Most women can donate umbilical cord blood. However, we must be certain that donated cord blood is safe for the recipient. Therefore, each donor of cord blood must fill in a health questionnaire asking about her health and the health of her family members, including questions about the pregnancy and any medication she might be taking. A part of the questions concerns the donor’s current and previous lifestyles and includes questions on sexual activity and drug abuse. Donors of cord blood must be legally of age (over 18).
