Question

What is it that doctors check during organ transplantation?

Answer 1

1: Blood group matching
Blood group matching: The donor and the recipient must have the same matching blood groups to prevent immune responses in the recipient that may lead to immunological reactions.

2: Tissue matching
Our bodies can differentiate between self and non-self tissues due to the presence of HLA (Human leukocyte antigens). These molecules are present on tissues and they need to match the donor to prevent graft rejection.
