Best glucose meters 2021 – Buy best Glucometer

14 Min Read

The best glucose meters, also known as glucometers, are small handheld devices used for blood sugar testing. They are an important tool for managing diabetes. When paired with a testing strip, glucose monitors display your blood sugar level in that moment. In turn, that reading can help you make better decisions about medication (such as insulin), food and physical activity, and to figure out how each of those factors affect your blood glucose levels. Over time, a good glucometer can help you get an idea of what’s causing any blood sugar spikes or crashes.

Choosing from among the best glucose meters is largely your choice. But your doctor should have some general guidance for you (they will also advise how often to test your blood glucose levels). When it comes to cost, while the price of the actual glucometer is important. It’s actually the cost of testing strips that you need to watch out for. After all, at first the best glucometer for you might be the cheapest one you can find. But if the test strips are expensive, it’s going to be very costly in the long run. 

Let’s take a look now to see which the best one for you is.

5. Abbott FreeStyle Libre GlucometerBest glucose meter for fewer fingerprick tests

Abbott FreeStyle Libre Glucometer
Best glucose meters

One of the best glucose meters for freedom and comfort


Memory capacity: 90 days of typical use | Sensor: Water-resistant amperometric electrochemical (5mm H, 35mm D) | Warranty: One year

Reasons to Buy

  • Regular monitoring
  • Helps you spot patterns
  • Cuts down on fingerprick tests

Reasons to Avoid

  • No hypo alert

The Abbott FreeStyle Libre provides ‘flash glucose monitoring’ and reduces your need to take multiple fingerprick tests each day. Instead, this glucose meter works with a disposable 14-day sensor that’s applied to your upper arm, and a companion app (iOS, Android). As a system, the FreeStyle Libre tracks your glucose data for 90 days and provides instant readings whenever the sensor is scanned by the reader. The sensor’s blood glucose reading range is 40 to 500 mg/dL.

The Abbott FreeStyle Libre sensor measures the level of glucose in interstitial fluid, a method of measurement often used by continuous glucose monitors (CGMs). Still, experts recommend carrying out some standard blood glucose tests to ensure CGM-type devices are accurate. 

As such, the reader works with FreeStyle Optium blood glucose test strips (the test strip port sits at the bottom of the reader). The reader measures 95 x 60 x 16mm and weighs 65g, and has a battery life of seven days typical use. The microUSB data port (for downloading readings) doubles as a charging port.

The amperometric electrochemical sensor, meanwhile, has an eight-hour memory, with glucose readings stored every 15 minutes. The sensor has a small, flexible tip that is inserted just beneath the skin. The reader will store up to 90 days’ worth of blood glucose data captured by the sensor, and you can enter notes regarding physical activity, food and insulin to help you better understand how they affect your blood glucose. Reports are generated in the companion app and can be shared with your doctor as needed.
