Donor History Questionnaire
The DHQ includes not only all of the questions that must be asked of U.S. blood donors, but also flowcharts outlining the steps to take depending on a donor’s answer to a question, educational materials for donors, and a list of medications that lead to donor deferral from donation. Blood centers may take only limited liberties with the DHQ. Centers can implement additional questions at the end of the questionnaire that lead to stricter standards for donors and likewise may opt for more restrictive interpretations of the answers to the questions in DHQ, but may not change the order of the questions or the content otherwise.
