Blood sugar monitors are a blessing for diabetics. You can check your fluctuating glucose anytime from the comfort of your home. Luckily, you don’t necessarily need a super expensive blood glucose meter. There’s a whole variety of budget glucometers online offering excellent features at a minimal price. But at times, even the best, premium-quality glucometers can show you inaccurate results. You might dismiss it as a technical fault, but usually, it’s the little mistakes we make that lead to incorrect readings.


Let’s go through the common mistakes to avoid while using blood sugar monitors.

Can testing your sugar levels help control diabetes?

Yes, without a doubt! After a doctor performs a diabetes diagnosis test, they’ll advise you to regularly monitor your sugar levels. It’ll help you note whether the meds are working or not and get an idea about the foods that you need to avoid to reduce glucose levels naturally.

Taking daily glucose readings may also help you assess which physical activities are benefitting your diabetes.

How to test blood sugar at home?

Using blood sugar montiors at home is pretty simple. All glucometers contain a user manual that guides you on how to test your blood sugar properly. You will need to prick your finger, draw a drop of blood, and put it on a strip. It’s then inserted into the machine and within a few seconds, you’ll get a reading on a blood sugar monitor.


During this process, there’s a chance you might make a few errors that affect the final results. These are the 5 most common mistakes you should avoid while using blood sugar monitors.

1.  Improper pricking time

Blood sugar levels fluctuate throughout the day. So it’s important to take multiple readings daily. The best time to note your glucose levels is right before a meal, two hours after a meal, and before going to bed. These are the moments when the blood glucose levels are either too high or too low.


Your doctor can advise you on the best timings for using blood sugar monitors to check glucose. Since everyone has a different metabolism, you might be given a particular schedule that suits you. This is also why you should carry one of the best blood sugar monitors wherever you go. Several high-quality budget glucometers have built-in alarm clocks to set up daily reminders.


In short, being mindful of the timings of diabetic readings will save you from further complications.

2.  Testing the finger pads

Many people make the mistake of using blood sugar monitor lancet right on the fingertip. This region, also known as finger pads, has numerous nerve endings, making it one of the most sensitive parts.

Naturally, drawing blood from the middle of your finger pads will hurt a lot. Instead, prick the edges of your fingers. It’s not only easier but causes less pain than the tip. Also, the finger edges contain most of the blood supply.

Here’s another reason why pricking the fingertips is a bad idea. While doing daily chores, the finger pads are often in contact with stuff. This will increase healing time. However, the edges of your fingers rarely touch anything. Drawing blood from any other region other than fingers will give you incorrect results.


3.  Using old testing strips

Another rookie habit is using the same diabetes testing strips over and over again. This practice causes more harm than good. In fact, it’s one of the most dangerous mistakes you could make while using blood sugar monitors. Repeatedly using old strips makes you vulnerable to several infections.  Certain bacteria contaminate the blood-soaked strips and could lead to diseases.


So experts advise using a strip once only and discard it properly after checking blood sugar for the first time. Also, some quality monitors are designed to reject the old strips. This feature is really handy and prevents errors in readings.

4.  Exerting finger pressure

Sometimes, it’s difficult to draw blood for the sample because of poor blood flow to the fingers. So you might think of exerting pressure on fingertips to increase blood amount. But that’s another rookie mistake while using blood sugar monitors and can give you incorrect results.


This happens because the interstitial fluid, surrounding your body cells, comes out when you squeeze hard. Consequently, it might touch the strip and compromise the sample. The best solution is to avoid pricking at sites with low blood circulation and rather, get samples from a source with ample blood.

5.  Drawing insufficient blood

Another major mistake! Too little or too much blood on the strip could also give you false results. Experts agree that 0.5 ml of blood is enough for using blood sugar monitor strips. More or less than this will show improper readings.


Be mindful of the testing strips you choose. Find the best size for you that’s sufficient to get the correct amount for blood sugar monitoring. We hope this article gives you a clear idea of what rookie mistakes to avoid while using blood sugar monitors.

Invest in good quality diabetes testers, offering you a wide range of functions at a low price. You’ll find numerous budget blood glucometers online at an affordable rate. But no matter which glucose testing meter you choose, it’s important to take time to understand the process and follow the instructions correctly.
