A brand of glucose meter that has all the key features and many more is the On Call® Glucose Monitoring System. The On Call brand of glucose meters’ are portable, easy to use and gives you an accurate result within few seconds. In this Review of On Call Glucose Meters, we will be comparing On Call Express vs. On Call Vivid vs. On Call Vivid Pal Glucose Monitors, to share with you our user experience on them.

Before jumping into the review, firstly let’s cover some background about diabetes and the importance of blood glucose monitoring.

What is Blood Glucose?

Glucose is a simple sugar derived from the carbohydrate, it supplies the body the energy it needs for physical and mental activities. It is the main sugar present in the blood and is known as ‘blood sugar’ or blood glucose.

Having enough energy from blood glucose is important. Still, one has to be careful and ensure that a healthy level of blood sugar is maintained to prevent an abnormally high level of blood sugar and ketones build up in the blood.

What is Blood Ketone?

Ketones are byproduct which results from the body using fat for energy instead of glucose, and this usually occurs when the body is low on glucose, or if you are diabetic and low on Insulin and your cells cannot absorb glucose. The abnormal or unhealthy blood sugar level is either a blood sugar level that is very high (hyperglycemia) or very low (hypoglycemia).

Importance of Keeping a Record of Blood Glucose and Ketone Levels for Diabetics

Unhealthy blood sugar level and high ketone-build up can result in serious health consequence. To prevent high or low blood sugar levels, and also a high level of ketones in the blood it is advisable to check your blood sugar level daily. Keeping an up to date record of blood glucose result will help you to observe the trend in your blood sugar level and how your daily activities and meal affect your sugar level.

Why You Need a Blood Glucose Meter?

To check the blood sugar level daily, one needs to have access to a blood glucose meter. For that, you need to have your own personal glucose meter, so you don’t have to share your lancing device and device with other people. This is to reduce the risks of spreading on contacting disease or illnesses such as HIV, hepatitis B and hepatitis C.

It is also important that the glucometer should be portable for easy carriage so that you can take it along when going out or traveling so that you can carry out the test whenever you want to.

Also, an ideal meter should be simple and easy to use and most importantly, it should give you an accurate result.

Tip: Remember, checking blood glucose and ketone level only wouldn’t suffice. You should check A1c Levels a few times a year too.

Why You May Need to Monitor Your Blood Glucose Daily?

It is very important to monitoring and keep track of your blood glucose because it helps you to understand how different foods, medications, and activities affect your blood sugar level. That is a major strategy of keeping your diabetes under control.

As noted, a household glucose meter, also known as a glucometer, is one of the key tools you can use to test in the comfort of your house and keep track of your blood glucose level.

If you are a diabetic patient on insulin, and if you have difficulty keeping your blood glucose level under control, if you are pregnant, if you have issues with ketone levels or if you have low blood glucose level, then you must monitor your blood glucose level a few times daily. This is to help you to manage unhealthy blood sugar levels (I.e. very high or very low blood sugar level) and high ketone build-up that can result in serious health consequence and medical emergencies.

High blood sugar level can result in long term complications like

Low blood sugar levels can also result in

The increase in the number of ketones in your blood can make your blood acidic and result in a condition known as diabetic ketoacidosis (DKA). The most serious effects of DKA include:

  • swelling in your brain
  • diabetic coma
  • a loss of consciousness, and
  • death

So, monitoring your blood sugar level will help you to know when to see your doctor for timely treatment and advice on the type of food, drugs, exercise and activities to avoid or partake in.

Now let’s look into On Call System for measuring your blood glucose levels for home use.
