Can blood glucose be measured without pricking the finger?

Blood glucose can now be measured without needles, thanks to the development of a new type of blood glucose monitoring device that uses non-invasive laser technology for glucose detection, eliminating the need for finger pricks. Details are as follows:

In recent years, a needle-free method for measuring blood glucose has been developed. This method utilizes laser technology to analyze the level of glucose in human blood. By employing non-invasive laser techniques, it enables blood glucose monitoring without collecting blood samples, avoiding unnecessary harm to the body, and achieving convenience, portability, and rapid testing. It represents a new approach to glucose monitoring and is an ideal solution for diabetic patients who require regular blood sugar checks and diabetes management. The needle-free measurement process consists of two main components: a laser source and a detector. The laser source emits light at a specific wavelength that passes through the skin and produces a certain reflectance. The detector captures this reflected light to determine blood glucose levels. This method is fast, safe, easy to operate, causes no discomfort to patients, and provides accurate results. Needle-free blood glucose monitoring offers many advantages. First, based on non-contact measurement principles, it eliminates the need for needles or lancets. Second, the use of laser technology significantly improves accuracy compared to traditional methods (such as finger-prick testing). Small-sized laser devices deliver reliable and precise readings while also reducing patients' fear of needle-based tests. Additionally, this needle-free method is highly portable and can be used at home or in the workplace, reducing the need for hospital visits and making glucose monitoring more flexible, quicker, and convenient—greatly benefiting patients.

In summary, blood glucose can be measured without needle pricks, although this method is generally more suitable for patients aged 18 and above. Note that if abnormal glucose readings are detected, it is essential to promptly visit a hospital for further evaluation. After identifying the cause, targeted treatment should be initiated.
