DNA Paternity Testing (sometimes called parentage testing) uses DNA, the biological basis of inheritance, to prove or disprove the relationship between a child and an alleged father. It is based on the fact that we inherit half of our DNA from our fathers and half from our mothers.
HLA Typing/Matching. One of the tests you will have before you go on the waiting list is HLA typing, also called tissue typing. This test identifies certain proteins in your blood called antigens. Antigens are markers on the cells in your body, which help your body, tell the difference between self and non-self. This allows the body to protect itself by recognizing and attacking something that does not belong to it such as bacteria or viruses.
