blood transfusions

Post by Dragos_16 » Fri Jan 06, 2006 2:43 am

Hi , I appologize for my bad english . Can anyone help me with a little problem please? I don't understand why , in a blood transfusion , antibodies from the donor plasma do not react with antigens on the receiver red blood cells.
Thanks a lot.

what i know is that in blood transfusion not all of the components in the blood is transfered to the recipient. For example: only the RBC w/o the WBC.

Theorically: because the recepient's body has known the donor's blood as a part of it (self). So, no rejection happens..

Practically: in the hospitals, before transfussion is done, the donor's blood must be 'washed' to seperate those antibodies and to make sure that only RBC which enter the recepient's body..

O is the universal donor
AB is the universal acceptor
Blood can mixed together or clumping.

it's according to my old bio book....now, not again..each blood type can only be transfused to it's own type...because the ABO system is the only one type of blood classification from those other nineteen systems..
