| Definitions | Delayed Faint: Is a faint that occurs after the donor has left the donation venue. |
| Obligatory | Must not donate if: a) History of an unexplained delayed faint. b) Two consecutive faints following donation. |
| Discretionary | If a donor with a history of fainting is accepted, careful observation is required. |
| Additional Information | An unexplained delayed faint occurs when there is no obvious reason for the faint, other than the history of donation. Events that might contribute to a delayed faint would be exertion, dehydration, exposure to an unpleasant situation, or standing for prolonged periods. A previous history of faints increases the likelihood of a severe adverse reaction to donation. |
