The increased incidence of sedentary lifestyles have brought about a rise in the number of lifestyle diseases. The most common among them is Type 2 diabetes. One of the key factors in managing this disease is to keep a constant tab on one’s blood glucose levels. This involves monitoring of blood sugar levels several times a day and keeping a record of it.
Most devices used to measure blood sugar levels require numerous finger pricks in a day. This is either to obtain the blood sample or calibrate the device. Since most individuals are clueless about how to check diabetes without blood tests, this constant finger pricking turns out to be a discouraging factor. The pain associated with it acts like a deterrent in maintaining proper records of blood sugar levels. In such a scenario, the emergence of blood sugar testing systems, which do not require finger pricking, turns out to be a welcome alternative. Non-invasive methods of blood sugar testing makes managing diabetes a comparatively pain-free experience.

For the diagnosis of diabetes, a blood test may be mandatory. But once diagnosed, daily and frequent monitoring of blood glucose levels are required. In such instances, it is possible to check sugar levels in blood in a non-invasive manner. Know more about how to detect diabetes without blood tests, by understanding the way modern, non-invasive devices function.
These devices keep an automatic track of blood sugar levels throughout the day. They help in determining blood sugar trends and deciding the diet, medicines and exercises accordingly.
Continuous Glucose Monitors (CGMs) use tiny sensors to measure the amount of glucose in blood. The sensor is placed just under the skin, with the help of an adhesive tape. It reads the amount of blood glucose in the interstitial fluid (fluid under the skin) at frequent intervals. The data can be transferred to a smartphone or any other device, using a transmitter. The CGM data can then be downloaded easily. CGMs can also be programmed to sound alerts, in case of too high or too low blood sugar levels.
Fixing sensors to the earlobes is a novel, non-invasive technique of measuring blood glucose levels. The ear lobe is rich in capillaries, with a steady rate of blood flow. The absence of bones and negligible amounts of fats on the cartilaginous ear lobes are excellent factors to ensure an accurate reading.
The sensor is attached to the ear lobes. Combining ultrasound, electromagnetic and thermal technologies with physiological parameters, the blood sugar readings are transmitted to your smartphone through wireless networks.
These tests are among the modern, non-invasive methods utilising exhaled breath to assess blood glucose levels.
Breath tests make use of a similar technology like that of a breathalyser. Instead of alcohol, these test kits measure the amount of acetone in the exhaled breath. Acetones are volatile compounds that are proven biomarkers for diabetes. Their concentrations in the breath can be used to measure blood glucose volumes.
To make the transition from regular glucose meters to non-invasive glucose monitors, one must be thorough about their mechanisms. To know more about how to detect diabetes without blood tests, certain important factors must be considered while selecting the appropriate glucose monitor.
Companies around the world are investing a lot of their resources on researching non-invasive ways to track blood sugar. These methods aim at providing a painless and convenient experience to the users, especially the ones who need to frequently monitor blood sugar levels. Technologies like continuous glucose monitors, ear lobe tests and breath tests are excellent ways of frequently monitoring blood glucose levels, without finger-pricking. However, basic criteria like accuracy, reliability and ease must be considered while selecting the appropriate device.
When used correctly, these methods are mostly accurate. But, at times, the device sensors attached on the skin may be misplaced, resulting in faulty readings.
No, they are different. A glucose meter measures the blood glucose concentration at a particular time. A glucose monitor keeps a track of blood sugar levels for the entire day. Since it is a wearable device, it constantly monitors the glucose levels in the interstitial fluid.
