Tissue Type Test: Why It Is Done
Content provided by Healthwise
Why It Is Done
A tissue type test is done to:
- See if the antigen pattern for donate 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 cannot 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.
- Find people who may have a high chance of certain autoimmune diseases.
