What three tests to doctors perform in order to determine if there is a potential organ match for a transplant?

Doctors typically perform blood type testing, human leukocyte antigen (HLA) typing, and crossmatching to determine potential organ matches for transplantation. Blood type testing ensures compatibility between the donor and recipient's ABO blood groups. HLA typing assesses the similarity of specific proteins on cell surfaces, which is crucial for minimizing rejection. Crossmatching involves mixing the recipient's serum with donor cells to check for any immune reaction, further confirming compatibility.
