There are various blood sugar monitors for people with diabetes. Some devices may require individuals to regularly prick their fingers, while others only require finger pricking for calibration purposes. They measure a person’s blood sugar levels and help doctors determine whether they need further treatment.
This article explores the different types of blood sugar monitors that do not require finger pricking and some products available for purchase. It also describes some factors that may help people choose the right device.
Some types of blood sugar monitors that do not involve finger prick collection for people with diabetes include the below.
Continuous glucose monitors
Continuous glucose monitors (CGMs) check blood sugar levels automatically at timed intervals. People do not need to prick a finger to test their blood sugar levels, but finger pricks may be useful to calibrate the device.
According to an
CGM devices can test glucose levels every 5 minutes. They come with a sensor, transmitters, and receivers or display units that provide regular reports, real-time data to an app or connected device, or a combination of both. Additionally, each separate part has its own price, and a person may need to replace sensors and transmitters regularly.
Some CGMs also require regular calibration using blood glucose meter (BGMs) readings, while others do not need frequent calibration. Individuals should follow the manufacturer’s instructions or seek help from a medical professional who can advise on using the device.
Advantages and disadvantages
CGMs offer various advantages and disadvantages.
Some advantages of these devices include the following:
- They can detect extreme fluctuations in blood sugar levels, according to a
- They can help people with type 1 or 2 diabetes improve their blood sugar levels, according to 2020 research.
- They reduce the need for finger pricks.
- They reduce the occurrence of experiencing low blood sugar levels.
However, some disadvantages include the below:
- Doctors may be unable to suggest a treatment plan using CGM data alone.
- A person may need a finger prick to calibrate the device.
- Several factors, such as user error, can reduce the effectiveness of the device, according to
- They typically
cost morethan BGMs.
Some monitors can check blood glucose levels through the ear lobes. However, according to
Integrity Applications, a company that focuses on needle-free blood glucose monitoring, manufactures GlucoTrack. This is a battery-operated noninvasive device that helps people with type 2 diabetes monitor their blood glucose levels through their ear lobes.
At the time of publication, these tests do not have approval from the Food and Drug Administration (FDA). However, Integrity Applications is planning to submit the device for trials to gain approved status.
However, individuals who have type 2 diabetes should speak with their doctor before using a blood sugar monitor, as they can determine whether they are safe and suitable for their condition.
Glucose breath tests may one day benefit people who have diabetes, and they are also available for purchase.
These devices do not directly measure blood glucose levels — they use glucose in a person’s exhaled breath to measure total blood glucose levels.
However, manufacturers often market breath monitors for people interested in keto diets and wishing to monitor their blood sugar levels.
A person should be cautious when shopping for a blood glucose monitor. A
Breath tests currently do not have approval for managing blood sugar levels. A person should speak with their doctor before purchasing a breath test, particularly if they are looking to monitor their levels closely.
CGMs can help people with diabetes monitor and maintain their blood glucose levels. While they do not involve finger pricking, they may be useful to calibrate the device.
Earlobe, breath, and other noninvasive devices may be beneficial for monitoring blood glucose levels, especially in children with the same condition and those who have cystic fibrosis. However, they are not FDA-approved, while some may need to undergo further testing to determine their safety and accuracy.
