Hello, _________

This is _______ calling from _________ Red Cross Blood Center. We want to invite you to take part in a research study about HIV infection in blood donors. This research is being done jointly by the ___________Red Cross Blood Center, Institute of Blood Transfusion of Chinese Academy of Medical Sciences, Johns Hopkins School of Medicine, United States National Institute of Health and local Center for Disease Control (CDC) Office.

You are being called because your blood sample is negative which means you are not infected with HIV that causes AIDS. The selection of healthy donors like you is done randomly using a computer program. You and other healthy donors will serve as the “Control Group” in this study. Participants in a control group are used as a standard for comparison.

Participation in this study is entirely voluntary. You may refuse to participate now or at any time during the process. We will ensure that all your personal information will be kept strictly confidential. You will be assigned a study number. Your answers will be identified by your study number, not by any of your personal information.

You will not be paid to take part in this study, but we will reimburse your transportation fees.

If you agree to join this study, you need to come to the center at a time that is convenient for you to answer a 20-minute questionnaire. A trained staff member from the local CDC (or the blood center) will ask you some questions about your health history and lifestyle.

This study protocol has been reviewed and approved by research ethic committees at Chinese Academy of Medical Science and Johns Hopkins School of Medicine, USA. If you have any question about the study, please call local blood center at _______________.

Do you have any questions about this study?

What is a good time for you to come to the center to complete the questionnaire?

Thank you for your time and help.
