Laser Device Detects Blood Glucose Levels Without The Finger-prick

2 pictures Finger-prick tests to monitor blood glucose levels can be the bane of a diabetic's life. In a move that could put an end to such tests in the future, researchers at Princeton University have developed a non-invasive way to test blood glucose levels using a laser. Like a number of other blood glucose measuring research efforts we've seen in recent years, such as carbon nanotube "tattoos" and biochips that measure glucose in saliva, the Princeton team's method doesn't require direct analysis of a blood sample. Instead, the new approach detects the level of blood sugar by directing a specialized laser at a person's palm and measuring the amount of absorption by the sugar molecules in the person's body. Rather than the person's blood, the laser targets dermal interstitial fluid, which has a strong correlation with blood sugar. Instead of near-infrared light, which is used by many medical devices, the Princeton team's method uses mid-infrared light. This is because although near infrared light is not blocked by water, making it suitable for use in the human body, it interacts with a number of acids and chemicals in the skin, making it unsuitable for detecting blood sugar.

    I am not a pro in glucose meters. My experience is Johnson&Johnson OneTouch meters are more reliable, but the test strips are expensive - horribly expensive in some models. Accu-Chek on the other hand I’ve used briefly (model number - not sure) and found that reading varies from the standard. Still good. If you want accuracy, it should be OneTouch metres or recently launched Korean Glucometers - SD Codefree Plus Glucometer . The availability of test strips locally may be a problem with SD Codefree models. I am hoping we can get cheaper, non-invasive glucose monitoring system in India soon.

    Both gave good results ,only difference is of 5 to 7 unit + or _ unit than lab test but in emergency it is very useful
