Question

— a type of blood test that measures the antigen compatibility of the organ being donated to that of the tissues of the recipient.


— medicine that makes the immune system less effective by disrupting the replication process of lymphocytes that produce antibodies.

Answer 1

1) Crossmatch (donor–recipient crossmatch; often done alongside HLA/tissue typing) — a blood test that assesses antigen compatibility and detects preformed anti‑donor antibodies.

2) Immunosuppressant (more specifically an antiproliferative/antimetabolite immunosuppressive drug, e.g., azathioprine or mycophenolate mofetil) — a medicine that reduces immune activity by disrupting lymphocyte replication and thereby lowering antibody production.
