Effective this past Monday I learned that Medtronic’s Carelink (Diabetes Management System) was going to be supported on a Mac operating system/Safari (browser). I haven’t uploaded my data in quite some time because of compatibility issues and getting a new iMac last fall. So hearing this news rekindled my drive for better reporting and being able to analyze my blood sugar numbers. The issue I have yet to see solved by them or any company to my knowledge is the issue of having multiple glucose meters. My mini doesn’t update my pump like my UltraLink does and therefore leaves out critical pieces of data. How nice would it be to have the ability to use SMS or Twitter to upload data to CareLink? So Carelink isn’t perfect, but I do like some of the reports you can generate and print quite easily.

The CareLink system is 100% web-based and you don’t have to download a thing outside of maybe having the latest version of Java or something.

Here is a screen shot of the log-in screen where it shows the last uploads and what device I used to load the data. Right now I use a CareLink’s wireless USB to get the data from my meter/pump to my computer without any wires. As you can see there are tabs across the top for: Home, Upload, Logging Data and Reports.


  • Below you will see the report options under the Report tab. The two that I’ve circled are the ones I use the most and have great information as long as there is a good amount of samples on your device to load. A small number of samples may lead you down the wrong path…
  • When you select the upload option, it will ask what device you want to upload from with the options being: Pump, CGM or Meter.
  • The Logbook option allows the user to load an entry manually such as carbs, exercise, A1c, etc. This is a nice area to keep track of past A1c results or to add in exercise to explain why there may have been a low.
  • The Summary report option can give a nice snapshot of readings by showing the average/high/low readings per day. The color coding represents what is in an acceptable range (green) and what is above or below. As you can see, I’ve got some work to do for improvement.
  • The distribution section below (Modal Day Hourly Report) shows a nice breakdown of what is in range (white), the numbers above (yellow), those below (orange) and the ones dangerously low (red). On the right side, the report shows the average, high, low and Std. Dev numbers for the time period selected. For those that may not know, St. Dev is a statistical term used to show variation from the average (mean). For the purposes of managing diabetes, you probably want the Std. Dev number to be low meaning there isn’t much scatter like you might see in my reports. An example of this would be a 200 and 20 that averages out to 110, but the variation from the 110 average is high. The Std Dev of these two numbers is 127. I would much prefer to have 120 and 100, that average out to 110 with a very low std. deviation. If you want to know more about this just drop me a message using the contact page.
  • This report below, Modal Day Periods is great because it segments out time periods throughout the day and provides the average, high, low and standard deviation for each segment. For example, you could have lunch set to any reading between 11AM and 1PM. The report will calculate the measures for any readings during that time. Really, it’s a nice way to see where problem areas may be and where you may want to focus. This is my favorite report and the one I use the most.
