Lifescan blood glucose meter RRS feed

  • Question

  • We have tested Lifescan OneTouch Ultra2 glucose monitor to upload readings to healthvault. This monitor gives user an option to select meal context (Before meal/After Meal) and comments (choose from some preset values like after heavy exercise, not enough food, too much food etc) for each reading. When I uploaded the data from this monitor to healthvault using connection center, I got the glucose values and the meal context (measurement context), but not the comments that were selected for the readings. I was expecting the comments to go in CommonData.Notes field, but did not find so.

    I wanted to bring this to your notice because I have been told that Lifescan is going to release a new driver and is in a process to get the driver certified by Microsoft. It would be good to see this problem sorted out, or let me know if there is another way to get get the comments read from the meter into the healthvault.

    Also,please let me know if any other monitor is doing that already. We want to evaluate and select the right monitor for our study. Our criteria of selection is good insurance coverage for the device and the testing strips, ease of installation, ability to upload glucose values, meal context and comments.

    Thanks.

  • Thanks for posting the detailed query!  Here is what I found from the Ultra 2 device data upload to HealthVault.

    OneTouch Ultra2 device driver uploads and stores all the data (including comments) to HealthVault.  This "comments" and other data are specific to OneTouch devices and hence it is stored as custom data in data_other node.  data_other node is encoded and you need to decode it to read the device object property values.  If you're using latest HV SDK to read the values, it will encode it for you.  Down below is the full decoded XML for one of the reading from Ultra 2 device.  for "comments" property value, below is the GUID you should look for:

    <Property Key="{EFB03A56-6780-4176-8301-2BB71859521D}.1003">

        <Type>31</Type>

        <Value>Ex-3</Value>

    </Property>


    I'll check with LifeScan on this and see if they can display the coments in their web application OneTouch zoom.  Please feel free to post if you need any further information.
