Blood plasma is the pale straw(yellow) coloured liquid component of blood that normally holds the blood cells in whole blood in suspension
Blood plasma compatibility is the inverse of red blood cell compatibility.
ANTIBODIES
Antibodies are important molecules our immune system makes to help protect ourselves against foreign things such as bacteria and viruses. Antibodies can also be formed in response to different blood groups.
PLASMA COMPATIBILITY TABLE
Table note: Assumes absence of strong atypical antibodies in donor plasma
Group O people have both Anti-A and Anti-B antibodies so group O plasma can ONLY be given to group O patients. If group O plasma were given to a group A patient, the Anti-A antibodies will attack the patient’s group A red cells.
Group A plasma contains anti-B antibodies. Group A plasma can only be given to patients who are group A or O i.e. only patients who do not have group B red cells.
Group B plasma contains anti-A antibodies. Group B plasma can only be given to patients who are group B or O.
Group AB plasma does not contain any Anti-A or Anti-B antibodies.
AB plasma can be given to patients who are group AB, A, B or O. Group AB donors are called “universal plasma donors” and their plasma can be safely given to any patient.
