Answered by GPT-5 mini AI
Antigens and antibodies.

Explanation: Transplant compatibility is determined by matching donor antigens (especially ABO blood group and HLA antigens) and checking the recipient for preformed antibodies against those donor antigens (crossmatch/PRA). Pathogens (and sometimes parasites) are screened for safety, but they aren’t compatibility tests.
