 Just like the donation of blood for transfusion, it is important that cord blood does not carry any infections that can be passed on. When volunteers donate blood to a blood bank, they are asked to fill out a confidential questionnaire about their risks for some infections like acquired immunodeficiency syndrome AIDS caused by the human immunodeficiency virus HIV, hepatitis, andor malaria. You will be asked questions like these in a questionnaire. You will also be asked some questions about your family medical history, to check for the chance of an inherited disease that could be passed on with the cord blood. This questionnaire will be completed within 48 hours of your baby being born, and will take about 15 minutes to complete. This questionnaire is used for screening purposes, and may result in your cord blood not being suitable for patient use, in which case the cord blood may be used for research purposes, for quality purposes to improve cord blood banking procedures, or discarded. Your medical chart, and that of your infant, will be reviewed to help determine whether you may have a disease which could be inherited and thus transmitted with the cord blood to a transplant patient who receives it. Additionally, you will be asked about your family ethnicracial background; this information is used to help match the cord blood to the patients.
