Blood group compatibility
 |
| Red cell compatibility |
It is a general principle that blood components of identical ABO group and Rh(D) type as the recipient should be used for transfusion.
However, the requirements for particular components do vary especially in emergency situations or when stocks are limited.
Red cell, platelet and plasma components have specific compatibility requirements.
You should always refer to your local hospital policies and seek advice from a Consultant Haematologist or a Blood Service Transfusion Medicine Specialist if necessary.
