Testing Strategies
GlucoSync was tested using each of the four
supported meters. These meters, as well as the
blood glucose values stored in them were provided
by Dr. Kisor. Each meter contained 10 to 32
glucose values. A test server which mirrors the
live ecivon web server was setup to test upload
functionality. Upon completion of development,
the upload functionality was added to the live
ecivon server and tested. The completed
application was tested by the developers, Dr.
Kisor, and finally by a selected group of
Pharmacy students.
Dr. David Kisor of the Ohio Northern
University College of Pharmacy has supported the
development of www.ecivon.info, a website that
allows for information sharing between patients
and health care providers. People with
diabetes who currently use www.ecivon.info to
track their glucose levels do so by typing their
meter readings into forms manually, a process
that is both time consuming and prone to error.
Seeing the potential for improvement, Dr. Kisor
approached the College of Engineering with the
goal of enlisting computer science students to
automate this process.
Having been presented with this task, the
GlucoSync design team has formulated a software
solution that will upload readings from multiple
glucose meters to www.ecivon.info. Automating
the data entry process will serve as a timesaver
while eliminating the possibility of errors when
keying in data. An added expectation of the
GlucoSync team is the promotion of consistent
blood glucose level self-monitoring   

• GlucoSync met its functional requirements in all
  tests, including the following conditions
• A current ecivon user uploading a single value
  or multiple values at once to their account
• An unauthorized ecivon user attempting to
  upload glucose values
• An error occurs while submitting data via HTTP
  or inserting data into the ecivon database.
• A users ecivon password is changed but the
  GlucoSync password remains unchanged
• The tests were completed successfully on machines
  running Windows 98, 2000, and XP, using dial-up
  and broadband connections, with resolutions from
  800x600 and higher, and font sizes of 96 dpi and
  higher.

GlucoSync Development

• To insure compatibility with the existing
  ecivon infrastructure and optimize the
  convenience to the user and safety of the users
  data, GlucoSync was developed as a stand-alone
  application using Visual Studio .Net. The
  development relied on the following
• C for the main application code and user
  interface
• Visual Basic 6.0 for the serial communication
  and dial-up networking controls
• XML for glucose data storage and parsing
• Symmetric data encryption to preserve the
  privacy of the user
• A reusable abstract meter class for the quick
  addition of new meter functionality
• Embedded web browser for server communications
• JavaScript and PHP to upload readings to the
  ecivon database

The Application
Conclusion
GlucoSync is a ground-breaking software tool
providing diabetes patients with a simple and
powerful method of monitoring blood glucose
levels. In conjunction with www.ecivon.info,
glucose levels can be retrieved from a patients
meter and uploaded to the health education
website with a few clicks of the mouse. From
there, a patient's health care provider can
access and monitor these glucose levels as soon
as they become available on the website. The next
step in self-monitoring of diabetes, GlucoSync
provides many exciting features
Currently serving approximately 2,000 registered
users, with over 4,000 visitors per month, ecivon
will serve as the distribution point for
GlucoSync. All ecivon members will be able to
download GlucoSync from the ecivon website free
of charge. Already compatible with four of the
leading glucose meters on the market, GlucoSyncs
design makes adding more meters simple and
efficient and insures its relevance well into the
future. Ultimately, this application successfully
provides a safe and simple solution to the more
error-prone method of manual data entry to
ecivon. Furthermore, GlucoSync, in conjunction
with ecivon, helps to promote the self-monitoring
of diabetes and fulfill the primary goal of
ecivon, to make one experienced.

• Accurate and reliable data transfer,
  eliminating the mistakes of manual
  entry
• A fresh, user-friendly interface, allowing for
  the clear interpretation of readings
• The ability to retrieve and view readings at
  ones convenience, without a constant Internet
  connection
• Upload multiple readings at once to
  www.ecivon.info
• Support for the following leading glucose
  meters
• Ascensia DEX2 from Bayer
• Ascensia ELITE XL from Bayer
• OneTouch Ultra from LifeScan
• Freestyle from TheraSense
