Grove Instruments Non-Invasive Glucose Monitor

If you haven’t heard of Grove Instruments, I recommend you check out their website and what they are doing. They claim to have developed a painfree/bloodfree way of testing your blood glucose level that leads the field in terms of accuracy, wiping traditional blood glucose meters out of the water. They state that:

Grove Glucose Monitor   The results of Grove’s clinical testing are unprecedented for a noninvasive device. The current international standard (ISO 15197) requires point of care glucose meters to vary from the blood standard by less than 20%. Grove’s MARD (mean average relative difference) has exceeded this standard (MARD 8-12%) for more than 2 years. The Company expects that soon a Grove device will be the world’s first-ever noninvasive glucometer to exceed all requirements of the ISO standard.

‘How does this cool device work?’ you might be asking. Good question. They say that:

Grove’s patented technology uses only very well perfused (high blood flow) sites – the fingertip or the earlobe. Grove’s technique also isolates the glucose signal to the blood compartment. Thus Grove’s glucometer uses neither an alternate site, nor an alternate fluid, rather, it gives a reading of real-time blood glucose, actionable for the management of diabetes. And it does it without pain, needles or a blood sample.

The test takes less than 20 seconds – considerably less than it takes to prepare the site, lance the skin, and process a blood sample as all currently available devices require. Real-time blood glucose in less than 20 seconds – obtained with a completely noninvasive (uses only light!) Grove Glucometer.

Reading further it seems all of the action comes from 3 laser diodes and an LED within the device. I’m really intrigued and can’t wait to see where this goes, and I know a lot of others in the DOC are also interested. Note that they are accepting applications of interest to participate in a clinical trial, which will be required before they can apply for FDA clearance.
