OneTouch Ultra 2 Glucometer

This glucometer is another high-quality one, very appreciated by lots of buyers. It is being dated, which means that it still uses coding and doesn’t have a high-contrast display. Coding means that the user must enter the code on the side of the test strip vial before he tests his blood. This process adds a few more seconds than most models available on the market today.

Even so, this product is still an excellent choice. The OneTouch Ultra 2 holds 500 readings in its memory function. The unit runs on one 3-volt coin-cell battery. Even if the unit offers software to track the glucose readings, you need to connect the meter to a computer. This connection must be made with a particular OneTouch USB data cable.

The glucometer offered by OneTouch is a fast and simple way to see the effect of food on your blood sugar results. The results will be shown in only 5 seconds. The device uses the latest technology to provide the user with the inside information he needs to manage his diabetes better.

Best Glucometers Guide

Those who have bought a glucometer before know exactly how to choose a high-quality model. People who are buying this type of item for the first time must be well-informed before making a decision. There are a few things you need to consider before choosing a glucometer. The product’s specifications are very important. Here is what must be taken into consideration.

Test time

Most people look for fast reading devices. They do not want to spend too much time checking their sugar level. It is understandable, which is why we recommend opting for a 5-second unit. You can even go for a 3-second glucometer, but keep in mind that a model like this is more expensive. Yet, we believe that 5 seconds is almost nothing, and everyone should be just fine with it.

Memory capacity

We are not sure if they still make glucometers without memory these days. However, it is being recommended to look at how many readings a device like this can remember. After all, it is essential to know the average to protect your health. It is true that you can write it down, but it is much easier with a unit that has a high memory capacity.

Blood volume

One of the best things about these units is that they don’t need too much blood to do their job. This is good news because people only need a small pinch. Note that some people are being scared of making this test, and they are very sensitive to blood. That’s why for them it is being recommended to go for a device that requires a small amount of blood.

Test strips

The best thing is to buy a glucometer that comes with test strips. One strip can be used only once, which means that you must have some extra strips. Lots of manufacturers produce and sell separate strips. This means that it won’t be a problem to buy them. You only need to make sure that the unit you buy has easy to find test strips. Note that incompatible strips can lead to inaccurate readings.

Diabetes is no joke, and those who have this disease must make sure they own a high-quality glucometer. There are many benefits of owning such a modern device. First of all, there is no need to go to the doctor regularly. Since you will have your personal glucometer, it will be much easier to check on the sugar level. Second of all, when eating new foods, it will be very simple to adequately track your diet.
