The U.S. Food and Drug Administration (FDA), an ICCVAM member agency, is coordinating an upcoming public workshop at its White Oak campus in Silver Spring, Maryland. The goal of the workshop is to review test methods that are likely to predict clinical thrombogenic potential of blood-contacting medical devices. Information about the workshop will be provided at a later date. You are invited to participate in a pre-workshop assignment that will allow you to provide input on your current practices used for in vitro and in vivo thrombogenicity testing. Please complete the form "Pre-workshop assignment_distributed.pdf" using Adobe Acrobat or Adobe Reader by December 6th, 2013.

Click the button to download the form and open it using Acrobat Reader. The form should take approximately 30-60 minutes to complete. When you are finished, click "Submit" in the upper right-hand corner of the Acrobat Reader window to return your data. Your raw data responses will only be seen by FDA personnel, and the identity of all submitters will remain anonymous. The data will be aggregated and deidentified prior to use for developing panel sessions, and the compiled results will be presented to attendees of the upcoming workshop. Thank you for taking time out of your schedule to assist FDA. Your responses are extremely valuable, and may help to inform future guidance for regulatory submissions. If there are other contacts within your organization whom you feel would be appropriate recipients of this assignment, please feel free to forward this invitation to them.
