A tissue type test is done to:
- See if the antigen pattern for donated tissue or
organs (including a blood platelet transfusion or bone marrow transplant) is a
match. The success of a transplant depends on how closely the antigen patterns
match. The antigen patterns are most likely to be similar when the donated
organ or tissue comes from a close relative of the person.
- See how
likely two people are related. If the antigen patterns are very similar, they
are likely to be related. But a tissue type can't prove definitively that two
people are related. A tissue type test may be done as part of a paternity test
to check to see if a man could be the father of a child.
