Having a simple blood transfusion

On the day of your transfusion

You will usually be asked to come to the haematology day unit for your transfusion. Your appointment will be between 9am to 6pm. 

The time you stay in the day unit will depend on how many units you are having and the speed at which you can have your units. 

When you come to the unit for your transfusion, you should:

• bring your regular daytime medicine, including your painkillers, as we may not have them on the day unit.
• wear something comfortable

You might be in the unit all day, so you might want to bring something to eat (that does not need heating up). 

You might also want to bring something to keep you entertained, such as a book or laptop.

We might ask you to turn your mobile phone off during your transfusion.  

Do not bring children with you, as the day unit is an unsafe environment for children. We do not have any childcare facilities.

During your transfusion

During your transfusion, blood is given to you through a tube (drip), which is usually placed in a vein on your arm. This tube will be removed once the transfusion is complete. 

The number of units (bags) you are given depends on how much blood is needed to correct your haemoglobin level. You will usually be given 2 to 3 units of blood. Each unit will be given over 2 to 3 hours.

Leaving hospital

You can leave the hospital once the transfusion is finished. Sometimes, we might ask you to stay in overnight if it is very late.
