As a person with diabetes with a vested interest in technology, I know how cumbersome it can be to carry around multiple devices, including a mobile (cell) phone, a tablet, a laptop computer, and in the case of a person with diabetes, an insulin pump along with supplies, extra insulin, and the ubiquitous glucose meter with lancets, testing strips and extra batteries.
This can be a hassle and inconvenience, and for those fashion-conscious among us, a real drag. How would it be if you could reduce the bulky contents of your backpack, briefcase or coat pockets by combining some of them into one device?
Enter DARIO.
Dario is a small plastic device (104 x 211 x 11 mm (4.1 x 8.3 x. 4 in)) that weighs only 40 grams) and contains a lancing mechanism, storage for 25 testing strips, and a small piece the size of your thumbnail that, when connected to the headphone jack on your iPhone, iPod Touch, iPad or certain Android phones becomes your glucose meter. (Note that the list of supported phones and tablets is being updated on a regular basis, and can be found here.
Dario is like a Swiss Army knife, containing all components within “compartments”. When inserted in your phone’s 3.5mm headphone jack, the reader acts as your glucose meter that will read your strip (requiring an unusually small amount of blood and taking only six seconds to process), upload the result directly into the (free) Dario app, and store your data safely in the cloud, giving you access to your data from anywhere.
Currently approved for use in Israel, Australia, the United Kingdom, the Netherlands, New Zealand and the South Pacific, the list will be growing as other regulatory bodies approve the device and app. The cost of the device will vary by country, and you will be responsible for the cost of your lancets (while any lancets can be used, you can also purchase them from LabStyle (the parent company)), and a proprietary cartridge of 25 testing strips that fits snugly and easily into the Dario device. Certain countries with single-payer medical coverage (such as the UK and Canada) provide these supplies free-of-charge for Type 1 diabetics, however if you are a Type 2 diabetic and wanting to make use of this handy product, don’t let that stop you. The Dario device is free, and pricing for the supplies is similar to that of what you would pay for similar supplies for any other meter manufacturer. It is expected that the supplies will be available through your local pharmacy.
The first step to using Dario (after making sure you have the app installed on your phone or tablet) is to open the orange and white covers on either end of the device. On the white end, snap open the cartridge top and remove a testing strip, then press the strip cartridge cover closed and replace the white cap. Each cartridge contains 25 testing strips.
Open the orange cover, and with a lancet in hand, push it down into the lancing mechanism, carefully twist off the lancet cover and replace the cap.
The key to Dario is the strip reader that is concealed behind a black button on the side of the device. To access the reader, locate the orange button with a small arrow on it on the side of Dario and push it towards the white cap. The reader door pops open. Remove the reader and, with the Dario app open on your smartphone or tablet, insert the reader in the headphone (3.5mm) jack and insert the testing strip. The Dario app recognizes the insertion of the meter. The app now indicates that it’s waiting for you to do your blood test.
Pull down on the large black button (with down arrows on it) on the side of the lancing device to cock the lancet, then push down on the orange button just above to get a blood sample, put it up to the testing strip and wait six seconds for the results to appear. (Note: the lancing depth is adjustable, just as on any other lancing device.) Once the reading is displayed, you can enter (using on-screen ‘sliders’) details relating to that reading.
True, there are many smartphone apps for managing your diabetes. However, the Dario app, aside from having an exquisite interface, has unique features that make it stand out to merit your consideration. The Dario app gives you:
Don’t have your phone with you? No problem, you can manually enter all data manually directly into the app or on the web, and perform all other functions (emailing/printing reports, etc.)
A recent whitepaper on the accuracy of the Dario meter which is available on the company’s website, but in summary, “the Dario™ BGMS meets the acceptance criteria of ISO 15197:2013”. In addition, 2016 ISO 2013 will be mandatory for all glucose meters.
Dario already delivers the accuracy beyond the stringent error limits required by the ISO 2013. In my own testing, I found the results to be remarkably accurate in a side-by-side comparison with other meters.
To learn more, be sure to check out the brief but informative videos on the DarioHealth YouTube channel. Dario has an active online community on Facebook where users of the device and software share information and provide feedback directly to the company. Brenda Zeitlin, Marketing Director for Dario (an Israel-based company) said that much of what currently exists in the product comes from user feedback.
Dario is an innovative, useful device that I recommend without reservation. My hope for a new version might integrate the meter portion into the device itself, since I can see someone potentially losing that piece, making the device unusable. Your pocketbook, backpack and the environment will benefit as well.
