The University of Chicago Medical Center is offering free blood screenings for Celiac Disease on October 17, 2015. The test is offered for free, but registration is mandatory to qualify. Registration for the test opens on September 14th on the University of Chicago's Celiac Website.
If interested, I would recommend signing up as soon as possible once registration opens.
The University of Chicago also is offering Free Gluten Free Care Packages for people diagnosed with Celiac within the last 12 months. See this link for more information and to fill out a questionnaire in order to receive a care package.
