Other thrombosis please call your local Donor Centre or 0800 GIVE BLOOD (0800 448 325) and ask to speak with a nurse.
The entire process of giving blood takes approximately 60 minutes. This includes filling in the Donor Health Questionnaire Form and the confidential interview with the nurse. The donation itself takes only 5-10 minutes, and finally 10-15 minutes to rest and have refreshment afterwards.
The rest period after each donation is an important part of the process. Your body is adjusting to a reduced blood volume and will be slowly moving fluid from your tissues back into your blood. Having a drink is also an important part of replacing the volume of blood you have donated.
For your safety it is strongly recommended that you rest for 10-15 minutes after the blood donation to minimise the risk of fainting.
A plasma donation takes longer than a whole blood donation - about 45 minutes for the collection period. The same comments apply as for whole blood donation.
