In Summary
A glucometer is a device that is used to monitor blood sugar levels. It tells you about your blood sugar levels in real-time and also keeps a record of it. This is useful for people with diabetes who must constantly monitor their blood sugar levels. This guide will help you understand how to use a glucometer and get the most accurate results.
It’s important to know how to use a glucometer at home since visiting a doctor’s office so frequently isn’t an option. Monitoring blood sugar levels at home is much easier than the traditional method of taking samples to the doctor for laboratory testing, and it does not take long for the results to reach the patient either. A glucometer is an electronic device that helps us with measuring blood glucose levels even from home. Glucometers are also known as blood sugar monitors. They are small, compact, and portable. You can even carry them in your handbag.
Who Needs to Use a Glucometer?
Even though we say that only diabetics need to use a glucometer, this is not entirely true. Doctors often recommend that people with prediabetes and gestational diabetes should also monitor their blood sugar levels. If you suffer from any of these diseases, you should get a glucometer and measure your blood glucose at home. If you are not sure if you need to use a glucometer, talk to your doctor. He or she will help you understand your risks and decide if monitoring your blood sugar levels is appropriate.
How Does a Glucometer Help You?
With a glucometer or blood glucose meter, you can check your blood sugar level at any time of the day. So you don’t have to wait for a lab appointment or fast before you can have your blood glucose checked. A glucometer is very useful for people with diabetes because it can help them:
Manage their blood sugar levels Avoid low blood sugar levels (hypoglycemia) Prevent high blood sugar levels (hyperglycemia) Detect early signs of diabetes Find out if their diabetes treatment is working
How Does A Glucometer Work?
A glucometer measures the amount of sugar (glucose) in a small drop of your blood. This is done by a process called electrochemical sensing. To get a reading, you need to prick your finger with a small needle (lancet). This will draw a small drop of blood. You then place this drop of blood on a test strip. The test strip is then inserted into the blood glucose meter. The glucometer will then give you a reading within seconds. It is important to know that the results of a blood glucose meter are not always 100% accurate. Therefore, you should have your blood glucose level checked by a doctor at least twice a year.
How to Check Blood Sugar at Home Using a Glucometer
Before we discuss how to use a glucometer at home, it is essential to understand the different parts of the device.
Parts of Glucometer:
Glucometer (Monitor) Test strip Lancing device Lancet Alcohol swabs Logbook
Let’s take a quick look at each one of these in turn:
Glucometer (Monitor): This is the primary device. It is used to measure the amount of sugar in your blood. Test Strip: The test strip is inserted into the glucometer. It is used to collect a small sample of your blood. Lancing Device: The lancing device is used to prick your finger and draw a small drop of blood. Lancet: The lancet is a tiny needle that is used with the lancing device. Alcohol Swabs: Alcohol swabs are used to clean your finger before you prick it. Logbook: A logbook is used to record your blood sugar readings.
Now that you know the different parts of a glucometer let’s look at how to use it.
Step-By-Step Guide to Using a Glucometer at Home
Step 1: Prepare the Lancing Device
To prepare the lancing device, proceed as follows:
Hold the lancing device with one hand and open its cap. Then insert a new sterile lancet into the lancet carrier. Then turn the protective cover of the sterile lancet and remove it. Finally, put the cap back on.
The lancet is now in the lancing device and ready for use.
Step 2: Prepare the Glucometer With Test Strip
Follow these steps to prepare the blood glucose meter with the test strip:
First, wash your hands with soap and water. Dry your hands thoroughly. Then take a test strip out of the container. Be sure to handle the test strip carefully so that you do not damage it. Then, insert the test strip into the glucometer. The glucometer should now be turned on. Match the code on the test strip container with the code on the blood sugar meter screen. Matching the code is important because it ensures that the test results are accurate.
Step 3: Perform the Finger Stick
Before you test your blood sugar levels, you need to select a finger and clean it thoroughly. The middle and ring fingers are most commonly used to test blood glucose levels. Follow these steps to clean the selected finger:
First, wash your hands with soap and water. Then dry your hands with a clean towel. Then use an alcohol swab to clean the selected finger.
Allow the selected finger to air dry before proceeding to the next step.
Step 4: Prick the Finger With the Lancing Device
After you have selected and cleaned a finger, you need to prick it with the lancing device. To do this, proceed as follows:
First, hold the lancing device in one hand. Then hold the selected finger with the other hand and stretch it out. Then place the lancing device on the side of the selected finger. Finally, press the trigger to release the lancet and prick the finger.
Step 5: Apply the Blood to the Test Strip
After pricking your finger, you need to apply the blood to the test strip. To do this, follow these steps:
First, hold the test strip in one hand. Then apply the blood to the end of the test strip with the other hand. Make sure that you apply enough blood to cover the entire test strip. Wait 5-7 seconds before proceeding to the next step.
Step 6: Read the Results
After applying the blood to the test strip, the glucometer will automatically start processing the results. Wait until the glucometer displays the results on the screen. Once the results are displayed, compare the results with the table provided. Now you can remove the test strip.
Step 7: Removing and Disposing of the Test Strip and Lancet
After you test your blood sugar level, you must remove and discard the test strip. To do this, follow these steps:
First, remove the test strip from the glucometer. Then dispose of the test strip safely (do not reuse the test strips).
Once you have removed and disposed of the test strip, you must remove and dispose of the lancet. To do this, follow these steps:
First, open the cap of the lancing device. Then remove the used lancet from the lancing device. Then dispose of the lancet safely (lancets must not be reused). Finally, put the cap back on the lancing device.
Some Important Precautions when Using Glucometer at Home
While testing your blood sugar levels, it is important to take some precautions.
Read the instructions that come with your blood glucose meter carefully. If you do not understand the instructions, ask your healthcare provider or pharmacist for help. Also, be sure to use only the lancets and test strips recommended for your glucometer. Do not reuse lancets and test strips. Clean the lancing device after each use. Store your glucometer and accessories in a cool, dry place. Look for the expiration date on the test strips and lancets before using them. Do not use expired test strips or lancets. If you have any questions about the proper use of your glucometer properly, contact your healthcare provider or pharmacist.
Continuous Glucose Monitor (CGM) - An abdomen-based system inserts a tiny sensor under the skin. Freestyle Libre - similar to a CGM but needs a scanner to get the values. Urine test - this can detect sugar but can’t provide the exact sugar levels.
