Hi all,

Maybe a year back I had put up a post on Non invasive glucometer of the future. It’s every patient’s dream to check his blood sugars without pain. We, doctors would always be happy to provide such a painless option to the patient. It would also help us in better treatment. There are so many companies trying different technologies for non invasive measurement of blood sugars. Finally I found one which sounds promising. I felt it’s worth a share with you people.

This particular glucometer is from a company called Grove instruments. The device uses near-infrared (NIR) spectroscopy to read the Blood Glucose Level. For the device to function properly and give accurate readings, the grey slot of the device must be placed over high blood flow area, such as the finger or the earlobe. It takes a real-time Blood glucose level from the blood using light.  The current international standard requires glucometer to differ from the blood standard by less than 20% before the instruments is released to the public for mass usage. The data from the clinical trials shows that Grove’s device has a mean average relative difference (MARD) of 8 to 12%.  Grove Instruments has maintained this MARD for the past two years.

Grove instruments claim that this is the first true non-invasive device that has a shot of making it to mass production for human usage. The other key aspect to this device is the time it takes to produce a result, 20 seconds or less. That is quicker than an individual can prick their finger and take a reading; making Grove’s device more time efficient, cleaner, and less painful than the current state of BGL testing. By having this device as a means of BGL testing, the average number of times a day an individual checks their BGL should move closer to the recommended four times a day. This technology has been patented. It is supposed to have cleared all safety standards and will be in mass production soon. I am trying to get it touch with the company to find out when this machine will be available in the market. Will update you people as soon as I get some good news
Till then..... Bye
Enjoy life!! 


  1. This is awesome........
    (but why two " is the" in para 2, line 1)

    1. dear Dr.Deepa.... thanks for your keen observation.. corrected!

    2. You really make it seem so easy with your presentation but I find this topic to be actually something which I think I would never understand. It seems too complex and very broad for me. I’m looking forward for your next post, I’ll try to get the hang of it.

    3. HI,
      initially everything looks complex... i will post the principle later on so it will be more easy...

  2. I have being researching about blood sugar conditions and treatment and reading your blog, I found your post very helpful.

    1. glad that my small bit of writing helped u in some way
