diabetes management. This will help you to know what kind of activities or food is responsible for increasing your blood sugar level. It also helps you to control your diabetes from reaching the fatal limits. There are several ways to monitor your blood sugar but for most of the diabetes tests, you need to visit the laboratory. If you want to monitor your blood sugar at home then glucometers are the best.

What is Glucometer?


Glucometer has now become an integral part of the lives of diabetes patients. These are small sized portable device that requires a drop of blood to measure your blood sugar level in real time. Glucometer provides the readings by detecting the blood glucose content in your body with the help of glucometer strips. These strips contain some kind of chemicals which gives out the electric signals when blood comes in its contact. Therefore, you get the numerical results within few seconds.

Principles on which the glucometers work

The three most common and popular glucometer principle includes:

  • By glucose oxidase
  • By glucose dehydrogenase
  • By glucose dye oxidoreductase

Some meters and strips are coded. If you are using the glucose oxidase meter, it can interfere with your blood oxygen level and you will get the altered results. Similarly, glucose dehydrogenase can interfere with maltose and galactose contained in the solution for infusion. Therefore, the accuracy of the test result gets altered if you use the test strips of one glucometer on the other. This happens when the code on the test strips does not correspond to the code setting of your glucometer.

Simple steps to use the blood sugar test machine

steps to use the blood sugar test machine

With the help of portable and mobile based glucometer, it is possible to monitor your blood sugar level anywhere anytime. One has to follow the instructions mentioned in the user manual provided with the kit to use the glucometer effectively. All you need to be ready with glucometer, the test strip, lancing device, lancet, and alcohol pad to get started with blood test machine.

  1. The internal cap of the lancing device is twisted and removed so that the mounting part of the lancet insertion opens up
  2. You need to hold the lancet from its circular tip and then insert it into the mounting part of the device. The protective circular tip is then rotated to make it use.
  3. Internal cap is then re-attached to the mounting part of the device
  4. Select the depth of the blood sample between the range 1 and 5 where 5 means the deepest penetration
  5. Hold the lancing device and then pull on the sliding barrel. You should stop when you hear the click sound. It will release the button of the lancing device and make it ready for puncturing to get your blood sample.

Step 2: Cleaning hands and glucometer

Clean your hands and glucometer: You should clean your hands every time you use a sugar level test machine. Use a good handwash solution and gently rub your hands for atleast 20 seconds thoroughly. In case, you are outside and unable to wash your hands then you can use alcohol swab to clean your hands. Now completely dry your hands specially fingers by gently dabbing it on a towel. Now rub your palm softly so that the blood in your fingers gets warmed up.

Step 3: Preparation of glucometer and the strips

You should switch off the glucometer before inserting the blood sugar strips. Now you need to insert the glucose test strip in the glucometer’s test strip port ensuring that the contact bars face upwards. The glucometer will start automatically with a beep sound when the strip gets in its contact.

Step 4: Take the blood sample and monitor blood sugar level

When your device is ready for testing the blood sugar, you just need to get your blood sample and monitor your blood sugar. For this, you should follow the below mentioned steps or the instructions written on the test kit box:

Some devices use the hanging drop of blood while the others are one touch sugar test machine. A small drop of blood is used and drawn in with capillary action.
  3. A blood sample is hence applied on the narrow end of the already inserted sugar testing strip.
  4. Wait for around 5 seconds to get the most accurate results. You will get the results given in g/l, mg/dl, or mmol/l. You can get mislead if you do not pay attention to the unit of calculated reading.

Step 5: Dispose of the used lancet and test strips

You need to clear the blood from the fingertip after a sugar level check. Twist and remove the internal cap to open the mounting part of the lancet. The lancing device is cocked again after the round protective cover is removed and the lancet needle is inserted into it. Remove the lancet when the lancing device is locked. Now, you throw away the removed lancet and the sugar strips into the dustbin.

Technology enabled Glucometers

Glucometer manufacturing companies are now featuring technologies in the meters. They are currently using different measurement technologies to monitor your blood sugar level. You can sync latest and tech-friendly glucometers with an app, website or cloud. Some glucometers allow you to store your data on app or website synced with them while others will allow you to store readings in their own memory.

  • Glucometers with speaking mode: Such glucometers easy for those who have visual impairments. They simply vocalise the process to use diabetes test machine to complete the test without problem. User can hear the final reading of the test result as well.
  • Glucometers with multi-parameters: With the help of such type of glucometers, you can measure other parameters as well in addition to the blood sugar level check. Glucometers integrated with a thermometer, ketosis reader, cholesterol reader, lactometer, or more are also there.

Things to consider while buying a glucometer

There was a time when monitoring blood glucose levels were not so easy. People have to visit pathology and wait for their turn to give the blood sample for a glucose test.
