Earlobe tests
Some monitors can check blood glucose levels through the ear lobes. However, according to 2019 researchTrusted Source, earlobe scanning is not as effective for people with type 1 diabetes, especially during periods of exercise or very low blood sugar.

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.
