Question

Which of these are tested for compatibility before a transplant to ensure a high probability of success?
a. parasites
b. antigens
c. antibodies
d. pathogens

Answer 1

the answer is not parasites, or pathogens.  These are tested for before the donor and recipient are even matched

The antibody screen will test for antigens.  So I believe the answer is Antibodies.

Answer 2

Answer:

b. antigens

Explanation:

tissue typing is a type of blood test that measures the antigen compatibility of the organ being donated to that of the tissues of the recipient
