Each year, we transfuse around 55,000 units of blood components, helping to save the lives of patients with serious injuries, those undergoing surgery, premature babies, and people receiving treatment for cancer and other conditions.
What are blood components and their functions?
Different components of blood are used to treat specific conditions. The most common types include:
- Red Cells – Carry oxygen around the body.
- Platelets – Help blood clot and stop bleeding.
- Fresh frozen plasma (FFP) – Contains clotting factors that help control bleeding.
- Cryoprecipitate – A rich source of specific clotting proteins used to treat certain bleeding disorders.
- Albumin – A protein used to expand blood volume, particularly in patients with liver disease.
- Prophylactic anti-D immunoglobulin – Given to RhD-negative pregnant women to prevent the development of antibodies that could affect future pregnancies.
Laboratory testing and matching
Our blood transfusion laboratories process approximately 65,000 blood samples annually for “group and screen” testing. These tests include:
- Determining blood type (ABO and RhD status)
- Screening for unexpected antibodies that may cause a reaction
- Ensuring compatible donor blood is safely matched for transfusion
- Kleihauer testing, which checks for fetal red blood cells in maternal blood
- Additional specialist tests as required
Patient blood management
We run a dedicated Pre-operative Anaemia Clinic for patients preparing for planned surgery. By assessing and improving blood levels—such as haemoglobin and iron status—before surgery, we help reduce the need for transfusion and improve recovery outcomes.
