How to use a Glucometer?

A Glucometer is the most important device in the possession of diabetic patients. It is a very easy-to-use device that is used to measure blood sugar levels. Whatever the type of diabetes, Glucometers are valuable devices that can keep you informed regarding low or high sugar levels in the blood. These devices are quintessential in managing diabetes and it is crucial for a diabetic to know how to use a Glucometer. 


What is a Glucometer?

A Glucometer, also known as a glucose meter, is a home blood glucose monitoring (HBGM) device. It is used to approximately determine the blood glucose level of a person. A lancet is used to prick the person’s finger for a small drop of blood, which is placed on a disposable test strip in which the meter reads and displays the blood glucose level.

A glucometer is easily available in the market at a very low cost. It can last from 2 to 5 years and only the test strips must be replenished regularly. Thus, it is a very feasible device to keep one’s sugar level in check.

How to use a Glucometer?

Glucometers are highly popular devices but very few people have the knowledge of how to use a Glucometer properly. Often, these devices come with user manuals and instructions, but it can be challenging for people who are not that practically astute. 

The following step-by-step instruction will help you become familiar with how to use a Glucometer.

1. The first step is to lay out all the necessary equipment required for testing. Those are a lancet, a new test strip, the Glucometer, and a dry swab of cotton.


2. Prepare the lancing device. This is used to pierce the skin to bring out a small drop of blood. The lancet has to be cleaned using alcohol or soap and water and mounted on a lancing device. The lancing device has a prime and releases action. The priming button has to be pulled back to load the lancet. The release button pushes the lancet forward and pierces the skin. The depth of penetration can also be set in a few lancing devices for varying skin thickness.

3. Place the test strip in the Glucometer in the given slot. Wait for the Glucometer’s intimation to put a small drop of blood on the free end of the test strip.

4. Use the lancet to pierce the fingertip on the side of the finger. Leave the first drop of blood and use the second drop of blood for testing. Place the second drop of blood on the test strip and wait for the Glucometer to display the results.

5. Use the dry cotton swab to apply pressure on the pierced skin to stop the bleeding.

6. Dispose of the lancet, the test strip and the used cotton swab safely.

7. Note down the results from the monitor of the glucometer. Keeping a record of your sugar levels can ease the management of diabetes.

The preprandial(before meals) blood glucose level must be between the range of 80mg/dL to 130mg/dL. The postprandial blood glucose level must be below 180mg/dL. Some Glucometers also show A1c levels and they should be below 7%.

When to use a Glucometer?

Doctors and experts in the field suggest checking for sugar levels before and after meals generally. But the frequency of glucometer tests can change based on the type of diabetes. 

Type 1 diabetes:

For this type of diabetes, the number of glucometer tests for sugar level ranges from 4 to 10 times per day. The usual testing times are before and after meals, before and after exercise and before bedtime. Since this type of diabetes causes irregular fluctuations in blood glucose, tests are highly frequent. Insulin treatment also plays a key role in the number of tests taken per day. 

Type 2 diabetes:

Type 2 diabetes requires less number of tests per day than Type 1 diabetes. Two to four tests are sufficient and once the typical patterns are understood, daily tests become redundant. The glucometer tests are taken before and after meals and before bedtime.

Benefits of using a Glucometer:

  1. Obtain information regarding your blood sugar levels, whether high or low.
  2. Understand how your body responds to your various activities like eating, exercising, etc.
  3. Recognize the effect of diabetes medication and insulin intake on your sugar levels.
  4. Follow the trend of your sugar levels in the long term and take necessary actions to normalize your blood sugar levels.
